title: Characterization of the very late cardiosympathetic A-reflex in high-mesencephalic cats.
abstract: In unanaesthetized mid-collicular decerebrate cats, stimulation of low-threshold afferents running in the inferior cardiac nerve can evoke in renal nerve a long-latency reflex response, which is able to reduce or overcome the inhibition developing after the late response. The spatial and temporal summation have great importance in generating this very late response (VLR). Increasing the stimulus intensity and the frequency of the impulses, using short trains or a previous A + C tetanic stimulation of the segmental inputs considerably increased the chance of the VLR overcoming the late inhibition.
