Mesal aspect of a brain sectioned in the median sagittal plane. The habenular nuclei
are not labeled directly, but after expanding, look to region with 'habenular commissure', 'pineal body', and 'posterior commissure'
The habenular nuclei comprise a small group of nuclei that are part of the epithalamus of the diencephalon, situated at the posterior end of the thalamus, on its upper surface.
The habenular nuclei are typically divided into:
The pineal gland is attached to the brain in this region.
Nerve impulses from the habenular nuclei are transmitted to the septal nuclei via the stria medullaris, which is found on the medial surface of the thalamus.
