experiments were done in alpha-chloralose-anesthetized , paralyzed , and artificially ventilated cats to determine the effect of afferent renal nerve ( arn ) stimulation on the firing frequency of neurons in the paraventricular nucleus of the hypothalamus ( pvh ) , whose axons project directly to the neurohypophysis ( nh ) , and the contribution of these neurons to the pressor response elicited by arn stimulation .
