The hippocampus is important in helping the brain to STORE NEW MEMORIES.
Explanation:
People with damage to their hippocampus have virtually no capability of storing verbal or declarative types of memory in long -term memories, that is, they are unable store types of information that are the basis of intelligence. This is often called ANTEROGRADE AMNESIA.
Hippocampi are important in the output pathway from the reward and punishment areas of the limbic system among other structures.
Sensory stimuli or thoughts that cause pain excite the limbic punishment centers while stimuli that cause pleasure, happiness excite to reward centers. Hippocampi especially have a part to play in the response of the brain in making decisions about which of the thoughts are important on the basis of reward or punishment to be good for storing as memories. So any lesion or damage to this area causes loss of memory of the recent happenings both in long and intermediate term.
