Studies of the default mode network based on resting-state fMRI

Most of the functional magnetic resonance imaging studies show that there are functional activities in the absence of any experimental tasks.These findings suggest the presence of default network during resting-state.Many experiments have also proved this default mode network(DMN)hypothesis is true.Certain brain regions,including posterior cingulate cortex,precuneus,medial and prefrontal cortex constitute the DMN.This article reviewed the advance in this field.
