Alzheimer's brain stimulation: best sites are not the most affected
New research shows that optimal brain stimulation sites for Alzheimer's are not where connectivity is most altered, but where the network is most responsive.
AI Learns to Decode Perceptions from Resting Brain Activity
Researchers trained a masked autoencoder on hours of spontaneous neural activity from a blind participant, achieving 84% accuracy in decoding perceptions.
Eye State Reverses Alpha Brain Wave Link to Mind Wandering
A new study shows that whether your eyes are open or closed flips the relationship between alpha brain waves and mind wandering, resolving long-standing contradictions in neuroscience.
Two Brain Circuits Control Which Behaviors Become Habits and How Strongly
A new Kyoto University study identifies two distinct neural circuits that govern habit formation and execution intensity, explaining why habits vary between individuals.
8-Hour Eating Window May Boost Aging Brain Health
A small trial found that older women who ate within an 8–9 hour daily window improved planning and problem-solving skills more than those eating over 12 hours, even with similar weight loss.
Vagus Nerve Gut Signals Drive Spatial Memory Formation
New research shows the vagus nerve transmits gut nutrient signals to the hippocampus, boosting acetylcholine and spatial memory. Chronic junk food impairs this pathway.
AI Voice Clones 20% Easier to Understand in Noise Than Human Speech
A new study shows AI voice clones are up to 20% more intelligible than human voices in noisy environments, with implications for hearing aids and brain training.
Digital cognitive training improves quality of life for adults with ADHD
New research shows that digital cognitive training can enhance quality of life and reduce inattention in adults with ADHD, offering a non-drug option for symptom management.
