Loneliness Linked to Fewer Years Free From Depression and Anxiety
A study of 277,489 adults finds loneliness and social isolation cut years of disease-free life, with men losing nearly 6 mental-health-free years. Healthy habits did not offset loneliness.
Microglia May Hold Alzheimer's Tipping Point, Study Finds
New research on donated human brain tissue identifies a microglial tipping point that may decide whether Alzheimer's pathology leads to dementia.
New HOLMES Model Learns Hierarchical Structure in Real Time
A new computational model called HOLMES uses online inference to learn nested categories from sequential data, supporting one-shot transfer to higher-level concepts without explicit supervision.
Missing Brain Circuit Behind Chronic Fear Identified
Salk researchers discovered the amygdalostriatal transition zone (ASt) sustains long-lasting fear and anxiety behaviors—a missing link between emotion and action.
Long COVID May Damage Dopamine Neurons, Brain Scans Show
A CAMH brain imaging study finds lower dopamine neuron marker levels in people with long COVID, linking the loss to fatigue, low motivation, and memory problems.
Dyscalculia Brain: Neural Circuit Glitches Block Math Strategy Switching
Stanford researchers found that children with developmental dyscalculia show altered cognitive control circuits, making them slower to switch and optimize math strategies.
Sports Boost Motor Skills in Autistic Children, Review Finds
A review of 11 clinical trials finds organized sports — especially martial arts and aquatic training — improve balance and motor skills in children with autism.
Gut Jet Lag: How Time Zone Shifts Disrupt Intestinal Rhythms
A new study from Wroclaw Medical University reveals how long-haul flights desynchronize gut bacteria from the brain's clock, affecting energy and cognition.
How Brain Wave Tuning Maintains Consciousness: New Study
A Kyoto University study shows the awake brain channels information along traveling waves with directional precision, while anesthesia floods it with noisy signal flow.
Traveling Brain Waves: The Visual Cortex's Own Generative Engine
A new Neuron review argues traveling waves in the visual cortex act as a biological generative model, shaping perception, prediction, and memory replay.
Zero-Calibration Brain-Computer Interfaces Edge Closer with 90.97% Accuracy
A new deep learning pipeline combines Riemannian alignment and stochastic weight averaging to enable zero-calibration motor imagery BCIs, achieving 90.97% accuracy in one subject and 74.31% across nine.
Hippocampal Circuit Links Memory Loss to Apathy, Study Finds
A new study links object-location memory errors to clinical apathy in autoimmune limbic encephalitis, tracing both to weakened hippocampus-prefrontal connectivity and hippocampal atrophy.
