Your child’s overreactivity to touch might actually start in the skin’s nerves rather than the brain’s processing center.

Learn how a simple shift from boss to coach can break the cycle of stress and physical pain for neurodivergent teens.

Today’s updates explore the biological foundations of sensory processing and social behavior, the formation of a new science-led autism advocacy group, and practical strategies for managing chronic pain and daily organization in neurodivergent families. (Blog Name: Living on the Spectrum)

Patrik Ernfors and David Ginty received the 2026 Brain Prize for identifying how the somatosensory system detects touch and pain. Ernfors classified sensory neurons through gene expression patterns, while Ginty detailed how these neurons differentiate between various touch types to transmit signals to the brain.

Ginty’s research indicates that touch overreactivity, frequently observed in autistic individuals, may originate in the peripheral nervous system rather than the brain. This finding shifts the focus of potential treatments to the network of nerves outside the brain and spinal cord.

Researchers are currently applying these insights to develop and test new interventions. These approaches aim to address sensory processing differences by targeting the specific neural pathways identified in the award-winning studies.

Studies using mouse models show that astrocytes, star-shaped glial cells, actively regulate oxytocin to drive social behaviors. This research suggests that social challenges in autism may involve these non-neuronal cells modulating emotional states.

In the lateral septum, male mice possess fewer astrocytes and receptors than females. Suppressing these cells in males specifically hindered their ability to recover from social fear, suggesting a biological basis for sex-based differences in social anxiety.

A positive feedback loop in the hypothalamus allows astrocytes to sense oxytocin and use retinoic acid to prompt neurons to produce more. This mechanism prevents the rapid degradation of the neuropeptide, maintaining the levels necessary for sustained social interaction.

The Autism Science Foundation and the Coalition of Autism Scientists established the Independent Autism Coordinating Committee (I-ACC). This group of 12 scientists and advocates provides a research-focused alternative to the federal government's Interagency Autism Coordinating Committee (IACC).

The I-ACC formed in response to concerns that the federal committee lacks sufficient research expertise and may allow the promotion of unproven theories. The new group aims to focus exclusively on evidence-based causes and treatments while serving as a credible resource for the media.

Committee member David Mandell states the group will offer high-quality research priorities to the Department of Health and Human Services and private funders. Their goal is to ensure that autism policy remains grounded in rigorous scientific data.

Chronic pain affects approximately 16% of autistic children and 65% of children with ADHD. This pain is often nociplastic, meaning it occurs without specific tissue damage, resulting instead from a dysregulated nervous system trapped in a fight-or-flight state.

Sensory sensitivity, difficulties with interoception—the awareness of internal bodily signals—and emotional dysregulation often intensify the experience of pain. When the sympathetic nervous system remains overactive, it lowers the threshold for physical discomfort.

Multidisciplinary programs focus on nervous system regulation and functional restoration rather than just symptom suppression. Caregivers can support children by validating their pain, ensuring quality sleep, and working with schools to provide sensory-regulating tools and quiet spaces.

For elementary students, "Would You Rather" questions reveal personal values through play. Middle schoolers respond better to broad questions about their environment which build trust before parents move to more personal topics.

Active listening and validation are essential when speaking with neurodivergent children. Parents should reflect the child's thoughts back to them to ensure they feel understood, rather than immediately offering unsolicited advice or judgment.

When communicating with teenagers, parents should transition into a coaching role. This involves focusing on the present moment and engaging in collaborative discussions about the future to reduce the strain on the relationship caused by ADHD symptoms.

Research identifies three primary parenting styles: the "Brick Wall" (high control, low warmth), the "Jellyfish" (high warmth, low control), and the "Backbone" (consistent rules with high warmth). Children in "Backbone" families typically demonstrate the highest levels of independence.

Consistent routines reduce anxiety and foster social responsibility. Children with ADHD often struggle in "Jellyfish" environments where a lack of predictable structure can lead to increased stress and difficulty managing daily expectations.

Parents can provide necessary structure by maintaining regular meal and sleep schedules. Visual calendars and verbal preparation for schedule changes help children navigate transitions and understand upcoming expectations.

While medication addresses core ADHD symptoms like hyperactivity, it does not teach executive skills such as planning and organization. These skills must be developed through environmental modifications and consistent practice.

Experts suggest grouping items by their function and assigning every object a specific "home." Placing storage containers in the exact areas where items are used and using clear labels can improve visibility and reduce the frequency of lost items.

Habit-building strategies include setting reminder alarms and defining the end of a task clearly. For example, a student should consider homework finished only after they have placed it back in their backpack and zipped the bag.

Why top scientists are breaking away from the federal government to protect the integrity of autism research.

Find out why treating summer camp like a "vacation marathon" without support might be setting your child up for failure.

Today’s update features the establishment of a science-led autism research committee, criteria for selecting ADHD-friendly summer camps, and a review of educational pathways for students with learning differences (Blog Name: Living on the Spectrum).

The Autism Science Foundation and the Coalition of Autism Scientists established the Independent Autism Coordinating Committee (I-ACC). This group serves as a science-driven alternative to the U.S. federal Interagency Autism Coordinating Committee (IACC).

The committee formed in response to concerns that the official government group lacks sufficient research expertise. Researcher David Mandell stated the I-ACC will propose a high-quality research agenda to guide the Department of Health and Human Services (HHS), private funders, and the broader community.

The I-ACC aims to ensure evidence-based science remains at the forefront of policy and media discourse. Members prioritize scientific data over unsupported theories, such as vaccine-causality myths or ineffective medical procedures like chelation.

Parents should look for programs that minimize unstructured time, as a lack of routine often triggers struggles for children with impulse-control issues. Effective camps provide specific areas where a child can decompress to manage emotional dysregulation.

Successful camp experiences depend on staff who recognize different ADHD profiles, including inattentive and hyperactive/impulsive types. Parents should confirm that counselors understand how to support participation while minimizing screen-based activities.

Experts advise against "medication vacations" because the camp environment requires high levels of focus and impulse control. Using a structured communication letter to detail specific behavioral triggers and successful interventions helps counselors provide better support.

Public, magnet, and charter schools must provide evaluations and support through Individualized Education Plans (IEP) or 504 Plans. While these resources are legally mandated, families often encounter challenges related to large class sizes and limited funding.

Private schools specifically for conditions like Dyslexia, Dysgraphia, and Dyscalculia offer tailored instruction and smaller classes. Parent surveys indicate these environments can significantly reduce student anxiety and improve engagement, though they often require high tuition.

Homeschooling and virtual schools offer flexibility for families needing customized schedules and environments. These options require high parental involvement and may offer fewer social opportunities than traditional school settings.

Your child’s shirt tag irritation might start in their skin rather than their brain.

We examine why standard willpower fails when your internal clock is biologically wired to ignore the future.

Today’s selection for Living on the Spectrum explores the biological roots of sensory sensitivity, the extended neurobiological timeline for ADHD brain development, and practical strategies for fostering independence in young adults.

Neurobiologists Patrik Ernfors and David Ginty received the 2026 Brain Prize for mapping how the body processes touch and pain. Ginty's research specifically identifies that touch overreactivity in some autistic individuals originates in the peripheral nervous system—the nerve network outside the brain and spinal cord—rather than the brain itself.

The researchers used genetic tools to categorize sensory neurons based on gene expression patterns. This work demonstrates how different neurons distinguish between types of tactile information and convert physical contact into neural signals, providing a biological basis for individual differences in sensory processing.

Identifying the peripheral nervous system as a source of sensory distress opens new pathways for therapeutic interventions. Current research explores how targeting these specific nerve pathways might alleviate the physical discomfort associated with tactile hypersensitivity.

Recent mouse model studies show that astrocytes—star-shaped cells in the brain—play a primary role in regulating oxytocin and social interactions. In the hypothalamus, these cells sense oxytocin and signal neurons to produce more of it, creating a positive feedback loop essential for social bonding.

Researchers found that astrocytes in the lateral septum regulate social fear differently across sexes. Male mice have fewer astrocytes and oxytocin receptors in this brain region compared to females, which may account for variations in social anxiety levels and response to social stress.

These findings suggest a biological mechanism for the social challenges often seen in neurodivergent populations. While the research highlights how glial cells modulate emotional states, experts indicate that further studies across larger cohorts are necessary to confirm these patterns in humans.

Young adults with ADHD often reach emotional maturity significantly later than their peers, sometimes not until their late 30s. This delay stems from the frontal lobes—responsible for executive functions like impulse control—continuing to develop until age 35.

Because of this neurobiological delay, the shift from school to the workforce often requires extended family support and specialized coaching. Career counselors who match ADHD strengths to specific roles can help bridge the gap between academic environments and professional expectations.

Building independence requires targeted practice in everyday tasks, such as scheduling appointments or managing laundry. Strategies like role-playing help manage the "internal chatter" that often disrupts focus, while scripts can reduce the anxiety associated with making phone calls or ordering at restaurants.

When adult children move back home, successful "re-launching" depends on clear timelines and financial expectations. Parents can collect rent to be placed in a "launch account" for the child's future while mandating treatment, such as medication or coaching, to ensure the arrangement supports growth rather than dependency.

The ADHD brain often uses optimistic excuses—such as "I'll do it tomorrow" or "It will only take a minute"—to avoid immediate stress. Recognizing these "first dominoes" is the first step toward breaking the cycle of delay and reducing the shame associated with task avoidance.

The "Just Start" strategy involves committing to a dreaded task for only five minutes. This low-pressure entry point helps overcome temporal discounting, where the brain favors immediate ease over future rewards. Labeling the "ugh" feeling of a task can also lower its perceived intensity and help initiate action.

Technology can assist in maintaining momentum by blocking distractions or gamifying focus. Apps like Forest reward phone-free time, while Freedom blocks digital interruptions. These tools help create the "external structure" that many individuals with ADHD need to manage executive function challenges.

Over the last fifty years, Thailand has transitioned from basic academic neuroscience to translational research focused on neurodevelopmental disorders. Current studies emphasize quantitative EEG (qEEG) patterns and melatonin receptor functions as markers for neurological differences.

The Genomics Thailand initiative is identifying genetic variants in rare neurological diseases through the Thai Reference Exome (T-REx). This data allows for more precise modeling of human mutations in platforms using fruit flies and zebrafish, accelerating the screening of potential neurotherapeutics.

Why your brain’s "star-shaped" cells might be the hidden key to understanding social anxiety and autism.

Discover why the most important skill for a college freshman has nothing to do with their GPA.

Today's selection explores the biological mechanisms of social behavior in the brain, practical strategies for managing ADHD and learning disabilities in educational settings, and opportunities for community advocacy in autism research. (Blog Name: Living on the Spectrum)

Research in mice shows that astrocytes, star-shaped glial cells, are essential for regulating oxytocin and driving social behaviors. These cells in the hypothalamus and lateral septum sense oxytocin and signal neurons to produce more. This self-amplifying mechanism, mediated by retinoic acid, suggests that glial cells are finely tuned to neuromodulators that influence emotional states.

One study demonstrated that astrocytes in the lateral septum modulate social fear differently in males and females. These variations may explain differences in social anxiety levels between the sexes. The research points to a new biological perspective on social difficulties, although further studies must determine if these effects persist in larger, more diverse populations.

Nearly one-third of children with ADHD also have a math learning disability (MLD). Weak working memory makes it difficult to memorize math facts or follow multi-step procedures, while slow processing speed often leads to anxiety during timed tests. Executive function deficits also hinder a student's ability to ignore irrelevant information or switch between different operations, such as addition and subtraction.

The ADHD brain habituates quickly to repetitive tasks, leading to "sloppy" errors even after a student has mastered the material. Because ADHD is linked to lower levels of dopamine, students may experience less satisfaction upon completing difficult assignments. This reward deficiency can make persistent effort in math more challenging.

Recommended interventions include using manipulatives, providing explicit instruction in math language, and color-coding salient details. Tools such as multiplication charts can support students with limited working memory, allowing them to focus on higher-level reasoning rather than rote calculation.

High school Individualized Education Programs (IEPs) and 504 Plans do not automatically transfer to college. While high schools may modify the curriculum itself, colleges only offer accommodations that change how a student accesses the curriculum, such as extended testing time.

Students must lead the request for services by self-identifying to the college accessibility office. Necessary steps include preparing neuropsychological testing and medical records, learning the vocabulary of self-advocacy, and initiating outreach to professors. Setting up these resources before they are needed is a demonstration of self-knowledge and strength.

Behavioral interventions serve as a primary treatment for elementary students with ADHD. Teachers can provide external support by greeting students individually, reviewing expectations before starting activities, and offering choices in work methods. Visible timers and illustrated step-by-step plans help students manage internal timing and task completion.

Consequence interventions should focus on guidance rather than discipline. Specific, labeled praise and corrective feedback help students develop self-control. Research indicates that responding to more than half of disruptive behaviors can significantly reduce rule violations over time, especially when students are involved in the problem-solving process.

Effective systems for managing homework include the Binder System, which uses specific "To Do" and "Hand In" sections, and the Accordion System, which uses a 13-pocket folder to separate subjects. Parents can support these systems using the PACK method—Purge, Accessorize, Categorize, and Keep it up—during weekly cleanup sessions.

Analog clocks and visual timers make the abstract concept of time more concrete for students with ADHD. Structured planners help track long-term projects and estimated task durations. At home, a desktop file box for completed units can reduce backpack clutter. While digital tools are available, traditional planners are often more effective for maintaining focus.

The Interagency Autism Coordinating Committee (IACC) has scheduled a full committee meeting for March 19, 2026. The Autistic Self Advocacy Network (ASAN) is urging community members to submit public comments by March 12th to influence how federal money is spent on autism research.

Advocates are encouraged to demand research that focuses on practical supports, affordable housing, and living wages for support workers. Key topics include ending seclusion and restraint in schools and increasing autistic representation on the committee. ASAN emphasizes that research should involve autistic people as active partners through Community-Based Participatory Research (CBPR).

Comments can be submitted via email. For those wishing to remain anonymous, the use of temporary email addresses is recommended. Public comments serve as a direct way for the community to inform the government about specific needs and priorities regarding neurodevelopmental policy.

Your late-night snacking and "wired" brain at midnight might be a biological "doom loop" rather than a lack of willpower.

Discover why your body signals for a metabolic spike just as the rest of the world is shutting down.

Today’s edition of Living on the Spectrum examines the biological mechanics behind ADHD sleep disruptions, the impact of neurodivergent burnout, and significant federal updates to disability civil rights protections.

Research indicates that approximately 80% of individuals with ADHD experience a delayed circadian rhythm. This delayed internal clock often creates a cycle where erratic schedules and nighttime light exposure weaken the central sleep-wake signals. This weakness leads to daytime exhaustion and subsequent naps, which further prevent consistent nighttime sleep.

While blue light from screens is often blamed for insomnia, the emotional engagement of digital content is frequently more disruptive to the ADHD brain. Additionally, eating during the "biological night" interferes with sleep cycles by triggering thyroid-stimulating hormone. This hormonal shift signals the body to increase energy intake, resulting in high-calorie cravings and metabolic spikes that prevent rest.

Clinicians define ADHD-related insomnia as difficulty initiating or maintaining sleep at least three times per week alongside daytime distress. Cognitive Behavioral Therapy for Insomnia (CBT-I) serves as the primary treatment to address the specific mindsets and behaviors that block sleep.

Neurodivergent burnout frequently stems from masking, the habit of hiding autistic or ADHD traits to meet social expectations. This constant effort results in persistent fatigue, chronic pain, and a decline in executive functions like planning and memory. Without intervention, this state can lead to a total inability to maintain career or relationship obligations.

Recovery requires shifting toward authentic self-expression and establishing realistic personal goals. This includes practicing unmasking, such as allowing oneself to stim (repetitive self-stimulatory behaviors) in safe environments. Support from neurodivergent-affirming healthcare professionals—who view neurodivergence as a natural variation rather than a pathology—is essential for effective recovery.

The Department of Health and Human Services (HHS) issued the first update to Section 504 of the Rehabilitation Act in 50 years. The new rule prohibits medical providers from using stereotypes to judge the value of disabled lives. It specifically bans discriminatory value measures like Quality-Adjusted Life Years (QALYs) when determining the cost-effectiveness of medical treatments.

The update mandates that medical equipment and web services meet specific accessibility standards. It also strengthens the "integration mandate," confirming the legal right for disabled individuals to receive services in community settings rather than institutions. New provisions also aim to prevent discrimination against disabled parents and children within the child welfare system.

Nine states—Texas, Florida, Alaska, Indiana, Kansas, Louisiana, Missouri, Montana, and South Dakota—have filed a lawsuit to overturn the 2024 updates to Section 504. The lawsuit specifically targets the integration mandate, which ensures disabled people can live and work in their communities.

The Autistic Self Advocacy Network (ASAN) reports that this lawsuit threatens protections that prevent medical discrimination and ensure accessible equipment in hospitals and schools. ASAN is currently coordinating efforts for residents in the involved states to urge their Governors and Attorneys General to withdraw from the case.

Your trust in scientific breakthroughs might depend on a system where up to 80% of experts are too busy to verify the data.

We look at what happens to the truth when the gatekeepers of science are too overworked to stay on duty.

Today's update examines how the current shortage of expert reviewers in neuroscience threatens the reliability of published research, including studies relevant to the autism community (Blog Name: Living on the Spectrum).

The Transmitter reports that reviewer acceptance rates in neuroscience typically range from 20 to 50 percent. This shortage of experts willing to evaluate research before publication forces journals to rely on a smaller, less diverse pool of scientists.

A lack of robust peer review creates "filter bubbles" where small groups of scientists can introduce bias into the literature. Weak oversight historically contributed to the spread of misinformation, such as the debunked link between vaccines and Autism Spectrum Disorder (ASD). Ensuring a high volume of independent reviewers helps prevent such errors from gaining scientific legitimacy.

Researchers suggest increasing participation by paying reviewers or shifting toward post-publication evaluation on community platforms like PubPeer. While artificial intelligence is often discussed as a solution, large language models cannot replace the human reasoning required to analyze novel findings. The community needs human expertise to maintain the robustness of neurodevelopmental research.

A 24-hour window during pregnancy may explain why male fetuses are uniquely vulnerable to a mother’s immune response.

Discover how a common infection can trigger an internal "border conflict" that alters a child’s development before birth.

Living on the Spectrum: Today's update examines how maternal immune responses during pregnancy interact with placental cells to influence male fetal development.

Infection during pregnancy triggers immediate changes in spongiotrophoblasts, which are placental cells forming the barrier between maternal and fetal environments. This reaction compromises maternal immune tolerance and leads to inflammation. Male offspring in the study subsequently displayed autism-associated behaviors, including repetitive actions and social deficits.

Male fetuses show higher vulnerability to these immune changes due to Y-chromosome-encoded antigens and a reduction in immunosuppression at the maternal-fetal interface. Within 24 hours of maternal immune activation, affected males exhibited structural disruption in the placenta. Researchers also measured elevated levels of the signaling protein IL-6 in the amniotic fluid, a cytokine previously linked to autism-related behaviors.

The study indicates that the "placentological" environment serves as a driver for neurodevelopmental conditions. These behavioral differences arise from factors external to the brain itself. Findings also show that the sex of neighboring fetuses in the womb influences the probability of these developmental changes, highlighting the role of the immediate uterine environment.

Your "little brain" does more than keep you balanced; it is a powerhouse for processing human language and meaning.

New research into these hidden biological circuits is fundamentally redefining our view of neurodiversity.

Today’s selection covers shifting trends in autism diagnosis by sex, new findings on how the cerebellum processes language, and the role of placental immunity in neurodevelopment (Blog Name: Living on the Spectrum).

A study of nearly 3 million children in Sweden indicates that the sex ratio in autism changes as individuals age. Boys are three times more likely than girls to receive a diagnosis before age 10, but this gap narrows to a 1.2-to-1 ratio by age 20. The ratio is also notably lower when autism co-occurs with an intellectual disability.

Researchers suggest many girls go undiagnosed in early childhood because they often present different traits, such as stronger language skills or consistent eye contact. Many also use masking to hide social difficulties. As social expectations become more complex during adolescence, these traits become more apparent, leading to later identification.

A study using fMRI found that specific regions of the cerebellum show language selectivity similar to the brain's cortex. Researchers identified four cerebellar areas responsive to language, including one highly tuned to meaningful sentences. This region showed lower activation for meaningless "jabberwocky" sentences compared to the neocortex, suggesting it is specifically focused on processing meaning.

The research team noted that pediatric injuries to the cerebellum often result in significant speech deficits. This suggests the cerebellum is an integral part of the broader language network. While some researchers point out that fMRI cannot easily distinguish local cerebellar work from cortical inputs, the findings emphasize the need to include this brain region in studies of language acquisition.

Infection during pregnancy can trigger an immune conflict in the placenta that affects fetal development. Researchers using a synthetic compound to mimic viral infection found that maternal immune activation causes structural changes in placental cells. These changes lead to an accumulation of inflammatory proteins, specifically IL-6, in the amniotic fluid.

The study observed autism-related behaviors, such as social deficits and repetitive actions, only in adult male mice. Researchers suggest this sex bias may stem from the maternal immune system recognizing Y-chromosome-encoded antigens as foreign. This finding shifts focus toward immunological and placental drivers of neurodevelopmental conditions rather than focusing solely on the brain.

Neuroscience research is moving toward analyzing individual synapses rather than large populations. Synapses vary in protein levels and architecture, creating a diverse "synaptome" that changes throughout a person's life. This diversity suggests that learning may be encoded by the distribution of specific synapse types.

Nearly 1,000 genes linked to neurodevelopmental differences affect only specific subsets of synapses at different locations and ages. Researchers argue that advancing single-synapse physiology is necessary to understand these distinct pathologies. This approach could lead to targeted strategies to restore specific synapse types affected by these conditions.

Neuroscientist Ishmail Abdus-Saboor highlighted a study identifying sensory neurons (MRGPRB4-positive C fibres) that detect pleasurable, massage-like stroking. Using calcium imaging and behavioral tests, researchers proved that stimulating these neurons produces a positive response in animals.

This discovery established a biological basis for positive sensory perception. Current research builds on this by examining how these neurons influence social touch and sensory processing. Understanding these circuits provides insight into naturally occurring social behaviors like bonding and interaction.

Sam Wang, a Princeton University neuroscientist known for research on the cerebellum and autism, is running for the U.S. House of Representatives. His platform includes protecting research funding and addressing federal public health policies. Wang also co-founded BlinkLab, a company using AI to detect early signs of autism through smartphone-based sensory tests.

Supporters suggest that having a scientist in Congress could ensure that autism policies remain evidence-based. A scientific background may also provide a check on federal executive control over research committees. Other experts note that the scientific community must continue communicating the value of research to all legislators, regardless of their professional backgrounds.

The placenta may act as a selective gatekeeper, responding to maternal infections in ways that specifically impact male neurodevelopment.

The conversation shifts from the microscopic environment of the womb to the legal frameworks that determine who gets support.

Today's highlights explore how maternal immune responses during pregnancy may affect fetal development via the placenta and introduce a new toolkit for navigating Medicaid advocacy (Blog Name: Living on the Spectrum).

The Transmitter reported that maternal immune activation triggers an immune conflict in the placenta that specifically affects male fetal development in mice. Researchers used a viral-mimic compound called poly I:C to observe how infections during pregnancy lead to autism-related behaviors in male offspring. The study indicates that the placenta plays a primary role in these neurodevelopmental changes.

Infection on embryonic day 12.5 causes structural disorganization and inflammatory gene upregulation in spongiotrophoblasts. These cells normally form the barrier between the maternal and fetal parts of the placenta. This disruption causes a loss of immunosuppression, which allows immune signaling proteins like IL-6 to accumulate in the amniotic fluid of male fetuses.

Male-specific vulnerability may stem from Y-chromosome-encoded antigens that the mother's immune system recognizes as foreign. The sex of neighboring fetuses in the womb also influences the level of risk. These findings suggest that researchers should investigate placental drivers alongside internal brain factors to understand the origins of neurodevelopmental conditions.

The Autistic Self Advocacy Network (ASAN) released "Making the Most of Medicaid: a Medicaid 1115 Waiver Advocacy Toolkit." This guide helps individuals understand 1115 waivers, which are provisions allowing states to test different ways to deliver and pay for Medicaid services outside of standard federal rules. The toolkit aims to empower the community to influence how these programs operate at the state level.

The toolkit provides instructions on navigating complex healthcare regulations and identifies specific ways to advocate for program improvements. It simplifies the significance of waivers so that users can effectively communicate with state officials. Community members can use these resources to identify gaps in current state services and propose changes.

This resource serves Medicaid recipients, their support networks, and healthcare professionals working within the system. It focuses on the United States healthcare landscape, specifically targeting state-level policy changes. The guide acts as a bridge between federal policy and local service implementation for neurodivergent individuals.

What happens when a Princeton neuroscientist trades his lab for a seat in Congress to fix how the government funds autism research?

The path to scientific progress is finally meeting its ethical reckoning in the halls of power.

Today’s coverage explores the intersection of neurodevelopmental science and public policy, from a neuroscientist's bid for Congress to the ethical reckoning of historical brain research (Blog Name: Living on the Spectrum).

Sam Wang, a Princeton neuroscientist and co-founder of the AI-driven autism detection company BlinkLab, has announced his candidacy for the U.S. House of Representatives. Wang’s decision follows recent federal funding cuts and shifts in public health policy, specifically the overhaul of the Interagency Autism Coordinating Committee (IACC). Psychiatry resident Zachary Williams suggests that a representative with specific autism expertise could help shift government focus toward evidence-based policy and provide a necessary check on executive control over scientific agencies.

Wang’s academic work identifies the cerebellum as a key brain region in autism, a research focus influenced by his personal experience growing up with an autistic sister. While some former officials, such as Walter Koroshetz, argue that effective science advocacy does not strictly require a scientific background, supporters highlight Wang’s ability to mobilize the academic community.

Beyond neurodevelopmental policy, Wang intends to apply his data-driven background to systemic political issues. His platform includes addressing gerrymandering by analyzing district line patterns and pursuing reforms for the Electoral College.

Neuroanatomist Paul I. Yakovlev amassed a collection of over 1,000 human brains sourced from residents of state institutions, including the Walter E. Fernald State School for individuals with developmental disabilities. Using a specialized microtome, Yakovlev created 250,000 tissue slides to investigate the mechanical origins of neurological disorders. This work took place during the eugenics movement, a period when institutionalized individuals were frequently treated as biological specimens rather than patients.

Disability justice advocate Alex Green argues that the Yakovlev collection represents a systemic dehumanization of people with neurodevelopmental differences. While Yakovlev framed his work as a scientific endeavor, the lack of individual agency for those in the collection highlights the ethical failures of historical medical research. Some scholars now view the collection more as a historical warning regarding medical ethics than a source of modern scientific breakthrough.

Following a 2025 change in Massachusetts law, archives from these state institutions are now open to the public. This allows families and researchers to reconstruct the personal biographies of individuals previously reduced to medical data. Current institutions, such as the Harvard Brain Tissue Resource Center, continue neurological research but operate under strict modern consent protocols that contrast with the practices of Yakovlev’s era.
