Feature Visualization Reveals How AI Models Match Brain Visual Areas
New research shows that feature visualization can recover known brain selectivity from AI encoder models, revealing progression from V1 to higher areas.
How RNNs Switch Brain Rhythms: Multiple Mechanisms Revealed
A new study shows that neural networks use multiple strategies—population turnover, baseline shifts, and phase reorganization—to switch between brain rhythms like theta, alpha, beta, and gamma.
Harsh Parenting Disrupts Child Stress Regulation, Study Finds
New research shows that harsh parenting alters children's biological stress regulation, making them more dependent on external regulation as they grow.
Why 90% of People Are Right-Handed: Bipedalism and Brain Growth
New research links human right-handedness to bipedalism and brain expansion, solving an evolutionary puzzle.
Consciousness as Uncommon Self-Knowledge: A Synergistic Information Theory
New theory proposes consciousness is synergistic self-information that disappears when you break a system apart, separating it from metacognition.
Childhood Adversity Blunts the Social Benefits of Intelligence
New research shows that higher IQ does not equally boost trust for everyone: childhood disadvantage cuts the effect of intelligence on social trust in half.
How Visual Cortex Neurons Organize Synaptic Inputs: Key Rules Discovered
MIT neuroscientists discovered three rules governing how visual cortex neurons organize thousands of synaptic inputs, revealing distance, clustering, and orientation selectivity shape brain wiring.
Brain-Stimulating Contact Lenses Show Promise Against Depression in Mice
New contact lenses deliver mild electrical signals to the brain via the retina, restoring connectivity and raising serotonin levels by 47% in mice — matching the effects of Prozac.
Your "Um" and Pauses Could Reveal Early Dementia Risk
New research shows that subtle speech habits like pauses and filler words are linked to executive function, and AI can predict cognitive performance from natural conversation.
Behavioral Geometric Supervision Aligns Video Models with Human Social Perception
A new method called behavioral geometric supervision (BGS) uses human odd-one-out judgments to train video AI models to perceive social interactions like humans do.
APOE2 Gene Protects Neurons by Repairing DNA Damage, New Study Finds
Buck Institute researchers discovered that the APOE2 gene variant helps neurons repair DNA and resist aging, offering a new target for Alzheimer's therapies.
Moderate Coffee Intake Linked to 35% Lower Dementia Risk
A 43-year study of 131,821 people found that 2-3 cups of coffee daily reduced dementia risk by 35% in those under 75, with benefits leveling off at higher intake.
