Etymology
The term "Medial Dorsal Nucleus" is derived from its anatomical position and structure. "Medial" refers to its location towards the midline of the brain, "Dorsal" indicates its position on the upper side of the brain, and "Nucleus" signifies a cluster of neurons.

Anatomy
The Medial Dorsal Nucleus is located in the anterior part of the thalamus, adjacent to the Third Ventricle. It is divided into three parts: the magnocellular part, the parvocellular part, and the densocellular part. Each part has distinct connections and functions.
Clinical Significance
Alterations in the Medial Dorsal Nucleus have been associated with several neurological and psychiatric disorders, including Schizophrenia, Alzheimer's Disease, and Depression.
