Effects of tDCS of the DLPFC on brain networks: A hybrid brain modeling study
Fig 6
Impact of structural connectivity on dynamic functional connectivity associated with the stimulated regions in left DLPFC-tDCS protocol (F3a-Fp2c).
(A) Impact of SC on dFC of anodically stimulated region (L.rMFG). (B) Impact of SC on dFC of cathodically stimulated region (L.LOF). The horizontal coordinates represent the changes in FC between whole-brain and stimulated brain regions within each sliding window of left DLPFC-tDCS compared to Without-stimulation. The vertical coordinates represent brain regions after sorting from weak to strong (bottom to top) SC strength between whole-brain and anodically or cathodically stimulated regions. Only the FC in the left DLPFC-tDCS that is significantly different from Without-tDCS (paired sample t-test) is colored, while the remaining nodes are white. Warmer colors correspond to an increase in FC, while cooler colors correspond to a decrease in FC. The color bars indicate statistical t-values ().
