title: [Changes in the postsynaptic responses of spinal cord motor neurons against a background of rhythmic stimulation of the locus coeruleus].
abstract: Influences of locus coeruleus rhythmical stimulation on the postsynaptic reactions of spinal motoneurons were studied in chloralose anesthetized cats. IPSPs evoked by flexor reflex afferent (FRA) stimulation were inhibited, but EPSPs evoked by FRA and PSPs evoked by low-threshold muscle afferents stimulation were unchanged under these conditions. The inhibition of IPSPs disappeared in reserpine-pretreated animals. Both IPSPs and EPSPs evoked by FRA stimulation were diminished also during rhythmical stimulation of nucleus reticularis pontis oralis. However this effect was not of monoaminergic nature because it was present in reserpine-pretreated animals.
