Relationship between arterial baroreflex, cardiopulmonary vagal reflex and renal natriuretic response to saline in conscious rabbits.
1. We have previously shown that normotensive rabbits with a genetic impairment in arterial baroreflex sensitivity showed a delayed sodium excretion and failed to increase their renal blood flow in response to a saline infusion that did not alter blood pressure. These renal haemodynamic and excretory abnormalities were abolished by renal denervation. The present study determined the sensitivity...
متن کاملResponse of respiratory motoneurons to release from vagal inhibition in the rabbit.
Long-lasting effects of vagal input on phrenic (Phr) and external intercostal (EI) motoneuronal output were studied on 16 anesthetized rabbits breathing spontaneously or paralysed and ventilated by a phrenic nerve-driven pump. Withholding of ventilation by tracheal occlusion or by switching off the servorespirator maintained for seven breaths evoked a progressive increase of Phr and EI from bre...
متن کاملRespiratory responses to stimulation of afferent vagal fibres in rabbits.
In the experiments with 43 paralyzed rabbits ventilated artificially under general anaesthesia with halothane the effect of electrical stimulation of the central end of the vagus nerve on respiratory pattern was investigated. The analysis of respiratory responses to varying parameters of stimulation, and comparison of results with the experiments in which stimulation of pulmonary receptors was ...
متن کاملMonosynaptic Reflex Response of Spinal Motoneurons to Graded Afferent Stimulation
Monosynaptic reflex response of spinal motoneurons to graded afferent volleys has been studied in natural populations and in a representative sample of individual motoneurons. By analysis of input-response relations certain of the requirements for initiation of reflex discharge have been defined. Initation of motoneuron discharge by monosynaptic afferent excitatory volleys results from the deve...
متن کاملShort-latency phrenic response to electrical vagal stimulation in rabbits.
The response of the phrenic motoneurones to single shock stimulation of- afferent vagal fibres during inspiration was studied in rabbits. The rabbits were anaesthetized with halothane, paralysed, artificially ventilated and bilaterally vagotomized. To improve the detection of the response on the non-integrated efferent phrenic activity in the presence of background discharge, 64 to 128 single r...
