FIGURE 1.

(a) Significant regions in the group comparison between OCD patients and HCs. Warm/cool colors indicate regions showing higher/lower dALFF values in the OCD group than in HCs. (b) Negative correlation between illness duration and dALFF values in the right IPL. (c) Negative correlation between HAMD and dALFF values in the left cerebellum. dACC, dorsal anterior cingulate cortex; dALFF, dynamic amplitude of low‐frequency fluctuation; dlPFC, dorsolateral prefrontal cortex; HAMD, Hamilton Depression Rating Scale; HCs, healthy control subjects; IPL, inferior parietal lobule; ITG, inferior temporal gyrus; MOG, middle occipital gyrus; mPFC, medial prefrontal cortex; MTG, middle temporal gyrus; OCD, obsessive–compulsive disorder; PCC, posterior cingulate cortex
