IISc Launches Rs 2 Crore AI Challenge for Early Cognitive Decline Detection
IISc's Centre for Brain Research has launched a Rs 2 crore AI challenge to detect early signs of cognitive decline, aiming to develop accessible screening tools for Alzheimer's and dementia.
Embryonic Pathway Balances Learning and Flexibility in Adults
A receptor that shapes the brain in the womb also tunes learning and flexibility in adults by controlling dopamine and acetylcholine timing.
Toddlers’ Pretend Play Linked to Better Mental Health Later
A study of 1,400 children finds that strong pretend play ability at ages 2-3 predicts fewer emotional and behavioral difficulties at ages 4-7.
Midlife Fitness Delays Chronic Disease by Over a Year, New Study Shows
A study of 24,500 adults finds that being fit in middle age delays chronic illness by at least 1.5 years, extending health span—not just lifespan.
Midlife Hobbies Outperform Genetic Alzheimer's Risk, Study Finds
A 10-year longitudinal study shows that diverse social, physical, and intellectual activities in midlife can outweigh the APOE ε4 gene, the strongest genetic risk factor for late-onset Alzheimer's.
Alzheimer's Brains Share a Genetic Signature with Some Cancers
Alzheimer's disease may be driven by cancer-like mutations in brain immune cells, suggesting existing cancer drugs could be repurposed for treatment.
NeuroAI: Why AI Needs to Learn from the Brain to Overcome Its Biggest Weaknesses
A new NSF report identifies three critical gaps in AI— interaction, learning efficiency, and energy use— and proposes neuroscience-inspired solutions.
Inverted U-Shape Links Amyloid-β to Brain Networks in Cognitively Normal Older Adults
New research with 968 community-dwelling older adults reveals non-linear associations between amyloid-β and functional connectivity, with cognitive performance linked to specific networks.
Brain Criticality Follows Anatomical Hierarchy, Study Shows
Neuronal criticality signatures vary systematically along the brain's anatomical hierarchy, with static and dynamic exponents pointing in opposite directions, linking structure and dynamics.
Chaotic Heartbeats Reveal Hidden Brain Activity
New research shows that the chaotic fluctuations in your heartbeat are uniquely sensitive to mental effort, offering a non-invasive window into brain activity that traditional heart rate measures miss.
Scientists Crack the Molecular Code of Gut-Brain Communication
Neuroscientists identified specific bacterial sugars that trigger gut neurons to signal the brain, revealing a precise mechanism behind the gut-brain axis.
Untrained CNNs Match Backpropagation at V1: Architecture Over Learning Rules
A study finds that early visual cortex alignment is driven by architecture, not learning rules—untrained CNNs match trained ones at V1.
