Long-Term Depression Reverses Brain Network Connectivity
New research shows that depression lasting over 24 months flips the connection between executive and introspective brain networks, worsening symptoms.
How attractor networks emerge from the free energy principle
Researchers show that attractor neural networks naturally emerge from the free energy principle, favoring orthogonalized patterns for efficient learning and inference.
Broken Sleep Rhythms: The Glymphatic Link to Dementia
A new study proposes that stress, depression, aging, and heart disease all increase dementia risk by disrupting a sleep-dependent brain rhythm that clears toxic proteins.
Personalized Machine Learning Lifestyle Coaching Doubles Depression Remission Rates
A clinical trial using smartwatch data and machine learning to personalize lifestyle coaching achieved a 55% depression remission rate, nearly doubling standard therapy outcomes.
Structured Lifestyle Programs Slow Biological Aging, Study Finds
A major clinical trial shows that structured, multi-domain lifestyle interventions with coaching and accountability significantly reduce biological frailty and protect cognitive function.
Large Rewards Accelerate Learning by Extending Dopamine Signals
Bigger rewards don't just feel better—they physically lengthen dopamine signals in the brain, enabling faster skill acquisition with fewer repetitions.
Why Alzheimer's Risk Hits Women Harder: New Study on Sex Differences
A UC San Diego study of over 17,000 adults found that common dementia risk factors, like hypertension and obesity, damage women's brains more strongly than men's, suggesting tailored prevention could reduce Alzheimer's.
How Instruction-Tuned AI Models Reveal Brain-Aligned Task Representations During Movie Watching
Study finds instruction-tuned multimodal LLMs align with brain activity better than non-tuned models, suggesting task-specific representations in the brain.
Hidden Alzheimer’s Trigger IDOL: New Enzyme Target Could Clear Plaques
Scientists at Indiana University discovered that removing an enzyme called IDOL from neurons reduces amyloid plaques and may help the brain resist Alzheimer’s damage.
Quantum Physics Equations Used to Map How Emotions Distort Memories
Researchers use quantum formalism to model how emotional events warp the order and precision of memories, explaining why some moments remain sharp while others slip out of sequence.
Real-Time Memory Test Predicts Alcohol Blackouts While Drinking
A new 15-minute memory test can spot alcohol-induced blackouts as they happen, allowing friends to intervene before harm occurs.
Severe CHD8 Mutations Overcome Female Autism Shield
First direct evidence shows that severe genetic mutations can override the natural biological protection females have against autism spectrum disorder, causing pronounced abnormalities in both sexes.
