Medial Habenula Neurons is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The medial habenula (MHb) is a small bilateral nucleus located in the epithalamus, forming part of the habenular complex. It receives input primarily from the septal nuclei and projects to the interpeduncular nucleus (IPN), creating a crucial pathway for limbic system communication. [1]

Medial habenula neurons exhibit distinct morphological features:
The medial habenula serves as a critical relay between the septal nuclei and the interpeduncular nucleus:
Septal Nuclei → (cholinergic/GABAergic) → Medial Habenula → (glutamatergic/substance P) → Interpeduncular Nucleus
