Fig. 5.

Functional connectivity networks changed significantly before and after ECT and the brain regions corresponding to those FCs in response to ECT therapy. Circle plots: the 246 FC nodes were grouped into 24 macroscale brain regions that were anatomically defined by the Brainnetome Atlas. Each line indicated that functional connectivity changed significantly before and after ECT (paired t-test, p < 0.01, FDR corrected). Matrix plots: rows and columns represented predefined macroscale regions in Brainnetome Atlas, and a bigger and darker circle represented a bigger number of FCs. Names of 24 macroscale regions were colored according to their lobe locations.
