Study reveals how interaction between neural networks changes during working memory

How does the cross-talk between brain networks change when working memory - the mental assembly of information needed to carry out a particular task—is engaged? Investigators at Massachusetts General Hospital (MGH) have found that dopamine signaling within the cerebral cortex can predict changes in the extent of communication between key brain networks during working memory. Their findings receiving online publication in Science Advances may lay the groundwork for studies of how disruptions in dopamine signaling contribute to working memory deficits that are characteristic of schizophrenia and other psychiatric disorders.
