The thalamus is a large, dual lobed mass of grey matter buried under the cerebral cortex
. It is involved in sensory perception and regulation of motor functions. The thalamus is a limbic system
structure and it connects areas of the cerebral cortex that are involved in sensory perception and movement with other parts of the brain and spinal cord that also have a role in sensation and movement. As a regulator of sensory information, the thalamus also controls sleep and awake states of consciousness.
The thalamus is involved in several functions of the body including:
- Motor Control
- Receives Auditory, Somatosensory and Visual Sensory Signals
- Relays Sensory Signals to the Cerebral Cortex
- Controls Sleep and Awake States
