Abstract
WE examined the role of the parahippocampal regions in humans during t wo types of verbal recognition process, i.e. delayed matching and non- matching, by measuring regional cerebral blood flow (rCBF) using PET. The results showed differential activation of each parahippocampal reg ion during verbal memory tasks in which the side activated shifted dep ending on the nature of the task employed; an increase in rCBF in the left parahippocampal gyrus was associated with retrieval strategy of n on-matching, and an increase in rCBF in the right parahippocampal gyru s was associated with retrieval strategy of matching. We conclude that lateralized parahippocampal activation may depend on the type of resp onse required.
