perirhinal cortex

Region of cortex near to the rhinal sulcus. It is defined differently in different nomenclatures, due in part to the lack of agreement on the definition of the border of this region. In the rat, the perirhinal cortex occupies only caudal levels of the rhinal sulcus while in the monkey, it occurpies the full rostrocaudal extent of the rhinal sulcus (Burwell et al., Hippocampus, 5: 390-408, 1995). Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the perirhinal cortex is

Region of cortex near to the rhinal sulcus. It is defined differently in different nomenclatures, due in part to the lack of agreement on the definition of the border of this region. In the rat, the perirhinal cortex occupies only caudal levels of the rhinal sulcus while in the monkey, it occurpies the full rostrocaudal extent of the rhinal sulcus (Burwell et al., Hippocampus, 5: 390-408, 1995). The atlas records it as a nerve at the organ scale in the human body.

Where the perirhinal cortex 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 perirhinal cortex connects to

The atlas records 5 typed relationships for it, across 3 kinds of connection. part of cerebral cortex and telencephalon.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the perirhinal cortex. 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 perirhinal area, perirhinal cortex, Brodmann's area 35, area perirhinalis and perihinal area. Searching any of those names reaches this page.

Questions

Where is the perirhinal cortex?

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 perirhinal cortex connect to?

Part of: cerebral cortex and telencephalon.

Is the perirhinal cortex the same in other species?

Leumas holds the same relationship vocabulary for every species it carries, so where another dataset records this structure you can put the two side by side on /compare.
