Fig. 5From: Changes in resting state functional connectivity after repetitive transcranial direct current stimulation applied to motor cortex in fibromyalgia patientsCorrelation between change in FC and change in clinical pain after real transcranial direct current stimulation (tDCS). Patients with reduced FC between the L VPL thalamus (seed in white) and left S1/M1 and right posterior insula had greater reductions in clinical pain after real tDCS compared with sham (displayed at p = 0.005). Data shown are Fisher-transformed r values.
