Brain areas associated with working memory also gauge the quality and uncertainty of memories. Researchers reveal details about the neural mechanisms of working memory that allow us to make decisions based on our certainty of memories.
Reinterpreting stress response as performance-enhancing makes people less anxious and improves general wellbeing, researchers report.
Stem cell study reveals astrocytes carrying the Alzheimer's associated APOE4 gene release more cholesterol than those carrying the APOE3 gene. Findings shed light on how different versions of the APOE gene in astrocytes influence amyloid-beta production and how the oversupply of cholesterol associated with APOE4 astrocytes may promote amyloid-beta formation in Alzheimer's patients.
Heart rate synchronization occurs, even when people listen to a story alone, when paying attention to certain points of a story.
Cholesterol produced by astrocytes in the brain is required for the production of amyloid-beta. The findings shed light on how and why amyloid-beta forms, and may explain why genes associated with cholesterol have been implicated as risk factors for Alzheimer's disease.
Altered behaviors associated with LSD may be caused by a reduction in the normal communication between the hippocampus and visual cortex.
Amyloid-beta proteins created in the liver are carried in the blood by lipoproteins to the brain. This results in neurodegeneration, brain atrophy, and inflammation, which are common features of Alzheimer's disease.
A new bio-inspired slow-release system for site 1 sodium channel blockers helps release anesthesia, providing prolonged nerve blocking with minimal toxicity.
Drugs that stabilize amyloid fibril "frustration" block further aggregation and could provide a new method to prevent the progression of Alzheimer's.
Researchers shed light on how the brain responds to unexpected sounds.
