Document Summary
Places, people, actions all in a unique combination. Episodic memories can be captured incidentally, without conscious effort. The hippocampus is thought to be critical for episodic memory, by providing a link to different regions of the neocortex. This idea is called the indexing theory of episodic memory. Storage of the spatial location of objects. Storage of the spatial location of objects is automatically stored by normal rats but not by rats with damage to the hippocampus. Panel a: rats were allowed to explore an arena containing two objects. Panel b: in the test phase the rat was returned to the arena but the location of one of the objects was changed. Control rats explored the moved object much more than they explored the unmoved object. They responded to it as if it were novel. Rats with damage to the hippocampus explored the two objects equally. Thus, automatically capturing information about the location of the objects depended on the hippocampus.
