Thalami

From WikiMD's Wellness Encyclopedia

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[edit | edit source]

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[edit | edit source]

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[edit | edit source]

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.
