Brain: Paraterminal gyrus

Scheme of rhinencephalon. (Gyrus subcallosus labeled at center left.)

Mesal aspect of a brain sectioned in the median sagittal plane. (Rostrum labeled at center left, and paraterminal gyrus is adjacent to rostrum.)
Latin	Gyrus paraterminalis, gyrus subcallosus

The paraterminal gyrus (subcallosal gyrus, peduncle of the corpus callosum) is a narrow lamina on the medial surface of the hemisphere in front of the lamina terminalis, behind the parolfactory area, and below the rostrum of the corpus callosum. It is continuous around the genu of the corpus callosum with the supracallosal gyrus.
