NeuroCogMap Reveals Cognitive Organization in AI and Predicts Human Brain Activity
A new framework, NeuroCogMap, organizes internal features of large language models (LLMs) into functional parcels, revealing cognitive organization and links to human brain activity.
Speaking 4 Languages Makes Your Brain Appear 13 Years Younger
A new study using AI and brain scans found that speaking two, three, or four languages correlates with brains appearing 6, 7, and 13 years younger than chronological age.
Biomarkers Boost Antidepressant Success Rates by 67%
A new study shows that using fMRI brain scans and cognitive tests to match patients to antidepressants increases response rates by nearly 67%, moving psychiatry toward precision medicine.
Mice Use Strategic Infotaxis to Overcome Poor Vision
A new study from EPFL shows that mice actively use visual infotaxis—moving strategically to maximize information gain—to identify partially hidden objects, revealing that even poor-sighted rodents rely on internal models of space.
Maternal Vocal Response Speed at 12 Months Predicts ADHD Risk
Slower maternal vocal responses to one-year-old infants are linked to higher ADHD and disruptive behavior disorder odds by age 7, new PLOS One study finds.
How the Brain's Visual Cortex Enables Flexible Thinking
A new study reveals a specific brain circuit that allows higher cognitive areas to reshape early visual processing, enabling flexible rule-switching.
Lab-Grown Eye Vessel Cells Regenerate Retina, Restore Vision
Researchers at Duke University have grown rare retinal endothelial cells from stem cells, which regenerated damaged blood vessels and restored vision in mice.
Wearable BCI Detects Hidden Consciousness in Brain-Injured Patients
New research using a wearable EEG headset with real-time auditory feedback nearly doubles detection of hidden consciousness in unresponsive patients, from 39% to 69%.
Cognitive Training Boosts Cognition and Mood in Brain Tumor Patients
A new trial shows that multidimensional cognitive training improves cognition, mood, and quality of life in postoperative glioma patients.
Can Creatine Boost Depression Treatment? Mixed Results for a Surprising Supplement
A new systematic review finds creatine accelerates remission in women with depression but fails in teens and bipolar patients, with some risks.
Meta-Learning Makes AI Visual Representations More Human-Like
Meta-learning, or learning to learn, helps AI models develop visual representations that better match human similarity judgments and brain activity.
New AI method combines brain data across individuals for clearer insights
Researchers introduce DPMS, a machine learning framework that integrates whole-brain neural recordings from multiple individuals, improving models of brain activity beyond single-subject analyses.
