The bradycardia evoked by electrical stimulation of the peripheral cut end of the rabbit vagus nerve is mediated by both myelinated and non-myelinated fibres. The purpose of this study was to assess the effects of non-myelinated fibres on heart rate in the rabbit using selective electrical stimulation techniques. In 8 rabbits selective activation of(More)
Previous studies from this laboratory have established that electrical stimulation of non-myelinated axons in the rabbit vagus nerve produces a bradycardia which is unaffected by the nicotinic ganglion blocker hexamethonium. The present study was undertaken to determine whether this effect is mediated by afferent or efferent axons. A unilateral supranodose(More)
