How Cortical Geometry, Wiring, and Function Can Supercharge Recurrent Neural Networks
Using data from 12,000 neurons, researchers built brain-like networks that learn faster and organize like real cortex.
Why Severely Stressed Students Are Turning to AI for Therapy
New research shows 18% of college students use generative AI for mental health, with double the usage among those with severe anxiety, depression, or suicidality.
Attention Networks Predict Adult Language Learning Success
New research shows that baseline organization of attention and cognitive control networks, not classic language areas, predicts how quickly and well adults learn a new language.
Saliva Test Reveals 10 Biomarkers of Sleep Deprivation
Researchers identified a 10-biomarker signature in saliva that accurately detects acute sleep deprivation, paving the way for a rapid fatigue test similar to a breathalyzer.
Psilocybin Temporarily Restores Speech and Movement in Advanced Alzheimer’s Patient
A new case report shows that a single dose of psilocybin temporarily restored speech, motor independence, and bladder control in an 80-year-old woman with advanced Alzheimer’s disease.
Brain’s Navigation System Emerges from Simple Learning Rules
New research shows that the brain's ability to anticipate movement and track location can arise naturally from basic learning mechanisms, without needing pre-wired circuits.
Social Inequality Accelerates Biological Aging, Landmark Study Shows
A massive synthesis of 140 studies proves that poverty and racism leave chemical marks on DNA, speeding up biological aging from early childhood.
Concussion Turns Brain's Immune Stabilizer Into a Destroyer
A new study reveals that after a concussion, the brain's own immune receptor TLR4 triggers an enzyme that degrades neural scaffolding, causing long-term memory loss and cognitive noise.
Fusing Amplitude and Phase of fMRI Signals Improves Brain Disorder Detection
A multi-scale fusion learning framework combining amplitude and phase fMRI features outperforms existing methods in classifying autism and depression.
Teen Substance Use Linked to Low Dopamine, Not High Risk-Taking Drive
A University of Pittsburgh study of over 800 teens found that early substance experimentation is driven by low baseline dopamine, not an excess—overturning decades of belief.
Two Hours of Social Media Linked to Teen Depression
A decade-long study of nearly 1,200 teens found that two or more hours of daily social media use predicts increased depressive symptoms and lower well-being one year later, especially in early adolescent girls.
EEG Criticality Accurately Identifies Deep Sleep for Neurofeedback
New research shows that brain signal criticality features can identify deep sleep (N3) with 87% accuracy, enabling passive BCI neurofeedback to enhance cognitive recovery.
