piriform cortex in dogs

The subdivision of the laminated olfactory cortex with only three main layers that receive monosynaptic input from the olfactory bulb via the lateral olfactory tract; it is located bilaterally in the ventrolateral forebrain and is commonly divided into anterior and posterior regions. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the piriform cortex is

The subdivision of the laminated olfactory cortex with only three main layers that receive monosynaptic input from the olfactory bulb via the lateral olfactory tract; it is located bilaterally in the ventrolateral forebrain and is commonly divided into anterior and posterior regions. The atlas records it as a nerve at the organ scale in the dog.

Where the piriform 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 piriform cortex connects to

The atlas records 7 typed relationships for it, across 4 kinds of connection. part of anatomical entity, brain and nervous system, and 1 more.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the piriform 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 cortex piriformis, primary olfactory areas, area prepiriformis, eupalaeocortex, olfactory pallium and palaeocortex II, and 7 more. Searching any of those names reaches this page.

Questions

Where is the piriform 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 piriform cortex connect to?

Part of: anatomical entity, brain, nervous system and olfactory cortex.

Is the piriform cortex 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.
