Abstract
In a preliminary study, it was not found possible to obtain clear-cut data on the interaction between chemical and electrical stimuli, both applied to the same locus in the lateral hypothalamus. In a subsequent study, the sites in the lateral hypothalamus from which water ingestion can be elicited by electrical or chemical stimulation of the brain were found to have little overlap. However, chemical stimulation drinking sites in the zona incerta and lateral hypothalamus were found to all also be sites from which electrical self-stimulation could be elicited. Since nondrinking sites to chemical stimulation could also be found in this area and were also self-stimulation sites, no specific relationship between chemically elicited drinking and electrical self-stimulation can be drawn.
