The accumulation of amyloid-beta and tau proteins disrupts the connections between brain regions associated with memory years before symptoms of Alzheimer's disease appear.
Researchers have identified a link between real-time creativity, semantic memory structure, and functional connectivity in the brain.
People who experienced sexual abuse or suffer from PTSD have reduced connectivity in the ventral and dorsal attention network (VAN-DAN network) compared to those with no history of abuse or PTSD.
Functional connectivity was reduced within and between several brain networks in children raised in disadvantaged neighborhoods. Researchers say a positive home and school environment can mitigate some of the effects.
Fenofibrate, a drug developed to control cholesterol, alleviated brain and behavioral abnormalities in mouse models of schizophrenia.
Prolonged anesthesia significantly alters the synaptic architecture of the brain, regardless of age.
Both the default mode network and salience network in superagers had stronger connectivity than typical older adults and similar connectivity as younger adults. Superagers performed similarly to young adults and better than typical older adults in recognition and episodic memory tasks.
Investigating 32 key nutrients in the Mediterranean diet, researcher report aging individuals with more abundant key nutrients in their blood had better functional connectivity and improved cognitive performance than those lacking the nutrients.
