[Characteristics of the evoked electrical reactions of the nucleus lateralis posterior in the rabbit thalamus and their dependence on cortical and reticular formation function].
The electrical responses of n. lateralis posterior of the thalamus (nLP) to light stimuli of different intensity were recorded in alert rabbits, and their interrelationships with the reactions of retina, superior colliculi and visual cortex were analysed. The retina rather than superior colliculi appeared to play a major role in afferent supply of nLP in rabbit. The organized mechanism of facilitating reticular control of the nLP function was shown, with the adrenoreactive mechanism playing the most important role in the reticular influence. The inhibitory influence of visual and sensomotor cortical areas upon neuronal mechanism of nLP forming the responses to photostimuli, was revealed. The effects of visual cortex were the most expressive and stable.
