Overlap of retrieval-related functional connectivity for the whole hippocampus and hippocampal subregions. Clusters indicate regions where functional connectivity changed as function of memory age when the effects of behavior were minimized for all trials. A. Extensive voxel overlap (green) of anterior hippocampus (yellow) and whole hippocampus (blue, previously reported Tallman et al., this issue). B. Same as A, except posterior hippocampus was used as the seed. There was minimal voxel overlap of posterior hippocampus and whole hippocampus connectivity. Posterior hippocampal and whole hippocampal functional connectivity networks had minimal voxel overlap, yet were generally identified the same brain regions (see Table 2 and Table 2 in Tallman et al., this issue). Voxel-wise p < 0.01, cluster-wise p < 0.05. L, Left.
