Thalami

Thalamus is a part of the brain located in the forebrain directly above the brain stem. It is involved in sensory and motor signal relay and the regulation of consciousness and sleep.

Structure

The thalamus is a large mass of grey matter located in the dorsal part of the diencephalon. It is made up of a number of nuclei, each with distinct connections and functions. The thalamus is divided into two halves, the left and right thalamus, which are connected by the interthalamic adhesion.

Function

The thalamus has multiple functions, primarily to relay motor and sensory signals to the cerebral cortex. It also regulates consciousness, sleep, and alertness.

Clinical significance

Damage to the thalamus can lead to a variety of sensory deficits, including thalamic pain syndrome. Thalamic lesions can also result in thalamic syndrome, which can include sensory loss, spontaneous pain and dysesthesias, and mild hemiparesis.
