The picture of the brain seems to have dots in the orbitofrontal cortex, genu of the corpus callosum and the medial surface of the postcentral gyrus, plus a flower in the cerebellum.

-
The oblique part is named the postcentral sulcus, and commences below, about midway between the lower end of the central sulcus and the upturned end of the lateral fissure.
-
Anteriorly, it overlaps the lobulus centralis, from which it is separated by the postcentral fissure; laterally, it is continuous with the quadrangular lobule in the hemispheres.
-
The posterior central gyrus (gyrus centralis posterior; ascending parietal convolution; postcentral gyre) extends from the longitudinal fissure above to the posterior ramus of the lateral fissure below.
-
The inferior parietal lobule (lobulus parietalis inferior; subparietal district or lobule) lies below the horizontal portion of the intraparietal sulcus, and behind the lower part of the postcentral sulcus.
-
The horizontal limb of the intraparietal sulcus begins from the junction of the lower with the middle third of the postcentral sulcus and curves backward parallel to the longitudinal fissure, midway between it and the parietal eminence; it then curves downward to end midway between the lambda and the parietal eminence.
-
From about the middle of the postcentral sulcus, or from the upper end of its inferior ramus, the horizontal portion of the intraparietal sulcus is carried backward and slightly upward on the parietal lobe, and is prolonged, under the name of the occipital ramus, on to the occipital lobe, where it divides into two parts, which form nearly a right angle with the main stem and constitute the transverse occipital sulcus.
-
The precetral and postcentral sulci are practically parallel to the central sulcus; they are situated respectively about 15 mm. in front of, and behind, it.
-
One, the supramarginal, arches over the upturned end of the lateral fissure; it is continuous in front with the postcentral gyrus, and behind with the superior temporal gyrus.
