Recollection in an episodic-like memory task in the rat.

Department of Psychology, University of Durham, Durham, United Kingdom DH1 3LE.

Episodic memory in humans is the conscious recollection of a past event. Animal models of episodic-like memory assess the memory for "what"happened, "where" it happened, and either "when" it happened, or in "which" context it happened, although recollection on such tasks is often difficult to measure. Here we present the first evidence of successful recollection of a past event in a rat in a task which is easily performed, requires little training, and is easily adaptable for other commonly used laboratory species.
