A.
The thalamus processes & transmits movement & sensory information, and it is essentially a relay station, taking in sensory information & then passing it on to the cerebral cortex.
B.
It regulates the body's voluntary motor control, consciousness & its sleep/wake cycle. It also regulates the senses of sight, sound, taste, touch & the sense of where the person's body is in space.
C.
Damage to this system can put a person at risk for irreversible coma. An inherited condition causes the thalamus to degrade over time, leading to insomnia that can prove fatal.
D.
The thalamus may also be involved in the regulation of some types of memory.
