Abstract: The effects of amygdalae(AE)lession in rats were tested for the aquisition and retention of spatial cognitive tasks in the Morris maze.The results indicated that subjects with AE Lesion produced spatial cognitive deficits and they usually used taxic strategies which were different from the mapping strategies used by the control subjects.The different strategies suggest that AE is related to the spatial cognitive system and belong to the auxiliary structure of the systme.
