In the temporal organization of episodic memory, the hippocampus supports the experience of elapsed time.

Space and time are both essential features of episodic memory, for which the hippocampus is critical (Howard & Eichenbaum, 2015). Spatial tasks have been used effectively to study the behavioral relevance of place cells. However, the behavioral paradigms utilized for the study of time cells have not used time duration as a variable that animals need to be aware of to solve the task.

Displaced Object Recognition Memory in Rats.

The Displaced Object Recognition (DOR) task, sometimes called the Novel Object Location task, assesses spatial recognition memory without navigational demands, explicit instruction, or the need for multiple days of training. This memory task has two phases. First, the subject is familiarized to an open arena with two objects and is allowed to explore the objects.
