According to a new Journal of Neuroscience report, an underdeveloped brain network underlying inhibition after the age of 30 is associated with increased self reporting of psychological problems such as anxiety and depression.
Researchers have identified functional connectivity problems in brain regions associated with visual processing and attention in Parkinson's patients who experience visual hallucinations.
A new study in Neuron reports a simple, new neuroimaging technique has revealed a correlation between how well a person's brain regions are connected and intelligence.
Researchers say typical neuroimaging studies generally utilize small sample sizes, making them a challenge for other neuroscientists to replicate.
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.
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.
Prolonged anesthesia significantly alters the synaptic architecture of the brain, regardless of age.
Fenofibrate, a drug developed to control cholesterol, alleviated brain and behavioral abnormalities in mouse models of schizophrenia.
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.
