subcallosal area in dogs

The subcallosal area (parolfactory area of Broca, area parolfactoria) 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.

What the subcallosal area is

The subcallosal area (parolfactory area of Broca, area parolfactoria) 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. [WP,unvetted]. The atlas records it as a nerve at the organ scale in the dog.

Where the subcallosal area is

It sits within the nervous system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What the subcallosal area connects to

The atlas records 3 typed relationships for it, across 2 kinds of connection. part of forebrain and telencephalon.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the subcallosal area. Only a minority of structures carry those edges here, so an empty answer means nothing has been recorded — not that there is nothing to record.

Also called

Also recorded as adolfactory area, area paraolfactoria, paraolfactory area, parolfactory area, Zuckerkandl's gyrus and area parolfactoria, and 1 more. Searching any of those names reaches this page.

Questions

Where is the subcallosal area?

It sits within the nervous system. Not positioned individually. Drawn inside the structure this dataset says contains it — the containment is asserted, the exact spot within it is not.

What does the subcallosal area connect to?

Part of: forebrain and telencephalon.

Is the subcallosal area the same in other species?

This page describes the dog. The human record of the same structure sits beside it on /compare, over one shared model rather than two atlases built separately.
