[Excitation of motor neurons of the nucleus of the accessory nerve in cats in response to stimulation of Deiters nucleus].

Responses of the accessory motoneurons to electrical stimulation of he ipsilateral Deiters nucleus were recorded intracellularly in cats under chloralose-nembutal anesthesia. Stimulation of the Deiters nucleus evoked monosynaptic EPSP with latency from 1.3 to 2.3 ms, maximal amplitude 5.0 mV and duration from 7.0 to 10.0 ms in accessory motoneurons. Under rhythmic stimulation the EPSP were weakly potentiated and under increase in te strength of the Deiters stimuli they easily became action potentials.
