First Brain Map of Histamine System Links Molecule to ADHD and Depression
Researchers created the first multiscale map of the brain's histamine system, revealing its role in ADHD, depression, and schizophrenia.
How Circadian Rhythm Disruption Turns Brain Clean-Up Cells Against You
Dysregulated sleep-wake cycles can turn microglia from protectors into malfunctioning cells that fail to clear amyloid plaques, accelerating dementia risk. A new EV therapy aims to prevent this shift.
New Tools Map Millions of Aging Brain Cells, Reveal Inflammatory Hotspots
Researchers developed IRISeq and EnrichSci to map millions of aging brain cells, revealing inflammatory clusters in white matter and ventricle-specific inflammation.
Cerebellum-Inspired Module Boosts Neural Network Temporal Learning
Researchers augmented RNNs with a cerebellar-like feedforward module, achieving faster learning and higher performance on temporal tasks compared to standard recurrent networks.
Homological Brain: How Your Brain Turns Complex Searches into Simple Navigation
The Homological Brain framework uses topology to explain how the brain transforms slow, complex searches into fast, automatic navigation via 'topological condensation.'
GLP-1 Drugs Quiet 'Food Noise' Better Than Therapy Alone, Study Shows
New research finds GLP-1 medications dramatically reduce intrusive food thoughts—far more than behavioral therapy alone—offering a neurobiological explanation for their weight loss success.
How the Brain Preserves Memories While Adapting to New Contexts
New research identifies joint sparse coding and temporal dynamics as key mechanisms that help the brain retain prior knowledge while flexibly adapting to new contexts.
Brain-Controlled Hearing Aid Solves Cocktail Party Problem
Columbia researchers developed a real-time brain-controlled hearing system that amplifies a chosen voice in a crowd, offering a breakthrough for hearing aids.
Bipolar Disorder's Cognitive Decline Linked to Insulin Resistance
New research identifies a specific pathway where insulin resistance leads to gray matter loss and cognitive impairment in bipolar disorder patients, offering potential for targeted treatments like GLP-1 agonists.
Predictive vs. Feedback Signals in Language Learning: fMRI Study
New fMRI study reveals predictive signals drive group-level language learning, while feedback signals explain individual differences.
Brain stimulation cuts procrastination by boosting reward valuation, not reducing task dread
New research shows stimulating the left DLPFC with HD-tDCS reduces real-world procrastination for up to 6 months by increasing perceived value of task outcomes.
Visceral Fat Drives Brain Atrophy; Glucose Control Is Key
A 16-year MRI study of 533 people found that sustained lower visceral fat, mediated by glucose control, preserves brain volume and cognitive function in late midlife—independent of weight loss.
