There are fifteen health indibiduals recruited in order To explore the changes of functional connectivity in vmPFC with tDCS stimuli after 36 hours sleep deprivation. Colleceting resting-state fMRI data under the tDCS stimuli and sham stimuli conditions. Using the vmPFC as the seed region,and then the time courses of all brain voxels were correlated separately with the mean time course generated from the ROI by Pearson cross-correlation. Finally, we found that tDCS can effectively mediate the dysfunction of brain connectivity.
