| Brain: Habenular nuclei |
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'
|
| Latin |
nucleus habenularis lateralis, nucleus habenularis medialis |
- See habenula for more detailed information.
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:
- lateral habenular nucleus (NeuroNames hier-278, )
- medial habenular nucleus (NeuroNames hier-279, )
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.

Emerging evidence has revealed that there is an enrichment of cells that express the estrogen receptor in the lateral habenula (LHb) region

- Preclinical studies indicate both activation and blockade of serotonin6 (5-HT6) receptors may produce antidepressant-like effects. Depression is a common symptom in Parkinson's disease (PD); however, its pathophysiology is unclear. Here we examined whether 5-HT6 receptors in the dorsal hippocampus (
