ABSTRACT
Electrical self-stimulation in the lateral hypothalamus of both hemispheres was recorded in 14 rats before and after administration of a unilateral ibotenic acid lesion of the cell bodies in the region of the lateral preoptic area. A significant decrease in the rate of self-stimulation at each of two stimulation intensities was found when the electrode was placed in the hemisphere in which the ibotenic acid lesion was made. This decrease remained constant over 21 days of testing. No changes were detected in rate of self-stimulation in the intact contralateral hemisphere. These results provide evidence for a role in lateral hypothalamic self-stimulation of intrinsic neurons located in the region of the lateral preoptic area.
