Chronic experiments on rabbits have shown that visual cortex stimulation resulted in intensified lipid peroxidation in the retina with the parallel decrease of electroretinogram amplitude parameters. The transsection of the optic nerve resulting in the elimination of retinal corticofugal inputs diminished the accumulation of lipid peroxidation products in(More)
It has been demonstrated in chronic experiments on wakeful rabbits that the posterolateral nucleus of the thalamus exerts tonic and phasic facilitatory influences on the formation of responses of the visual cortex elicited by a light flash. The tonic influences were expressed in an increase in the amplitude parameters of the responses of the visual cortex(More)
It is shown that in nembutal anesthetized cats, a single stimulation of motor cortex (MC) causes a response in lateral geniculate nucleus (LGN). The development of this response had a conditioning effect on the LGN response evoked by stimulation of the contralateral superior colliculus (SC), markedly inhibiting it. The degree of this inhibition depended on(More)
Information is known to reach the visual cortex [3, 5, 6, 8] along three main channels of communication: the classical retinogeniculocortical (RGC) and transcallosal (through the corpus callosum) and also the retinotectothalamocortical (RTTC) channel (through the superior colliculus; SC). In previous investigations [2] the writers showed that the RGC and(More)
It has been demonstrated in awake rabbits that stimulation of the visual cortex by a solitary pulse of electrical current leads to the formation of a short-latency response in the superior colliculus. The formation of this response is suppressed when a light stimulus precedes it. At the same time, a conditioning solitary electrostimulation of the visual(More)
The mesencephalic reticular formation (MRF) has a marked effect on function of the lateral geniculate body (LGB) [2, 3, 5, 6, 8, ii, 15]. This effect is mediated through the presence of direct connections of MRF with LGB [4, 8]. However, it has recently been suggested that influences of MRF on LGB may be transmitted also through the thalamic reticular(More)
Well-marked rhythmic activity, both fast and slow, can be recorded in all parts of the central visual system [I, 3, 6, 9, 12]. Genesis of the s-rhythm is of particular interest to investigators studying the formation of slow activity [4, 9, 12], whereas the genesis of the other components of the EEG in both cortical and subcortical visual structures as a(More)
Relations between different parts of the central visual system and, in particular, the lateral geniculate body (LGB) and superior coUiculus (SC), have attracted the attention of research workers for a long time. However, whereas geniculocollicular relations have been studied in sufficient detail, collicnlogeniculate relations have received much less(More)
The tonic influence of the superior colliculus (SC) on the formation of visual evoked responses of the sensomotor cortex (SMC) was demonstrated in experiments on conscious rabbits. The influence of SC on the function of SMC was found to be realized with the involvement of tectothalamocortical (through the nucleus lateral is posterior thalami — NLPT)(More)
In acute experiments on anesthetized cats it was shown that a single stimulation of the ocular muscles leads to unambiguous changes in the formation of the negative and positive components of the evoked response of the lateral geniculate nucleus to the presentation of a light stimulus. It was established that the nature of the muscular influences on the(More)
