[Driving phenomenon in neurons of the spinal center of frog lymph hearts].
Bioelectrical activity of motor axons of the lower lymphatic hearts was recorded in frogs. When the 5th and 6th dorsal roots were stimulated at a frequency lower than the spontaneous frequency, artificial bursts of motor impulses were usually produced together with spontaneous impulses. Latency of artificial impulses depended upon the time of stimulation in the interburst interval. When the same roots were stimulated at a frequency higher than the spontaneous rate, only motor impulses corresponding to the artificial frequency were observed. The latency of these artificial impulses was 100--160 msec.
