(A) Horizontal, sagittal, and coronal slices showing that the functional connectivity pattern of the inferior ventral caudate included the bilateral hippocampus (P < 0.05, familywise error-corrected). (B) The degree of functional connectivity between the VCi and MTL was positively associated with caudate D2DR BPND. (C) Path analysis showing that the link between caudate D2DR BPND and episodic memory was mediated through functional connectivity between the VCi and MTL. c, coefficient. Both the total and indirect effects were significant (P < 0.05), whereas the direct effect (dashed line) was not.
