The subcallosal area (parolfactory area of Broca) is a small triangular field on the medial surface of the hemisphere in front of the
subcallosal gyrus
The subcallosal gyrus (paraterminal 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. I ...

posterior parolfactory sulcus; it is continuous below with the
olfactory trigone, and above and in front with the
cingulate gyrus
The cingulate cortex is a part of the brain situated in the medial aspect of the cerebral cortex. The cingulate cortex includes the entire cingulate gyrus, which lies immediately above the corpus callosum, and the continuation of this in the c ...

anterior parolfactory sulcus.
The subcallosal area is also known as "Zuckerkandl's gyrus", for
