Sham transcranial direct current stimulation (tDCS) decreases FC compared with baseline. a Decreased connectivity between the left VPL (seed in white) and left S1, left parahippocampal gyrus, and amygdala after sham tDCS compared with baseline. Plots show changes in FC from baseline to after the sham treatment period for each patient with fibromyalgia. b Decreased connectivity between the right VPL (seed in white) and left IPL. c Decreased connectivity between the PAG (seed in white) and precuneus. Data shown are Fisher-transformed r values. VPL ventral posterolateral, S1 primary somatosensory cortex, parahipp parahippocampal gyrus, amyg amygdala, IPL inferior parietal lobule, PAG periaqueductal gray, L left, R right, FC functional connectivity
