Mr. Hui had a stroke in the thalamus. Will he experience problems with sensation, motor control, or both? Explain
What will be an ideal response?
Mr. Hui will experience difficulty with both sensation and motor control. The thalamus relays most incoming sensory information to the appropriate region of the cerebral cortex for processing and perception. As with the somatic senses of touch and pain, the cerebral cortex interprets the majority of special sensory information and the thalamus is the "gateway" for the entry of most special sensory stimuli into the cerebral cortex (olfaction is an exception). The thalamus plays a role in motor control as well. It stimulates upper motor neurons to initiate movement during voluntary motor control.
