Neuroimaging maps interaction between neural networks during working memory.


Performance of cognitive tasks requires reallocation of resources within and among cortical networks. Understanding the molecular mechanisms that govern such network dynamics is a longstanding goal of cognitive neuroscience. A well-studied example is the modulatory role of prefrontal dopamine signalling in working memory, a key component of executive function. However, it is still unclear how the cross-talk between brain networks
