  1. SD Somatic depression, NSD Non-somatic depression, HC Healthy control, dAI Dorsal anterior insula, MNI Montreal Neurological Institute, x, y, z are the coordinates of the primary peak locations in the MNI space; F is obtained by one-way analysis of variance; t is obtained by two-sample two-tailed t test (p < 0.05, alphasim correction); L Left, R Right
