Description

The thalamic eminence is part of the diencephalon and lies ventral to the ventral thalamus and dorsal to the preoptic area. This region gives rise to the ventral entopeduncular nucleus that extends into the telencephalon and straddles the diencephalic/telencephalic border. The ventral entopeduncular nucleus is a major afferent nucleus to the habenulae.

Schematic adapted from Mueller 2012 showing the nuclei that comprise the wider thalamus.
