Lesions of periventricular tissue surrounding the anteroventral third ventricle (AV3V) attenuate salivation and thermal tolerance in response to a heat stress.
The purpose of this study was to determine if ablation of the periventricular tissue that surrounds the anteroventral third ventricle (AV3V) would reduce an animal's ability to withstand a thermal challenge. The results show that AV3V-lesion rats are less capable of withstanding a 37 degrees C heat stress and that this is, at least in part, due to a reduced salivation response.
