Rats with bilateral electrolytic or ibotenic acid lesions that were centred in perirhinal cortex displayed a significant delay-dependent deficit on a delayed nonmatch to position task in the T maze. Although the removal of prominent extramaze visual cues did not affect the performance of these rats, rotating the maze between the sample and test phases did, indicating that rats were using a spatial strategy. Interestingly, a further group of rats with hippocampal and perirhinal damage displayed… CONTINUE READING
