Abstract
The study conducted looks into how animals with excitotoxic lesion to the perirhinal cortex. The extinction paradigm examines how animals that have permanent inactivation of the perirhinal cortex do or do not display fear behavior. Previous extinction paradigms have found that their animals with lesions to the perirhinal have shown deficits to post training lesioning to context fear conditioning. Animals in this paradigm received post training lesions to cued fear conditioning. Based upon early graphing of data it appears that there is an association between fear behavior and perirhinal functioning.
