A brain network consisting of the thalamus, anterior and posterior cingulate cortex, and angular gyri was implicated in the loss, and return, of consciousness under both anesthetic and natural sleep.
A new computational model predicts how information deep inside the brain could flow from one network to another, and how neural network clusters can self optimize over time.
Cortical thickness and regional brain connectivity pay an equally important role in linking brain and behavior.
APOEe4, a gene associated with Alzheimer's disease risk, doesn't appear to directly affect memory performance or brain activity in older adults without cognitive impairment. However, the gene does seem to influence brain regions and systems that older at-risk adults activate to support successful memory recall.
The activity of a network of dopamine neurons reflects both the innate preferences for smell and taste, as well as the physiological state of fruit flies.
Examining the brains of frequent cannabis users, researchers have identified a pattern of connectivity related to craving the substance. The findings add weight to the idea that brain regions do not work in isolation, but via the connectivity of multiple networks that signal to each other depending on state and need. Brain connectivity during cannabis cravings is not static but has fluctuations in connection patterns between the central executive network and nucleus accumbens.
