Anteroventral third ventricle lesions abolish lumbar sympathetic responses to insulin.
Insulin has been shown to increase sympathetic nerve activity. Because evidence shows that insulin acts within the central nervous system, we hypothesized that lesions of the anteroventral third ventricle region, an area rich in insulin receptors, would abolish sympathetic responses to hyperinsulinemia. We measured mean arterial pressure and lumbar sympathetic nerve activity in fasted, anesthet...
متن کاملLesions of the anteroventral third ventricle prevent salt-induced hypertension in the borderline hypertensive rat.
Many forms of experimental hypertension depend on the integrity of the periventricular tissue surrounding the anteroventral third ventricle. The current investigation examined the extent to which this forebrain area is necessary for the elaboration of salt-induced hypertension in the borderline hypertensive rat. Eight-week-old male rats were given either electrolytic lesions of the anteroventra...
متن کاملLesions of the anteroventral third ventricle region (AV3V) disrupt cardiovascular responses to an elevation in core temperature.
Blood flow is redistributed from the viscera to the periphery during periods of heat stress to maximize heat loss. The heat-induced redistribution of blood flow is strongly influenced by nonthermal inputs such as hydration status. At present, little is known about where thermal and nonthermal information is integrated to generate an appropriate effector response. Recently, the periventricular t...
متن کاملInvolvement of Median Septum Region in Ghrelin Effects on Morphine-Induced Memory Impairment in Passive Avoidance Learning
Background and purpose: Many studies have reported the effect of morphine on memory impairment. Evidence suggests that ghrelin enhances memory consolidation. The median septum also has a major role in memory and learning mechanisms. The present study aimed at investigating the role of median septum on the effects of ghrelin in morphine-induced amnesia. Materials and methods: In this experiment...
متن کاملLesions of the Anteroventral Third Ventricle and Development of Stress-Induced Hypertension in the Borderline Hypertensive Rat
The anteroventral third ventricle (AV3V) region plays a critical role in the pathogenesis of many forms of experimental hypertension. The present study sought to determine whether the integrity of this area was necessary for the development of stress-induced hypertension in the borderline hypertensive rat (BHR). Male BHRs were assigned to three groups at 8 weeks of age: 1) AV3V lesion, 2) sham ...
