Long-Term Potentiation (LTP): This is a long-lasting strengthening of synapses between nerve cells. It's considered one of the major cellular mechanisms that underlies learning and memory.
Reconsolidation: The process by which existing memories are recalled and then stored again for later retrieval.
Sleep Spindles: Bursts of brain activity visible on an EEG that occur during stage 2 sleep. They are thought to play a role in consolidation of declarative memories.
