In contrast (pain – visual), positive Z scores indicated pain greater than visual, while negative Z scores indicated visual greater than pain contrasts.
DLPFC, dorsolateral prefrontal cortex; M1, primary motor area; S1, primary somatosensory cortex; PPC, posterior parietal cortex; VPC, ventral premotor cortex; MT, mid temporal cortex; PreCu, precuneus; TH, thalamus.
