Hippocampal connectivity during recollection. Thresholded SPM{t} map (p(FWE) < 0.05) for the PPI of right hippocampus × REC > FAM together with the hippocampal seed region overlaid on the mean T1 image. A recollection-specific increase in hippocampal contribution is located between the posterior end of the cingulate cortex, the splenium, and the fornix, possibly including the retrosplenial cortex. The cluster is adjacent to (and slightly overlapping with) the PCC/precuneus cluster found in the contrast REC > NEW (Fig. 2, Table 3). This effect is consistent with the suggestion that the retrosplenial cortex relays information from the hippocampus to the cortex, driving reinstatement of encoding related representations (Johnson and Rugg, 2007).
