Subparietal Sulcus

The Sub-Parietal Sulcus (subPS) can be considered the parietal continuation of the CingS and separates the mesial parietal lobe (precuneus) from the posterior sector of cingulate gyrus. It has an anterior-posterior course starting immediately behind the beginning of the ascCinS (1), and continues posteriorly and inferiorly hugging the splenium of the corpus callosum (2). It has side branches that, most often, give the overall impression of an H; it can also be constituted by several independent segments. Because of the variability of presentation it is important to devise a consistent approach to the tracing.
