Somato-sympathetic reflex responses were studied by recording the activity of the renal sympathetic efferents following excitation of sciatic nerve A-afferents in immobilized decerebrated frogs before and during viadril-induced anesthesia. Apart from A-response reported in anesthetized frogs and consisting of excitatory and inhibitory components, in non-anesthetized frogs reflex discharge with a latency over 2 sec was revealed. Unlike the former one, this response disappeared after intravenous injection of viadril. In the same frogs intravenous injection of viadril converted pressor reflexes in response to stimulation of sciatic nerve A-afferents into depressor ones. A-response with superlong latency is assumed to reflect the excitation of those central structures that are responsible for the development of pressor reflexes to somatic A-fiber stimulation. In this respect the described somato-sympathetic A-response seems to be analogous to the very late A-response in the mammals.
