fc analysis – fc during inhibition between right inferior temporal/fusiform gyrus (SR) and TR: FM > HC

TR: L supplementary motor area/superior frontal gyrus	3.76	/	135	−10	16	54

%BR = percentage body regions in pain, fc = functional connectivity, FM = fibromyalgia, HC = healthy controls, SR = seed region, TR = target region, L = left, R = right
