[Postsynaptic potentials of trigeminal nerve nucleus motor neurons evoked by stimulation of the dental pulp in cats].
PSPS of the digastric and masseter motoneurons evoked by stimulation of the upper canine pulp of the ipsi- and contralateral side were studied in the nembutal-chloralose anesthetized cats. Stimulation by single volleys of tooth pulp evoked EPSP and action potentials in digastric motoneurons (latency for ipsilateral pulp was 4.0-5.5 ms, for contralateral--7.0-8.0 ms) and IPSP in masseter motoneurons (latency for ipsilateral pulp was 3.5-4.2 ms, for contralateral--3.8-5.5 ms). All PSPS were polysynaptic.
