Subcallosal area

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, from which it is separated by the posterior parolfactory sulcus; it is continuous below with the olfactory trigone, and above and in front with the cingulate gyrus; it is limited anteriorly by the anterior parolfactory sulcus.

Anatomical terms of neuroanatomy

The subcallosal area is also known as "Zuckerkandl's gyrus", for Emil Zuckerkandl.[1]

The parahippocampal gyrus, subcallosal area, and cingulate gyrus have been described together as the periarcheocortex.[2]

The "subcallosal area" and "parolfactory area" are considered equivalent in BrainInfo,[3] but in Terminologia Anatomica they are considered distinct structures.
