Brain Tracks Two Conversations at Once, Study Finds
EEG research from Trinity College Dublin reveals a 1–2 second 'dual tracking' window where the brain processes two conversations simultaneously before switching focus.
Human Brain Organoids Restore Circuits in Cortex-Depleted Mice
Stanford researchers transplanted lab-grown human brain organoids into mice engineered without most of their cerebral cortex, forming functional neural circuits that influenced motor behavior.
Brain Stem Network Mapping May Lead to Targeted PTSD Therapies
A new study combines rodent circuit mapping with 7T human fMRI to identify how the brain controls the periaqueductal gray, aiming to develop real-time neurofeedback for PTSD and anxiety.
Brain Scans Reveal Synaptic Loss Starts in Left Frontal Lobe in Schizophrenia
PET imaging of 122 people found widespread synaptic loss in schizophrenia, starting in the left frontal lobe and following the brain's neurotransmitter blueprint, separate from MRI volume changes.
New Alzheimer's Drug Diranersen Lowers Tau and Slows Memory Loss
Biogen's diranersen cut tau levels by up to 65% and slowed cognitive decline versus placebo in a Phase II trial—but the biggest tau reductions didn't produce the best cognitive outcomes.
Entropy Measures Reveal How Brain Regions Communicate During Tasks
New research uses information theory to map brain connectivity during motor, memory, emotion, and language tasks—without pre-existing models.
Infants Learn Which Arm Moves the Mobile: A Computational Model
A new computational model reproduces how infants learn to move the limb connected to a crib mobile, revealing four mechanisms behind early sensorimotor learning.
Brain Genome Regulation Shifts Sharply Between Ages 50 and 75
A single-cell study of the human hippocampus finds microglia replacement, blood-brain barrier decline, and 3D genome disorganization beginning in midlife.
Cerebellum and Sensorimotor Cortex Shape Visual Attention and Anxiety
A new neuroimaging study finds that greater grey matter in cerebellar lobule VI and thicker sensorimotor cortex predict more flexible visual attention, especially in people with lower trait anxiety.
Brain Activity Predicts Risky Choices 500 ms Before You Act
Direct recordings in the human orbitofrontal cortex reveal two opposing neural circuits that forecast risky vs. safe choices half a second before action.
Disadvantaged Neighborhoods Linked to Accelerated Brain Aging
A study of 2,826 brain MRIs links neighborhood socioeconomic disadvantage to older-looking brains, reduced volume, and vascular white matter damage.
Study Maps the 9 Distinct Types of Procrastinators
A University of Cambridge social scientist synthesizes hundreds of studies to identify 9 procrastinator archetypes—and explains why chronic delay harms your brain, health, and finances.
