NFL Players Show Fourfold Increase in Neurodegenerative Death Risk
A new study of 19,824 NFL players finds they are four times more likely to die from neurodegenerative diseases like dementia and Parkinson's, with younger players facing even higher risks.
1,000-Subject Study Maps Brain Aging Using Wearable Tech
A partnership between UCSF Neuroscape and Samsung is tracking 1,000 adults aged 40-89 with Galaxy Watches and tablets to predict cognitive decline from real-world biometric data.
Infrasound Rewires Ear Mechanics: New Pathway to Brain
Infrasound below 16 Hz bypasses standard hearing cells, vibrating support cells that generate electric fields to trigger unique nerve pathways.
Single Human Neuron Has Processing Power of Entire Neural Network
A new study shows that one human cortical neuron can perform computations equivalent to a deep artificial neural network, challenging the idea that brain size alone explains intelligence.
AI Models Show Brain-Like Reward Circuits: Lessons for Human Motivation
Researchers found that Vision-Language models have reward-anticipating units similar to the human nucleus accumbens. Perturbing these units causes anhedonia-like behavior, advancing our understanding of motivation.
17 New Brain Regions Found to Process Language
MIT researchers analyzed fMRI data from over 700 people and discovered 17 hidden brain regions that process language, including areas in the cerebellum and deep subcortical structures.
One Cocaine Dose Leaves a Genetic Scar That Lasts Weeks
A single cocaine exposure permanently rewires the genome inside reward neurons, creating a physical 'scar' that persists for at least two weeks and primes the brain for addiction.
Mild Sleep Loss Drives Weight Gain and Inactivity — Even 80 Minutes Matters
Shortening nightly sleep by 80 minutes for six weeks led to 1 lb weight gain and 17 more minutes of daily sedentary time, with stronger effects in men and postmenopausal women.
Astrocytes Act as Gatekeepers of Long-Term Memory Persistence
Astrocytes actively control memory stability by physically wrapping around engram neurons via a protein called Ank2. Disrupting this mechanism erases memories within weeks.
Causal Network Mapping Isolates Core Brain Circuits of OCD
Researchers identified four core brain hubs driving OCD using Causal Network Mapping on lesional cases, offering a precise target for personalized rTMS therapy.
Alzheimer’s Study: Amyloid Beta and Hypoperfusion Are Mutually Reinforcing
A whole-brain model shows that amyloid beta accumulation and reduced blood flow reinforce each other, and localized hypoperfusion can trigger brain-wide disease.
AI Uncovers Hidden Gray Matter Lesions in Multiple Sclerosis
A new AI framework reveals thousands of previously invisible gray matter lesions in MS patients using legacy MRI scans, offering a clearer picture of disease progression.
