Hacker News with Generative AI: Neuroscience

Moments of Awakening (astralcodexten.com)
Consciousness is the great mystery. In search of answers, scientists have plumbed every edge case they can think of - sleep, comas, lucid dreams, LSD trips, meditative ecstasies, seizures, neurosurgeries, that one pastor in 18th century England who claimed a carriage accident turned him into a p-zombie. Still, new stuff occasionally turns up.

What Your Brain Looks Like When You Solve a Problem (gizmodo.com)
Researchers have revealed that epiphanies physically reshape brain activity. What’s more, they discovered that people remember epiphanies better than solutions reached through a more methodical approach. These results could have important implications for how instructors approach teaching in classrooms.

Cognitive Benefits of Open-Skill Sports in Childhood: Evidence from ABCD Study (nlm.nih.gov)
This study analyzed baseline data from the Adolescent Brain Cognitive Development (ABCD) study, comprising 11,869 children aged 9-10 years. Participants were categorized into open-skill sports group (OSG), closed-skill sports group (CSG), and non-sport group (NSG). Cognitive performance was assessed using seven tasks from the NIH Toolbox, covering executive function, processing speed, and language domains. Group differences were examined using ANCOVA, controlling for sex, race, parental education, income, Area Deprivation Index (ADI), body mass index (BMI), and total time spent in activities.

Methylene Blue Address Vascular-Hypometabolism in Alzheimer's Disease (gethealthspan.com)
Alzheimer’s disease (AD) is often associated with amyloid plaques and neurofibrillary tangles, yet growing evidence supports a vascular-hypometabolism hypothesis in which cerebral hypoperfusion and mitochondrial dysfunction—particularly at the level of cytochrome c oxidase—drive early disease processes.
