===Perirhinal cortex===

Lesions in the perirhinal cortex account for deficits in reference memory and working memory, and increase the rate of [[forgetting]] of information during training trials of the Morris water maze.<ref>{{cite journal | last1 = Liu | first1 = P. | last2 = Bilkey | first2 = D.

Lesions also cause impairment on an object location task and reduce habituation to a novel environment.<ref name=the_effects_of_excitotoxic/>
