[The neuronal electrical responses of the superior cervical ganglion in the rabbit to nociceptive skin stimulation].
The patterns of tonic activity in the neurons of rabbit superior cervical ganglion at rest and during noxious stimulation of the skin were studied using intracellular recording. According to reflex changes in the activity patterns, all neurons studied were classified into three groups. Cardiac rhythmicity is more pronounced in the neurons of the second type than in those of the first type. The magnitude of the cardiac rhythmicity in both types of neurons was reduced after noxious stimulation of the skin. In the third type of neurons the cardiac rhythmicity was absent. In some neurons slow excitatory and inhibitory postsynaptic potentials appeared resulting from skin stimulation.
