title: [Reactions of arterial pressure to sciatic nerve A-fiber impulses in decerebrate and spinal frogs].
abstract: Contrary to mammals, cutting of the spinal cord on the caudal part of the first segment in high-decerebrated nonanesthetized frogs does not evoke any statistically significant changes in blood pressure or lead to the depression of pressor responses to sciatic nerve A fibres stimulation. The intensity of the responses remains unchanged following cordotomy when stimulation frequency is low and increases when stimulation frequency is high. The results are believed to corroborate the conception on the predominant role of spinal shock in the depression of somato-sympathetic reflex reactions in cordotomized mammals.
