paraterminal gyrus

The posterior parolfactory sulcus separates the paraterminal gyrus from BA25.

It interconnects the paraterminal gyrus in the septal area with the hippocampus and lateral olfactory area.

BA25 is located in the cingulate region as a narrow band in the caudal portion of the subcallosal area adjacent to the paraterminal gyrus.

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.
