Introduction
The uppermost portion of the diencephalon that includes the trigonum habenulae (habenula), the pineal (gland or body), the posterior commissure, and the medullary layers of thalamus. The epithalamus develops from the diencephalon most dorsal part of prosomere 2.
The adult habenular nuclei acts as a neural relay system, connecting the forebrain with the brain stem. The function appears to be to regulate cognitive behaviors by modulating a range of transmitter system (cholinergic, dopaminergic and serotonergic) activities.
