The amygdala and hippocampus are part of the limbic system and play a major role in our memory. The amygdala determines what memories are stored and where they are stored while the hippocampus is responsible for sending out memories to the appropriate areas of our brain for long term storage. The hippocampus retrieves the appropriate memories when it is necessary.
Certain areas of the brain are especially important in the formation and retention of memory: The hippocampus (so- called because it's shape resembles a seahorse) is a structure in the brain that has the main role in processing information as long-term memory. The amygdala, an area near the hippocampus, processes emotion and helps to imprint emotive memories in the brain.
