Bilingual Brains Store Words on One Shared Map, Study Finds
A study of four bilingual epilepsy patients found the hippocampus stores concepts on a single shared map, using language-specific neurons to switch between English and Spanish.
Iron Buildup Strips Neurons of Resilience, Salk Study Finds
Salk researchers engineered the first model of long-term iron accumulation in neurons, naming the progressive pathway "chronoferroptosis" and showing it depletes antioxidant defenses over time.
Hearts Beat Together Within 20 Meters, Study Finds
A study of 72 students in New York City found heart rates synchronize within 20 meters and during shared attention, offering a real-world marker of social engagement.
Comfort Food Shuts Down Chronic Stress Via New Brain Circuit
Scientists mapped a neural circuit from the prefrontal cortex to the hypothalamus that explains how palatable food calms chronic stress by releasing dopamine and suppressing overactive stress neurons.
Brain Handles Surprises Like an Internal Software Update
University of Sydney researchers found the brain uses a dual strategy: it primes fast responses for predictable events and directs rich sensory processing toward surprises, all within milliseconds.
Brain Structure-Function Harmony Declines as Infants Grow
New research tracks structural-functional module consistency in infants, showing a decline from 0 to 5 years, highlighting dynamic brain development.
Tubulin Helps Redirect Alzheimer's & Parkinson's Proteins
Tubulin can redirect Tau and alpha-synuclein from forming toxic clumps to healthy roles, offering a new approach to tackling Alzheimer's and Parkinson's.
Crows Can Do Statistical Reasoning: What It Reveals About Human Math Smarts
Crows can assess odds and choose favorable options, a skill tied to statistical reasoning, shedding light on how human brains process numbers.
Virtual Brain Training: Simulator Improves Neurofeedback Design
New framework simulates decoded neurofeedback to reveal why it sometimes fails and how to test brain-training protocols virtually before human trials.
Early Statin Use After Diabetes Diagnosis Linked to 15% Lower Dementia Risk
Starting statins within a year of type 2 diabetes diagnosis was associated with a 15% lower relative risk of dementia over 10 years, according to a large Danish study.
Probiotics Show Promise for Easing Late-Life Depression
A pilot trial found that adding daily probiotics to standard care modestly reduced depressive and anxiety symptoms in older adults with moderate depression, supporting the gut-brain connection.
Hybrid Neuron Models: Blending AI with Biophysics to Decode Brain Signals
Researchers at Tübingen created a hybrid model merging neural ODEs with biophysical neurons, accurately capturing ion channel dynamics and reducing cortical neuron simulation costs.
