What does semantic dementia reveal about the functional role of the perirhinal cortex?
Simons, J.S., Graham, K.S., & Hodges, J.R. (1999). Trends in Cognitive Sciences, 3, 248-249.
Volumetric analysis of MRI scans suggests the perirhinal cortex may be preserved in semantic dementia. Recent findings of preserved non-verbal new episodic learning in the disorder imply that the perirhinal cortex may be implicated in recognition memory, and not the processing of semantic knowledge as has been claimed.
