[Comparative study of the discharges of sympathetic and parasympathetic nerves during stimulation of the visceral field of the limbic cortex].
Comparative characteristics of parasympathetic responses in pelvic nerve and sympathetic responses in lumbar white communicating rami to stimulation of dorsal and ventral parts of anterior, visceral area of limbic cortex were studied in anesthetized and immobilized cats. Single shocks or short trains of stimuli of the area 25 in limbic cortex evoked a complex response in pelvic nerve, consisting mostly of three waves: the late waves II and III of the parasympathetic discharge with a mean latency of 63.3 and 180.4 msec, and a mean magnitude of 11.0 and 16.7 microV, resp. A short latency component was rarely observed and its latency was about 15.9 msec. The EPs in pelvic nerve and white rami had the lowest threshold in stimulation of the ventral part of area 25. Comparative study of the excitability-recovery properties of cingulo-parasympathetic and cingulo-sympathetic responses revealed a long-lasting inhibition of the test responses for 2000 and 900 msec, resp.
