Learning & Memory Poster
Recognition memory enables us to make judgements about whether or not we have encountered a particular stimulus before. This poster outlines the cellular mechanisms underlying recognition memory and its links to long-term depression, as well as the use of pharmacological intervention to assess the role of neurotransmitters in recognition memory.
