Resting state functional network from dorsal caudate and impaired cognitive flexibility in OCD patients and HC.
(A) Group difference in resting state functional network from the left dorsal caudate (L-DC) associated with impaired cognitive flexibility (cluster size corrected significance p < .05 FDR corrected, after applying a per-voxel height threshold of p < .001). L-DC, left dorsal caudate; dACC, dorsal anterior cingulate cortex; AI, anterior insula.
(B) Functional connectivity from DC and scores of cognitive flexibility (%PE) in the OCD and HC groups. r = Spearman's rank-order correlation coefficient.
