Dr.Allenby has implanted electrodes in the brain of a cat.By passing differing electrical frequencies through the wires Dr.Allenby finds that he can cause the cat to fall into a deep sleep, or awaken suddenly.Based on this information, it is most likely that the electrodes have been implanted in the cat's:

B)hypothalamus
C)thalamus

Question

Quizplus · Accepted Answer

The reticular formation of the brainstem is responsible for regulating sleep and wakefulness. By passing electrical frequencies through implanted electrodes in this region, Dr. Allenby is able to manipulate the cat's sleep cycles. The cerebellum is involved in motor coordination, the hypothalamus is involved in regulating basic bodily functions such as hunger and thirst, and the thalamus is involved in relaying sensory information to other parts of the brain. While these regions may also play a role in sleep regulation, the reticular formation is the most directly involved.
