Top, The proposed functional subdivisions of PCC. The dorsal PCC is shown in warm colors and the ventral PCC in cold colors. The ventral branch of the subparietal sulcus anatomically separates the two functional regions (Vogt et al., 2006). Brodmann cytoarchitectonic regions 23 and 31 are labeled. Bottom, A schematic of the functional connectivity from the PCC subdivisions. The ventral and dorsal PCC are strongly interconnected and project to other regions of the DMN, including the ventromedial prefrontal cortex (vmPFC), and inferior parietal lobe (data not shown). The dorsal PCC shows stronger functional connectivity to “task-positive” regions within the cognitive control network, and we propose that the ventral PCC is more strongly functionally connected to medial temporal lobe (mTL) structures including the hippocampus.
