A closer look at Parkinson’s brains finds tau where standard tests saw little
By examining six brain regions at single-molecule resolution, researchers identified a layer of tau pathology that conventional tissue…
Simple Blood Test May Predict Alzheimer’s Years Before Brain Scans Show Signs
A long-term study suggests that a specific blood biomarker may reveal the earliest biological shifts linked to Alzheimer’s…
Threat-response in the brain’s amygdala linked to sex-specific patterns of alcohol use
New research shows that the threat-response in the brain’s amygdala (which processes emotions) is linked to different patterns…
Brain pathway explains how stress drives alcohol-seeking behavior
Why do stressful moments so often push people toward habits like drinking? A new study from Texas A&M…
Machine learning detects early brain changes linked to Alzheimer’s disease
Worcester Polytechnic Institute (WPI) researchers have used a form of artificial intelligence (AI) to analyze anatomical changes in the…
Study reframes amygdala as the sophisticated learning arbiter
A Dartmouth study challenges the conventional view that the amygdala-the two-sided structure deep in the brain involved in…
Low-fiber diets quickly impair emotional memory in aging brains
Past studies in animals have shown that a highly processed diet is linked to memory problems and inflammation…

Suppressing brain immune cells enhances memory recall in young mice
Babies of every species from mouse to human rapidly forget things that happen to them-an effect called infantile…
Blocking microglia can prevent infantile amnesia
Scientists have found that blocking microglia (specialist immune cells in the brain) prevents infant forgetting (“infantile amnesia”) and…
