basal forebrain

A region of the brain consisting of ventral and rostral subcortical regions of the telencephalon, including among others, the basal ganglia, septal nuclei, amygdala, ventral pallidum, substantia innominata, and basal nucleus of Meynert. Every claim on this page comes from the Leumas anatomy graph and carries its source.

What the basal forebrain is

A region of the brain consisting of ventral and rostral subcortical regions of the telencephalon, including among others, the basal ganglia, septal nuclei, amygdala, ventral pallidum, substantia innominata, and basal nucleus of Meynert. The atlas records it as a nerve at the organ scale in the human body.

Where the basal forebrain 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 basal forebrain connects to

The atlas records 9 typed relationships for it, across 3 kinds of connection. part of forebrain.

Supply and innervation

This dataset asserts no arterial supply, venous drainage or innervation for the basal forebrain. 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 basal forebrain area and pars basalis telencephali. Searching any of those names reaches this page.

Questions

Where is the basal forebrain?

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 basal forebrain connect to?

Part of: forebrain.

Is the basal forebrain 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.
