Addiction treatment pioneered by WVU Rockefeller Neuroscience Institute featured on ’60 Minutes’ – West Virginia MetroNews

MORGANTOWN, W.Va. The work of the WVU Rockefeller Neuroscience Institute and Director Dr. Ali Rezai to help people suffering from Alzheimers disease and substance abuse disorder was the focus of the news magazine 60 Minutes on CBS Sunday evening.

Rezai, who was featured in two segments, said the addiction treatment uses a focused ultrasound on a specific area of the brain. He compared the effect of the ultrasound beam to rebooting the computer at home or work, or in this case, resetting the brain to remove cravings that allow the patient to focus on treatment and reduce detractors.

We are resetting the brain and allowing people more control, Rezai said during an appearance on MetroNews Talkline. Cutting the cravings and reducing them so people are not being driven by the next fix or the next drink because the cravings are down.

The process targets the area of the brain associated with addiction that malfunctions electronically and chemically, non-invasively. The procedure could become a groundbreaking treatment for many other disorders as well.

For addictions of all kindssubstances, alcohol, drugs, Rezai said. Its even for behavioral addictionseating disorders, gambling, or social media addiction.

Rezai said initial results suggest the treatments can give more control to the patient going through addiction treatment by reducing cravings. The patients are then more focused on the next aspect of recovery and growth.

The initial results are very encouraging in reducing cravings, drug intake, and even making people who have suffered for years and decades with addiction become abstinent, Rzai said.

The goal is to make this treatment available to more people, possibly in an out-patient setting. But, he described how the treatment is currently administered.

You come in, lay down in the MRI, a helmet goes on your head, and the ultrasound beam is delivered to the part of the brain involving addiction, then you get off the table and go home, Rezai said. Our goal is to work harder, do more research, and get more clinical trials.

For now, the treatment is reserved for those who have continued to suffer from addiction and have failed over a long period of time.

People who have tried in-patient treatment, residential treatment, and out-patient treatments and are taking medications and behavioral therapy are still failing, Rezai said. Even people who have overdosed or have had multiple overdoses, so its for people with severe addiction disorders.

Lust Over Love: The Psychology and Impact of Modern Music – Neuroscience News

Summary: Over 40 years, popular music lyrics have shifted from themes of love to lust, as revealed by a study of Billboards Top 40 songs from 1971 to 2011. This analysis indicates a decline in songs featuring love or a mix of love and lust, contrasting with a rise in songs focusing solely on lust, particularly in hip-hop/rap.

These trends reflect broader cultural changes towards accepting sexuality outside traditional romantic relationships. The study also considers the impact of these lyrical themes on young listeners attitudes and behaviors towards sexuality.

Key Facts:

Source: Neuroscience News

The lyrical landscape of popular music has undergone a significant transformation over the last four decades. A meticulous analysis of Billboards Top 40 songs from 1971 to 2011 reveals an intriguing shift: the prevalence of love themes has declined, while songs focusing on lust, especially without love, have surged, particularly in the hip-hop/rap genre.

This evolution in lyrical content not only mirrors but also potentially molds societal norms, especially regarding sexuality outside of love relationships.

This research offers a novel perspective on how sexual desire (lust) and romantic desire (love) are depicted in popular music, an influential medium in shaping public consciousness, particularly among adolescents and young adults.

The findings highlight a cultural shift towards greater acceptance of sexuality outside traditional romantic contexts. The analysis, encompassing 360 songs, sheds light on the interplay between lust and love themes in music lyrics and their evolution over time.

The decrease in songs with love themes and those combining lust and love, coupled with the increase in songs emphasizing lust in the absence of love, reflects changing societal attitudes.

These trends are particularly pronounced in hip-hop/rap music, though the change transcends genres. This shift may influence cultural norms and indicate a societal move towards embracing sexuality beyond the confines of love relationships.

Adolescents and young adults, who rank mass media as a crucial source of sexual information, are heavily exposed to these themes. This exposure shapes their sexual attitudes and scripts, potentially due to their limited personal experience.

Popular music, containing more sexual content than other media directed at young people, plays a significant role in this dynamic. The high consumption of music by 8- to 18-year-olds, averaging 16 hours a week, underscores its impact.

The study also explores the portrayal of gender roles in popular music. It documents a trend towards stereotypical gender roles, with women often depicted as sexual objects for male pleasure, particularly in music videos. This portrayal varies by genre, with hip-hop and rap displaying more explicit sexual content and objectification.

Notably, the study also situates these findings within the broader context of changes in popular music over time. Since the 1960s, popular music has evolved in terms of sound, content, and themes.

This includes not just the shift in sexual content but also changes in emotional tone (like sadder-sounding music), loudness, pitch variability, and references to antisocial behavior and substance use. These changes are reflective of broader social and cultural shifts.

The studys methodology, focusing on the themes of lust and love in lyrics, offers a unique lens to understand these trends. Unlike previous research that often focused on specific sexual acts or objectifying content, this study broadly categorizes themes into expressions of sexual desire (lust) and romantic love (love).

This approach provides a clearer picture of the evolving interplay between these two themes in popular music.

One key finding is that the increase in lust-focused themes is not simply an increase in sexual content overall. Instead, it represents a shift in how sexuality is framed moving away from romantic contexts towards a more casual or non-relational approach.

This shift, particularly marked from the early 2000s, suggests a cultural trend towards normalizing sexuality outside of traditional romantic relationships.

The study also investigates potential mediators of these trends, like the gender of the artist and the musical genre. Interestingly, the gender of the artist did not significantly influence the themes of lust and love in the songs.

However, the genre had a notable impact, with hip-hop/rap featuring more lust-focused themes and less love-oriented content compared to other genres. This genre-specific trend aligns with previous findings about the portrayal of sexuality in hip-hop/rap music.

Despite these insights, the study acknowledges limitations and calls for future research. It suggests that more detailed analyses, including annual assessments and broader genre sampling, could provide a more nuanced understanding of these lyrical trends.

Additionally, it recognizes the need to explore the impact of these themes on the listeners, especially adolescents and young adults, who are most exposed to and influenced by popular music.

In conclusion, the study offers a comprehensive view of how popular music lyrics have shifted over four decades, reflecting and potentially influencing societal attitudes towards love and lust. It underscores the power of music as a cultural barometer and a medium that both mirrors and shapes public consciousness, especially in the realm of human sexuality.

Abstract

Love lies: A content analysis of romantic attachment style in popular music

During adolescence, music consumption drastically increases and many adolescents become romantically involved. Popular songs often depict romance, and teens may incorporate tenets of these lyrics into their own romantic experiences.

Romantic attachment style is a primary indicator of relationship functioning, and individuals attachment style may shift according to romantic experiences they observe in media.

This study comprises a content analysis of the romantic attachment style portrayed in popular song lyrics. Findings revealed that more than 86% of songs illustrated an insecure attachment and various song/artist characteristics were associated with specific attachment styles.

We assert that parents, teens, and educators should be mindful of the lyrics adolescents listen to, working together to ensure adolescents navigate musics messages about romance in a positive way.

Autism and Beyond: Unveiling Overlapping Neurotypes – Neuroscience News

Summary: A study has uncovered significant overlaps in neurodivergent traits among children diagnosed with autism.

The research, which evaluated medical records of children referred for autism assessments, revealed that 76.2% of these children also exhibited traits associated with other neurotypes such as ADHD. Over half (55.6%) of the children assessed for autism potentially met the criteria for ADHD, indicating a high level of co-occurrence.

This study, a pioneering effort in Scotland, emphasizes the need for holistic assessments in child neurodevelopment, considering multiple neurotypes for accurate diagnosis and tailored support.

Key Facts:

Source: University of Glasgow

Three quarters of children (76.2%) who were diagnosed with autism also had traits of other neurodivergent neurotypesincluding traits associated with Attention Deficit Hyperactivity Disorder (ADHD), learning and motor differencesaccording to a new study.

The researchled by the University of Glasgow andpublished inPLOS Onefound that more than half (55.6%) of children referred for autism assessment may also meet the diagnostic threshold for ADHD, and certainly have at least some significant ADHD traits.

The study only looked at a small selection of possible neurotypes, suggesting the actual number of children with autism and other neurotypes may be higher.

This study is believed to be the first time the level of overlap of different neurodivergences in children has been studied in Scotland, where services aim to move away from single neurotype assessments to a more holistic assessment model, where all possible overlapping neurotypes are explored and identified.

The research showed there was apositive associationbetween the number of neurodivergence detected and an earlier age of referral and also suggested that neurodivergent females were less likely than males to be identified before the age of five. However, despite clinical overlap and co-occurrence of neurodivergence in children, just 26% of those in the study with other traits were investigated for an additional underlying diagnosis.

For the study, the researchers evaluated anonymized medical records of children aged between two and 17 years old who were referred for anautismassessment, using validated questionnaires to assess for neurodivergent traits.

The research suggests that validated questionnaires may help clinicians identify co-occurring neurodivergence at the firstassessment, allowing for earlier support and the development of whole-system insight into a childs neurotype.

Dr. Jason Lang, Clinical Senior Lecturer in Neurodevelopment and Honorary Consultant in Child and Adolescent Psychiatry, said, This study is extremely important, as it shows how vital it is to have aholistic approachto assessing children, to identify possible overlapping neurotypes properly. As well as a better understanding of the neurodivergent population as a whole, identifying a childs precise make and model will help provide better and more bespoke support for these children when needed.

However, it can be challenging for professionals to work across various neurotypes. As such, more work must be done to ensure services are truly holistic for overlapping traits to be properly identified. Our work suggests that one way to help is for services to use holistic questionnaires to gather this information.

And while this work is based inchildrens services, we would also recommend that similar studies be carried out in adult populations, where current approaches remain, to a large extent, siloed in approach.

Abstract

Towards system redesign: An exploratory analysis of neurodivergent traits in a childhood population referred for autism assessment

Childrens health services in many countries are moving from single condition diagnostic silo assessments to considering neurodevelopment in a more holistic sense. There has been increasing recognition of the importance of clinical overlap and co-occurrence of different neurotypes when assessing neurodivergent children. Using a cross-sectional service evaluation design, we investigated the overlap of neurodivergences in a cohort of children referred for autism assessment, focusing on motor, learning, and attention/activity level domains. We aimed to determine what proportion of children in a cohort referred for an autism assessment showed traits of additional neurodivergences, and what proportion were further investigated.

We evaluated anonymised medical records of children aged between two and 17 years referred for autism assessment. We used validated questionnaires to assess for neurodivergent traits. A weighted scoring system was developed to determine traits in each neurodevelopmental domain and a score above the median was considered to indicate a neurodivergent trait. Evidence of further investigations were recorded. We then examined the relationships between autism traits and traits of additional neurodivergence.

114 participants were included for evaluation. 62.3% (n = 71) had completed questionnaires for analysis. Of these, 71.8% (n = 51) scored greater than the median for at least one additional neurotype, indicating the presence of other neurodivergent traits, and 88.7% (n = 64) attracted a diagnosis of autism. Only 26.3% of children with evidence of additional neurotypes were further investigated beyond their autism assessment.

Our results demonstrate the extensive overlap between additional neurodivergent traits in a population of children referred with suspected autism and show that only a small proportion were further investigated. The use of standardised questionnaires to uncover additional neurodivergences may have utility in improving the holistic nature of neurodevelopmental assessments.

Emotional and Social Toll of Antidepressant Withdrawal – Neuroscience News

Summary: New research reveals that coming off antidepressants like Prozac can cause not only physical symptoms but also emotional, cognitive, and social difficulties.

The study involved in-depth interviews with 20 individuals who attempted to withdraw from SSRIs in the past year, highlighting the complex challenges they faced, including emotional overwhelm, reduced enjoyment in social situations, and a feeling of detachment.

Many participants managed their withdrawal with minimal medical support, emphasizing a need for more emotional support from GPs and flexible, patient-tailored tapering strategies.

While withdrawal often led to negative physical and social effects, some reported positive changes like a return to normal emotional states and improved physical health.

Key Facts:

Source: University of Bath

Coming off antidepressants is known to trigger physical symptoms, such as restlessness, fatigue and excessive sweating, but new research suggests people can also experience emotional and social difficulties, and changes in their thinking patterns when they stop taking antidepressants like Prozac.

This is especially true when people dont taper their medication but instead stop taking it suddenly, and when the process is not adequately supervised by a doctor.

Forthis study, researchers from the Universities of Bath and Bristol investigated the lived experiences of antidepressant withdrawal, and how it affects quality of life across multiple life domains.

They conducted in-depth interviews with 20 people who had attempted to withdraw from Selective Serotonin Reuptake Inhibitor (SSRI) antidepressants, such as Prozac, in the last year.

Raqeeb Mahmood, a PhD student in Psychology at the University of Bath and first author of the study, said: From these interviews, it became clear that the lived experience of withdrawal significantly impacts individuals wellbeing. The participants emphasised that withdrawal is not just about physical side effects, but it also affected their emotional, cognitive, and social functioning.

Challenges reported by study participants included feeling overwhelmed by their emotions, finding social situations less enjoyable, and feeling detached and less empathetic towards others.

Some symptoms were so severe, family and friends of the person coming off medication encouraged them to go back on it, said Mr Mahmood.

Some patients found the early stages of withdrawal the first few days or weeks most challenging, while others struggled more in the later stages, which might come several months after they started trying to come off their medication.

The study, which has been published in the journalHealth Expectations, suggests patients often manage their withdrawal alone, due to limited GP involvement and a lack of NHS online resources or evidence-based guidance.

Mr Mahmood said: The study participants expressed a desire for more emotional support from their GPs and emphasised the importance of flexible tapering, where the process of coming off medication happens at a pace tailored to them.

They also mentioned the importance of people timing their withdrawal attempts for less stressful or busy periods in their lives, to give them a better chance of coming off them without experiencing significant difficulties.

Dr Graeme Fairchild, Reader in Psychology at Bath, senior author on the study and project co-supervisor, said: Some of the people described social situations as feeling like a chore they felt as if they were just going through the motions of regular life. They also talked about being more difficult to live with or felt that their partners or family members wanted them to go back on their medication.

These impacts of antidepressant withdrawal on peoples social relationships are less widely known but need to be communicated to patients considering coming off their antidepressants.

Dr Katherine Button, Senior Lecturer at Bath, study co-author and project co-supervisor, added: Over half of the participants described withdrawal negatively affecting their relationships with others, with family members getting the brunt of their increased snappiness, for example.

This is an important finding as family members are often a key source of social support so being prepared for these potential changes may help both the patient and their family navigate the withdrawal process.

All of the participants encountered negative physical withdrawal symptoms which were short-lived for some, but continued for several weeks or even months for others. However, some positive effects of withdrawal were also reported, such as people feeling like their emotions were returning to normal (rather than being blunted by their medication).

Some participants reported positive changes in their thinking patterns and found it easier to recall positive memories. Some also experienced positive physical health effects, including weight loss, and identified exercise as a crucial protective factor and coping mechanism.

Abstract

The lived experience of withdrawal from Selective Serotonin Reuptake Inhibitor (SSRI) antidepressants: A qualitative interview study

Our knowledge of the broader impacts of antidepressant withdrawal, beyond physical side effects, is limited. Further research is needed to investigate the lived experiences of withdrawal, to aid clinicians on how to guide patients through the process.

To explore antidepressant users experiences and views on the withdrawal process and how it affected their quality of life across multiple life domains.

We conducted in-depth qualitative interviews with 20 individuals from the community who had attempted to withdraw from Serotonin Reuptake Inhibitor antidepressants in the past year.

Semi-structured interviews were conducted online. A topic guide was used to ensure consistency across interviews. The interviews were audio-recorded and transcribed verbatim and analysed using inductive reflexive thematic analysis.

Five themes were generated. The first highlighted the challenges of managing the release from emotional blunting and cognitive suppression following antidepressant discontinuation. The second related to the negative impact of withdrawal on close relationships and social interactions. The third showed that concurrent with negative physical symptoms, there was a positive impact on health (exercise was reported by some as a coping mechanism). The fourth theme focused on support from GPs and families, emphasising the importance of mental health literacy in others. The final theme underscored the importance of gradual and flexible tapering in enabling a manageable withdrawal experience,and the consideration of timing.

The lived experience of withdrawal significantly impacts individuals well-being. Participants emphasised that withdrawal is not just about physical side effects but also affects their emotional, cognitive, and social functioning.

Eight people attended individual online meetings to share their experiences of antidepressant withdrawal to help inform the study design and recruitment strategy. Insights from these meetings informed the development of the topic guide. Questions about GP involvement, family relationships, and mood and thinking changes were included based on this PPI work. This ensured the inclusion of topics important to antidepressant users and facilitated the researchers questioning during the interviews.

From baseball to neuroscience to the Big 12, Pat Suemnick is hitting his stride with West Virginia – Blue Gold Sports

Pat Suemnick has scored a career high in points in three of his last four games. However, if you ask Suemnick, basketball is the last sport he thought hed end up playing and his focus is on things that take place off the hardwood.

Growing up in Wisconsin, Pat Suemnick always excelled at basketball. But baseball was more of his sport early on in high school.

I thought I was going to be a baseball or football player and then I just kept growing, Suemnick said.

Suemnick went to Denmark High School, where he played football, baseball, and basketball. Suemnick said he was throwing at least 90 miles per hour in high school, but as he got taller, basketball seemed more realistic.

My dad is 6-foot, my mom is 5-foot-7. I didnt expect to be 6-foot-8. I kind of just played everything, Suemnick said. I never really pictured playing in the Big 12 as a kid. As I kept growing, got to be like a 6-foot-4 freshman in high school, I was like, man, I should probably start playing some basketball, maybe I can get my school paid for.

Suemnick would end his senior year in high school averaging 19.1 points and 10.2 rebounds per game in his final season. That year, Suemnicks squad went to the state championship game, ultimately falling short. For him though, making that game helped him get noticed by several schools.

I didnt have a single offer in high school until we made it to state. No ones watching us. Unless youre successful, unless youre making it. I was a 6-foot-8 kid, averaging three dunks a game. I had a game with 20 rebounds but no ones recruiting me, just because the area were in, Suemnick said.

From there, Suemnick attended prep school, going to the Bosco Institute in Crown Point, Indiana. In one season there he averaged 14.7 points and 7.3 rebounds, getting him looks by many high major Division I programs. Then came the COVID-19 pandemic, and the offers and contacts went away with it.

I was having a whole bunch of schools interested, Suemnick said. COVID hit, we never got to finish our season, and the schools were like, COVID is going to be gone in a month, youll just take the visit after. Obviously that didnt happen. Ended up losing all the big schools I thought I was going to end up going to.

With that, Robert Morris continued to contact Suemnick. He never stepped foot on their campus and didnt take a visit before committing.

Suemnick played in 16 games in his one season at Robert Morris but didnt see the floor much during his time there. He decided to leave RMU, and received heavy amounts of interest once again. This time for Suemnick, he went back to junior college, before coming to the type of place he thought he would have ended up all along.

Now in his second year with WVU, Suemnick has started to see his role expand. Some of it was not supposed to happen as Jesse Edwards went down with an injury. Suemnick got his first start on Dec. 30 against Ohio State.

He scored two late buckets to help send that game to overtime and has been playing with a increased amounts of confidence ever since then.

When they are playing better you can tell. You can tell that theyre carrying themselves differently, theyre carrying themselves with a lot more moxie and confidence, West Virginia interim head coach Josh Eilert said. Thats starting to help his mentality each and every day in practice and hopefully it continues to snowball in that direction.

Suemnick was a big reason why West Virginia beat No. 25 Texas this past Saturday, and if the Mountaineers are going to have success the rest of this season, he will have to continue to be a difference maker.

For Suemnick though, he recognizes life is more important than basketball. Suemnick has loftier goals off the court. Suemnick knows many recognize him as No. 24 Pat Suemnick on Mountaineer Basketball, but he says he knows there are things bigger than sports.

Theres a lot more behind the scenes. Im big into neuroscience and listening to ted talks and planning things that are a little bit bigger than sports for my life. Im always trying to promote being more than just an athlete, Suemnick said.

Suemnick said he doesnt have a set career path. He had to recently change his major to fit the basketball portion of being a student-athlete.

Its not really set up for you to be a neuroscience major and a basketball player, Suemnick said. Ive just been trying to take as much classes as I can that Im interested in but keep basketball as the main thing.

Suemnick hitting his stride on the court is no accident. He has somewhat waited his turn behind multiple big men over the last few seasons. He was thrust into a role that took him time to settle into. For him though, it goes deeper than basketball. While he may be slamming home dunks against the Longhorns, he still finds joy playing in softball leagues, or learning about the human body.

I guess every game you go out there just trying to do what you can, make the most of your opportunities, Suemnick said. Ive really just been capitalizing on the opportunities Ive been given.

Unveiling the Secrets of the Brain Cortex: New Discoveries in Neuroscience – Medriva

Unveiling the Secrets of the Brain Cortex

In a breakthrough study, a team of neuroscientists from the Massachusetts Institute of Technology (MIT) has discovered distinct patterns of electrical activity in the brains cortex. This discovery uncovers the complex mechanisms of the brain and reveals new understandings of how our brain processes information and what could be going wrong when disorders occur. The research findings are consistent across many brain regions and animal species, including humans, suggesting a fundamental principle of brain organization.

The brains cortex, the outermost layer responsible for our complex thinking abilities, is divided into six layers. Each layer has its unique role and function. The MIT team found that these layers exhibit different patterns of electrical activity when the brain is in various states, such as awake, asleep, or anesthetized. The topmost layers show rapid gamma wave activity, while the deeper layers display slower alpha and beta wave activity. This discovery provides valuable insights into how the brain separates external sensory information from internal cognitive states.

The findings from this research also shed light on neuropsychiatric disorders such as attention deficit hyperactivity disorder (ADHD) and epilepsy. Imbalances in these oscillations the gamma, alpha, and beta waves could be implicated in these disorders. The researchers are exploring the potential of measuring and rebalancing these oscillations for diagnosing and treating neurological disorders. This discovery could eventually lead to the development of new treatments that target the specific electrical patterns associated with different disorders.

Further reinforcing the complexity of the brain cortex, the research also shows that different types of neurons in the cortex exhibit unique patterns of electrical activity. These unique patterns could be key to understanding the different cognitive functions associated with each neuron type. From sensory processing to decision-making, these patterns could underpin our most complex cognitive abilities.

While this discovery is a significant step forward, there is still much to learn about the brain and its complex mechanisms. The MIT teams findings are a promising start to a new era of neuroscience, one that leverages a deeper understanding of the brains electrical activity to improve diagnoses and treatments for neurological disorders. As we continue to unravel the mysteries of the brain, we move closer to more effective and targeted interventions for a range of debilitating neurological conditions.

Love’s Chemistry: How Dopamine Shapes Bonds and Breakups – Neuroscience News

Summary: Researchers uncover how dopamine, a key neurotransmitter, varies in response to social interactions, distinguishing between intimate and casual relationships. Their research, conducted on prairie voles, sheds light on the neurochemical dynamics of pair bonding and grief.

The study demonstrates that dopamine surges in the presence of a life partner, fueling the desire to maintain the bond. Interestingly, this surge diminishes after prolonged separation, suggesting a neurological reset that might aid in overcoming heartbreak.

Key Facts

Source: University of Colorado

Hop in the car to meet your lover for dinner and a flood of dopamine the same hormone underlying cravings for sugar, nicotine and cocaine likely infuses your brains reward center, motivating you to brave the traffic to keep that unique bond alive. But if that dinner is with a mere work acquaintance, that flood might look more like a trickle, suggests new research by University of Colorado Boulder neuroscientists.

What we have found, essentially, is a biological signature of desire that helps us explain why we want to be with some people more than other people, said senior author Zoe Donaldson, associate professor of behavioral neuroscience at CU Boulder.

The study, published Jan. 12 in the journalCurrent Biology, centers around prairie voles, which have the distinction of being among the 3% to 5% of mammals that form monogamous pair bonds.

Like humans, these fuzzy, wide-eyed rodents tend to couple up long-term, share a home, raise offspring together, and experience something akin to grief when they lose their partner.

By studying them, Donaldson seeks to gain new insight into what goes on inside the human brain to make intimate relationships possible and how we get over it, neurochemically speaking,when those bonds are severed.

The new study gets at both questions, showing for the first time that the neurotransmitter dopamine plays a critical role in keeping love alive.

As humans, our entire social world is basically defined by different degrees of selective desire to interact with different people, whether its your romantic partner or your close friends, said Donaldson. This research suggests that certain people leave a unique chemical imprint on our brain that drives us to maintain these bonds over time.

For the study, Donaldson and her colleagues used state-of-the art neuroimaging technology to measure, in real time, what happens in the brain as a vole tries to get to its partner. In one scenario, the vole had to press a lever to open a door to the room where her partner was. In another, she had to climb over a fence for that reunion.

Meanwhile a tiny fiber-optic sensor tracked activity, millisecond by millisecond, in the animals nucleus accumbens, a brain region responsible for motivating humans to seek rewarding things, from water and food to drugs of abuse. (Human neuroimaging studies have shown it is the nucleus accumbens that lights up when we hold our partners hand).

Each time the sensor detects a spurt of dopamine, it lights up like a glow stick, explained first-author Anne Pierce, who worked on the study as a graduate student in Donaldsons lab. When the voles pushed the lever or climbed over the wall to see their life partner, the fiber lit up like a rave, she said. And the party continued as they snuggled and sniffed one another.

In contrast, when a random vole is on the other side of that door or wall, the glow stick dims.

This suggests that not only is dopamine really important for motivating us to seek out our partner, but theres actually more dopamine coursing through our reward center when we are with our partner than when we are with a stranger, said Pierce.

In another experiment, the vole couple was kept apart for four weeksan eternity in the life of a rodent and long enough for voles in the wild to find another partner.

When reunited, they remembered one another, but their signature dopamine surge had almost vanished. In essence, that fingerprint of desire was gone. As far as their brains were concerned, their former partner was indistinguishable from any other vole.

We think of this as sort of a reset within the brain that allows the animal to now go on and potentially form a new bond, Donaldson said.

This could be good news for humans who have undergone a painful break-up, or even lost a spouse, suggesting that the brain has an inherent mechanism to protect us from endless unrequited love.

The authors stress that more research is necessary to determine how well results in voles translate to their bigger-brained, two-legged counterparts. But they believe their work could ultimately have important implications for people who either have trouble forming close relationships or those who struggle to get over loss a condition known as Prolonged Grief Disorder.

The hope is that by understanding what healthy bonds look like within the brain, we can begin to identify new therapies to help the many people with mental illnesses that affect their social world, said Donaldson.

Fly brain, mouse brain, worm brain: They all network the same – EurekAlert

New York, January 17, 2024 In all species, brain function relies on an intricate network of connections that allows neurons to send information back and forth between one another, commanding thought and physical activity. But within those networks a small number of neurons share much stronger connections to one another than all the others. These abnormally strong connectionsknown as heavy tailed based on the shape of their distributionare thought to play an outsized role in brain function.

Researchers have long wondered how neural networks are able to rearrange to form these rare connections and whether the formation process is species specific or governed by a deeper shared principle. With the publication of a new paper in the journal Nature Physics, scientists at the CUNY Graduate Center Initiative for the Theoretical Sciences (ITS), Yale, University of Chicago, and Harvard are getting closer to answering these questions.

To understand these very strong connections between neurons, you can think of a social network: Some connections, like those with your best friends and family, are much stronger than most, and these are very important in the network, explains Christopher Lynn, the papers first author, previously a postdoctoral fellow with the ITS program and now an Assistant Professor of Physics at Yale. Until recently, we didnt have a way of teasing out the mechanism by which these rare connections come together, but advances in particular forms of microscopy and imaging now allow us to take a peek into how it happens.

The researchers analyzed large, openly available datasets of the wiring between neurons in fruit flies, mice and two worm species (C. elegans and Platynereis). The catalogued data, which was collected using volume electron microscopy and high-throughput image processing, allowed them to compare networks across multiple species, looking for similarities and differences in the way heavy tailed connections form.

The scientists created a mathematical model to describe how they believed wiring between neurons can rearrange to develop these strong connections. This model was based on a decades-old mechanism from neuroscience known as Hebbian plasticity, which says when neurons fire together, they wire together. The researchers showed that this Hebbian plasticity leads neurons to form the types of heavy tailed connections they observed in the data. Whats more, when they included neural activity in the model, a second key feature of neural network structure emerged: clustering, or the tendency for neurons to form tightly knit groups.

Our model was based on the assumption that neurons rearrange and connect under a mixture of Hebbian and random dynamics, said Lynn, noting that neurons sometimes connect for specific reasons, but other times randomly. The research teams model proved applicable across species, showing how simple and general principles of cellular self-organization can lead to the very strong connections and tightly connected networks that exist in the brain. The findings suggest that neuronal network formation isnt dependent on species-specific mechanisms, but instead might be governed by a simple principle of self-organization. This new knowledge could provide an important foundation for investigating brain structure in other animals and may even help to better understand human brain function.
