A badly burned firefighter has been in an induced coma for 3 weeks. When he awakens, he thanks his son for singing Happy Birthday to him a week earlier

A)
Thalamus
B)
Hypothalamus
C)
Corpus callosum
D)
Basal ganglia
Ans:
A
Feedback:
Coordination and integration of peripheral sensory stimuli occur in the thalamus, along with some crude interpretation of highly emotion-laden auditory experiences that not only occur but also can be remembered. For example, a person can recover from a deep coma in which cerebral cortex activity is minimal and remember some of what was said at the bedside. Inferior to the thalamus, and representing the ventral horn portion of the diencephalon, is the hypothalamus; it is the area of master-level integration of homeostatic control of the body's internal environment. The corpus callosum is a massive commissure, or bridge, of myelinated axons that connects the cerebral cortex of the two sides of the brain. The basal ganglia lie on either side of the internal capsule, just lateral to the thalamus; they supply axial and proximal unlearned and learned postures and movements, which enhance and add gracefulness to UMN-controlled manipulative movements.
