  5. Cerebral cortex
Correct answer

Reticular formation

Explanation

During an animal experiment, surgical damage of certain brain structures has caused deep prolonged sleep. What structure is most likely to cause such condition, if damaged?"Basal ganglion" -> controls voluntary motor nucleus as eye movement. "Red nuclei" -> controls muscle of shoulder (such as swinging arms). "Hippocampus" -> controls the formation of memories. "Cerebral cortex" -> controls all 4 lobes and their function. "Reticular formation" -> controls sleep and alertness so injury to it will prolong sleep and possibly coma.
