Frequency of spontaneous impulsation in rat cervical symphetic nerve preganglionic fibres after chemical sympathectomy.
The frequency of spontaneous activity of single preganglionic fibres in the cervical sympathetic nerve of sympathectomized and intact animals was compared, and was found to be higher in the sympathectomized group, averaging 5.9 +/- 1.4 pulses per sec, compared with 2.3 +/- 0.5 in the control group.
