Both activated and less-activated regions identified by functional MRI reconfigure to support task executions

Introduction Functional magnetic resonance imaging ( fMRI ) has become very important for noninvasively characterizing BOLD signal fluctuations, which reflect the changes in neuronal firings in the brain. Unlike the activation detection strategy utilized with fMRI , which only emphasizes the synchronicity between the functional nodes (activated regions) and the task design, brain connectivity and network theory are able to decipher the...
