Memory

• Information processing model

  Input (information enters through senses), encoding (information transformed into a format we understand, e.g. sound waves into music), storage (information kept in brain), retrieval (recalling from memory), and output (using information from memory)
• Hippocampus in memory

  Part of the limbic system, memories must pass through hippocampus before entering long-term storage, particularly semantic and autobiographical, after sensory information has been decoded it is combined by the hippocampus into a single experience
• Amnesia

  Anterograde: inability to form new memories, usually caused by damage to the hippocampus, so memories cannot pass from short-term to long-term storage

  Retrograde: inability to recall memories from past, sometimes caused by damage to the frontal lobe, including in Alzheimer's.
• Procedural memory

  Motor skills, how to do things, can be affected by damage to the cerebellum
