Feedback:
The hippocampus functions in learning and long-term memory. The limbic system is located between the cerebrum and the inner brain. (The term "limbic" literally means "pertaining to a margin or edge.") It is largely responsible for maintaining a person's level of awareness. The limbic system includes the hippocampus and the reticular formation. The reticular formation plays a role in allowing sensory input to enter the cerebral cortex. It also governs wakefulness and sleep, through a portion of the reticular formation called the reticular activating system (RAS).
