🧠 A new study by the University of Cambridge offers a detailed model of human brain development from mid-pregnancy to early infancy, revealing distinct growth patterns for different tissues and sex-based differences in brain volume.

📈 The research, analyzing 798 MRI scans from 699 individuals (263 fetuses, 535 newborns), found that white matter growth dominates mid-pregnancy, shifting to gray matter in late pregnancy and infancy, with subcortical regions maturing earlier than the cortex.

👦👧 Males, on average, showed greater increases in brain volume than females across the studied period (21 to 45 weeks gestation), with some regional differences noted, suggesting biological factors during pregnancy initiate these divergence patterns.

🧠 New research in NeuroImage links increased social media use in young adolescents (ages 10-13) to physical brain differences, specifically a thinner outer brain layer in areas crucial for attention, memory, and emotional control.

🔬 The study analyzed data from 7,614 children using structural MRI scans and found that higher average daily social media use correlated with reduced cortical thickness across several brain regions.

🤔 Researchers caution that while these physical differences are statistically significant, their size is comparable to effects from reading or watching TV, and the study cannot definitively prove causation – meaning it's unclear if social media causes these brain changes or if pre-existing differences lead to more social media use.

🧠 Study of over 11,000 teens (ages 9-17) found that starting cannabis use is linked to slower development in memory, attention, and thinking speed over time.

📈 Over time, THC exposure was associated with worse memory development in teens during critical brain development years.

🔬 Researchers from UC San Diego School of Medicine analyzed data from the Adolescent Brain Cognitive Development (ABCD) Study, published April 20, 2026.

👶 Mount Sinai study reveals early-life metal exposures during specific weeks in infancy (weeks 4–8 and 32–42 after birth) are linked to behavioral challenges and measurable differences in adolescent brain development and communication.

🦷 Researchers used baby teeth as a biological record to reconstruct weekly metal exposure from pregnancy through the first year of life, linking it to later brain scans and behavioral assessments in 489 children.

🧠 Higher metal mixture exposure during these critical windows was associated with increased behavioral symptoms like anxiety, attention issues, and mood challenges, with about 4% of children showing clinically significant scores.

💡 Findings emphasize the importance of environmental protections for pregnant people and infants, suggesting that focused policies reducing metal exposure during specific high-risk windows could have lifelong benefits for brain health.

🧠 New study in Nature Neuroscience reveals shifting glucose levels act as a "metabolic switch" regulating oligodendrocyte progenitor cell (OPC) division and maturation for myelin formation.

🔬 Researchers at CUNY ASRC used MALDI imaging in mice, finding that high glucose regions correlate with increased OPC proliferation, while low glucose areas show cells differentiating into myelin-producing oligodendrocytes.

💡 Glucose acts as a signal for cell division; high levels drive proliferation, and shifts prompt maturation. An enzyme called ATP-citrate lyase (ACLY) is crucial for this process by facilitating histone acetylation and gene activation for proliferation.

🌟 Deleting ACLY in OPCs impaired proliferation, but a ketogenic diet improved myelin deficits, highlighting metabolic flexibility. This research, relevant to human gestation (32-40 weeks), could inform strategies to protect developing brains and repair myelin in conditions like multiple sclerosis.

🧠 New study in mice reveals dopamine receptors on support cells act as "traffic signals" for migrating neurons, slowing them down to reach correct destinations. Disruptions to this signaling early on could permanently alter brain wiring.

🔬 Researchers found that removing dopamine receptors from stationary cortex cells caused migrating neurons to speed up significantly, overshooting their targets and leading to abnormal brain structure in adult mice.

📉 In mice lacking D1 dopamine receptors entirely, the cerebral cortex volume shrank by about a quarter, demonstrating the critical role of dopamine signaling in early brain development.

🧠 ADHD Brain Development Linked to Symptom Paths: New research published in Nature Mental Health reveals that distinct brain development patterns during adolescence physically reflect different ADHD symptom trajectories.

🧠 Brain Scans Show Predictive Power: A study of 7,436 adolescents found that specific rates of brain region thinning and growth could predict future ADHD symptom changes, improving prediction accuracy beyond behavioral checklists alone.

🧠 Medication's Long-Term Impact Unclear: Initial findings suggest that prescribed ADHD medication may not significantly alter the underlying physical brain development pathways linked to symptom remission over the long term.

🧠 Teen Cannabis Use Linked to Brain Differences: A new study found that repeated cannabis use in adolescents is associated with changes in brain areas crucial for motivation and reward.

📉 Dopamine System Impact: Researchers observed reduced dopamine-related activity in teens who used cannabis, with higher-potency products showing stronger effects, suggesting interference with the brain's reward system during a critical development period.

🔬 Study Details: The study, published in Neuropsychopharmacology and funded by the National Institute on Drug Abuse, involved 81 participants aged 14-17 and used MRI to measure tissue iron, an indicator of dopamine system health.

A review of 73 studies has highlighted growing evidence that diet in the early years of life may shape how well the brain develops: “A poorer diet in the first years of life was linked to lower intelligence years later, in adolescence”

🧠 Early life diet significantly impacts adolescent intelligence, with poorer nutrition in infancy linked to lower cognitive function years later.

🔬 A Swansea University review of 73 studies suggests foundational brain health is established very early, even impacting development after other influences are considered.

💡 While adolescence is a period of brain change, evidence on nutritional interventions during this time is mixed, requiring more research to determine if it's a "second window of opportunity."

🌡️ A study by ISGlobal found that heat exposure during pregnancy and early infancy is linked to slower growth of the thalamus, a key brain region for information processing, in children.

🧠 The thalamus, the brain's main relay center, showed a consistent association with early-life heat exposure. This region is thought to be particularly vulnerable due to its early development and rich blood supply.

👶 A critical window for this impact is from conception to the fifth month of life. Exposure to monthly average temperatures of 20.5°C during this period was associated with slower thalamic growth later in childhood.
