Relationship of the mechanical punctate pain threshold with the (a) absolute power and (b) relative power at the delta to gamma bands in the pain-related regions in healthy individuals. The P-value of the correlation analysis is color-coded, with a significant value denoted with yellow. *P < .05 with false discovery rate correction. MPPT, mechanical punctate pain threshold; ACC, anterior cingulate cortex; LOF, lateral orbitofrontal cortex; MOF, medial orbitofrontal cortex; SI, primary somatosensory cortex; PCC, posterior cingulate cortex; MI, primary motor cortex; V1, left supraorbital (the first branch of the trigeminal nerve dermatome); T1, proximal medio-ventral forearm (the first thoracic nerve dermatome)
