Retrograde amnesia: the inability to retrieve memories from prior to development of amnesia

Multiple memory trace theory: episodic memory retrieval creates

memory traces that strenghthen the hippocampal–neocortical ensemble

Encoding: the transformation of memory into a storagable state

Storage: the storing of memory

Retrieval: the accessing of stored memories
