telencephalon

Part of the forebrain consisting of paired olfactory bulbs and cerebral hemispheres. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the telencephalon is

Part of the forebrain consisting of paired olfactory bulbs and cerebral hemispheres. The atlas records it as a nerve at the organ scale in the human body.

Where the telencephalon 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 telencephalon connects to

The atlas records 67 typed relationships for it, across 9 kinds of connection. part of forebrain.

Supply and innervation

Venous drainage: cerebral vein.

Also called

Also recorded as supratentorial region, cerebrum and endbrain. Searching any of those names reaches this page.

Questions

Where is the telencephalon?

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 telencephalon connect to?

Part of: forebrain.

Is the telencephalon 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.
