[Properties of rhythmically active neurons of lymphatic heart center of the frog Rana temporaria].
During extracellular recordings of the activity of spinal neuronal units in situ, it was found that rhythmically active neurons respond to antidromic stimulation of ventral roots (X, XI), which include motor heart fibers. The amplitude of the responses of these motoneurons to continuous rhythmic antidromic stimulation exhibits slow rhythmic oscillations, reaching the lowest value to the onset of the spontaneous spike potentials. In isolated spinal cord preparation (from VIII segment), rhythmic activity of the center studied was preserved, which indicates the capacity of central structures to automatic activity.
