The zona incerta is a small region of gray matter that is part of the subthalamus.

Anatomy

This nucleus is located medially to the internal capsule, ventral to the thalamus, and is contiguous with the Thalamic reticular nucleus.

This nucleus separates the lenticular fasciculus from the thalamic fasciculus.

Function

This region receives widespread input from the cerebral cortex and cerebellum, and sends outputs back to the cortex.

Its functions, however, remain largely unknown.

The subthalamus, or prethalamus (formerly described as ventral thalamus), is part of the diencephalon.

During development the subthalamus is continuous with the hypothalamus, but is separated by white matter fibres mainly from the internal capsule.

The internal capsule is an area of white matter in the brain that separates the caudate nucleus and the thalamus from the lenticular nucleus.

It consists of axonal fibres that run between the cerebral cortex and the pyramids of the medulla.

The lenticular fasciculus is a component of the subthalamus. It is sometimes considered synonymous with "field H2 of Forel".

It connects the globus pallidus to the thalamus.

The diencephalon is the region of the brain that includes the thalamus, hypothalamus, epithalamus, prethalamus or subthalamus and pretectum. It is derived from the prosencephalon. The diencephalon is located at the midline of the brain, above the mesencephalon of the brain stem.
