Sleep Deprivation Boosts Synaptic Density in Key Brain Regions
A new PET imaging study finds that 28 hours of sleep deprivation increases synaptic density markers in the hippocampus and thalamus, supporting the theory that sleep resets neural connections.
Frontal Cortex Maps Visual and Auditory Attention as Traffic Controller
Direct brain recordings reveal the frontal cortex acts as an internal traffic controller, dynamically shifting attention between sight and sound depending on language comprehension.
Cognitive Training vs Aerobic Exercise: Different Brain Benefits
New research shows that cognitive training and aerobic exercise affect older adults' brain structure differently—one boosts gray matter volume, the other increases brain connectivity.
How Human-Like Memory Limits Help AI Learn Grammar Better
Giving AI models a human-like fleeting memory — including a 3-7 word echoic buffer — improves grammar learning by forcing focus on abstract rules rather than literal words.
First Embryonic Stem Cell Trial for Huntington's Opens
UCI Health launches the world's first in-human trial using embryonic stem cell-derived neural stem cells to treat Huntington's disease, with initial safety results promising.
Sleep Habits Determines Whether Your Genes Accelerate Alzheimer's
New research shows that specific AQP4 gene variants interact with poor sleep to accelerate grey matter loss and alter cognitive function, highlighting a modifiable pathway for personalized Alzheimer's prevention.
Trauma Therapy Reverses PTSD in Psychosis Patients: Largest Trial Shows Safety and Effectiveness
A new study finds that integrated Trauma-Focused CBT for psychosis eliminates PTSD in 50% of patients, with low disengagement and broad cognitive improvements.
Network Mapping Uncovers 641 Hidden Schizophrenia Risk Genes
Scientists used long-range co-expression networking to identify 641 novel schizophrenia risk genes, moving toward network-based precision psychiatry.
Ancient Brainstem Circuit Found to Control Selective Attention
Researchers discover a brainstem inhibitory circuit that acts as an attentional selection engine, conserved across vertebrates, with implications for ADHD and autism.
AI and Human Brains Use Same Predictive Language Processing Principles
A new neuroimaging study shows that the human brain and large language models predict words using similar parallel processing strategies, opening doors for brain-computer interfaces and cognitive diagnostics.
Autism Mutations Converge on Shared Early Brain Pathways, Study Finds
Hundreds of diverse autism-linked genetic mutations converge on the same brain cell types and pathways during early development, revealing a critical window for intervention.
OLE Molecule Reprograms Brain Immune Cells to Fight Alzheimer's
A molecule called OLE restores microglia's protective function, reducing plaques and improving memory in Alzheimer's models.
