Responses of the thalamic non-specific medial nuclei and relay ventral posteromedial nucleus neurons evoked by stimulation of the teeth pulp of A alpha and A sigma fibers of infraorbital nerve and caudal nucleus of the spinal trigeminal tract were studied in cats under thiopental-chloralose anesthesia. Three groups of neurons were revealed: low-threshold,(More)
Experiment on cats under chloralose-nembutal anaesthesia has shown that 65% responses of caudal trigeminal nucleus neurons to the activation of the tooth pulp, A alpha and/or A delta infraorbital nerve afferents were completely suppressed by conditioning stimulation of the central grey matter (CGM) by a train of stimuli (10-20) that followed with the rate(More)
Effect of the midbrain central gray matter (CGM) stimulation on neuronal responses of the thalamic ventro-postero-medial (VPM) nucleus evoked by stimulation of the tooth pulp, A-alpha, A-delta fibres of the infraorbital nerve and caudal nucleus of the spinal trigeminal tract have been studied in cats under thiopental-chloralose anesthesia. It is shown that(More)
The responses of masseter motoneurons evoked by stimulation of the low-threshold infraorbital afferents by different number of stimuli were investigated in cats under chloralose-nembutal anesthesia. It is shown that 3-4 succesive stimuli (1.2 of threshold) evoked action potentials in masseter motoneurons if their frequency was above 300/s. Stimulation of(More)
Postsynaptic potentials evoked by stimulation of three points of the superior colliculus in motoneurons of neck muscles were studied in experiments on cats under chloralosenembutal anesthesia. Stimulation of ipsilateral superior colliculus evoked EPSP with latencies ranging from 1.5 to 3.5 ms in 49 motoneurons. Stimulation of contralateral superior(More)
