In this tutorial, we will not specifically focus on the various nuclei and the internal structure of the thalamus, but rather we will be looking at the position of the thalamus into the hemispheres and we will describe some of the structures that are closely related to it.

The location of the thalamus is found at the core of the diencephalon, deep to the cerebral cortices. It works as the central hub, relaying and integrates a myriad of motor and sensory impulses between the higher centres of the brain and the peripheries.

The thalamus is comprised of two symmetrical structures formed from the diencephalon. Each half of the thalamus is elongated along the anteroposterior axis, which gives it an ovoid appearance. It is widest at the posterior section and narrowest at the anterior end. The two thalami are made up of grey matter. This grey matter is partitioned by a “Y” shaped white matter structure, called the internal medullary lamina.

The thalamus is divided into roughly three main parts: the anterior, medial and lateral thalamus.
