Question

a patient is unresponsive to sensory stimuli and a brain scan of the cerebrum shows no cortical activity. during surgery to relieve pressure on her brain, the neurologist notices damage to part of her diencephalon, explaining her symptoms. what part is damaged?

Answer 1

In a patient that is unresponsive to sensory stimuli and a brain scan of the cerebrum shows no cortical activity the THALAMUS is damaged. The thalamus is a structure of the diencephalon.

The thalamus is a brain structure of the diencephalon (also known as the interbrain) found above the midbrain, near the center of the brain.

The thalamus plays diverse roles which include sensory relay in visual and gustatory systems, motor skills, emotions, memory skills, sensorimotor-associated functions, etc.

The thalamus is also involved in the control of sleep, consciousness, and/or alertness.
