Term: Long-Term Potentiation (LTP)
Definition (Myers): an increase in a syapse's firing potential after brief, rapid stimulation. Believed to be a neural basis for learning and memory1
Definition (alternative): a phenomenon was described in the hippocampus that may account for declarative memory2
Contextual explanation: a phenomenon called LTP is related with learning and memory, becoming more efficient at sending signals. Mice that lack an enzyme needed for LTP have trouble getting out of a maze; rats with drugs that enhances LTP get out of a maze much easier.
