Table 1. Summary of behavioral testing.

	Discrimination Index for task greater than zero?
	Control	DES	ISO
Novel Object Recognition	Yes	Yes	Yes
Object-Place Recognition	Yes	Yes	Yes
Object-Context Recognition	Yes	Yes	No
Social Recognition	Yes	Yes	No
Allocentric Object-Place Recognition	Yes	No	No
Object-Place-Context Recognition	Yes	No	No

For each test, recognition of a familiar set of stimuli results in preferential exploration of the novel aspect of the task. Discrimination Index (DI) represents the time spent with the novel object or animal relative to the familiar one, and DI significantly greater than zero demonstrates successful recognition in the task.
