Definition

The subcallosal area refers is a cortical region on the inner surface of each cerebral hemisphere. It is situated below the rostrum of the corpus callosum and in front of the paraterminal gyrus. Although there are slight variations in its definition, some important gyri in the limbic lobe exist within the subcallosal area. These gyri include the subcallosal gyrus (which continues from the cingulate gyrus beneath the rostrum of the corpus callsoum), and the paraolfactory gyri (which are in front of the paraterminal gyrus). Some sources also consider the paraterminal gyrus as part of the subcallosal area, which is located in front of the lamina terminalis.
