A subparietal sulcus (Sulcus subparietalis) or suprasplenial sulcus is a sulcus, or crevice, on the medial surface of each cerebral hemisphere, above the splenium of the corpus callosum, separating the precuneus from the posterior part of the cingulate gyrus. It continuing the original course of the cingulate sulcus posteriorly from where the marginal branch of that fissure bends upward. Anteriorly it originates at the point of the upward bend of the marginal sulcus, where it is frequently confluent with the cingulate sulcus. Posteriorly it extends toward the anterior part of the calcarine sulcus. The connections between the cingulate gyrus and the precuneus are anterior and posterior to the subparietal sulcus.
The precuneus is delineated anteriorly by the marginal branch of the cingulate sulcus, posteriorly by the parietooccipital sulcus, and inferiorly by the subparietal sulcus. The connections between the cingulate and the precuneus gyri are anterior and posterior to the subparietal sulcus.
