diencephalon
The division of the forebrain that develops from the foremost primary cerebral vesicle. Every claim on this page comes from the Leumas anatomy graph and carries its source.
What the diencephalon is
The division of the forebrain that develops from the foremost primary cerebral vesicle. The atlas records it as a nerve at the organ scale in the human body.
Where the diencephalon 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 diencephalon connects to
The atlas records 45 typed relationships for it, across 9 kinds of connection. part of forebrain.
Supply and innervation
This dataset asserts no arterial supply, venous drainage or innervation for the diencephalon. 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 DiE, between brain, interbrain, mature diencephalon, thalamencephalon and betweenbrain, and 1 more. Searching any of those names reaches this page.

Questions
Where is the diencephalon?
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 diencephalon connect to?
Part of: forebrain.
Is the diencephalon 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.
