![Ramón y Cajal draws the hippocampus. For more information about the hippocampus, see this old post! If you like making memories, you like your hippocampus. The hippocampus cycles new information to encode it into memories and then stores it in cortex. Memories that you’ve made recently are still held in the hippocampus, but older memories are stored in cortex- the place where they were first encoded (i.e. auditory memories would go in the temporal lobe, which is where auditory information is processed). This is why HM, who had his hippocampus removed, could still remember everything from before about a year before his hippocampus was surgically removed but could not form new memories afterwards. I’ll talk more about HM another time.
