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.
The reason is that long-term memory is not located in just one specific area of the brain. The hippocampus is the catalyst for long-term memory, but the actual memory traces are encoded at various places in the cortex. The destruction of both hippocampi (as the result of a stroke, for example) has disastrous effects on long-term memory, preventing the individual from learning anything new whatsoever. The most important evidence of the role of the hippocampus in transferring long-term memories has been provided by subjects who had sustained damage to both hippocampi and could not keep things in their memories for more than a few moments.
