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)
The electroretinogram oscillatory potentials have similar general configuration and frequencies. Under the conditions of experimental dystropia of the retina and also after glycine administration, suppression of the oscillatory potentials formation in retina is accompanied by suppression of the evoked responses formation in the LGB, superior colliculi,(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)
Significant changes in the formation of electrical activity rhythms have been revealed in the lateral geniculate body, superior colliculus and visual cortex during section of one half of midbrain operculum in cats anesthetized with nembutal. It was determined that all changes in slow activity generation in the lateral geniculate body, superior colliculus(More)
In chronic alert rabbits, both transient and sustained influence of the nucleus lateralis posterior upon visual cortical responses to the light flashes, were shown. The transient influences were revealed by an increase of the responses amplitude in the nucleus lateralis posterior and by a decrease of the amplitude during the K depression. The sustained(More)
In alert rabbits, stimulation of posterior hypothalamus induced short-latency responses in the visual cortex and affected the formation of the EPs to light. Depending on the intervals between the stimuli, either initial extinction of the EPs (1-15 msec) or subsequent selective facilitation of its positive component with simultaneous depression of negative(More)
It has been demonstrated in chronic experiments on wakeful rabbits that the stimulation of the posterior hypothalamus by a single electrical stimulus leads to the formation in the visual cortex of a short-latency response which exerts a substantial influence on the formation of the reaction to light stimulation. Depending upon the intervals between the(More)
On alert rabbits it was shown that the stimulation of the superior colliculus inhibit visual evoked potential both of the ipsi- and contralateral geniculate body. Besides, the suppression of amplitude of the contralateral geniculate body's evoked potential was more significant than amplitude of the ipsilateral geniculate body's evoked potential. On the(More)
Dystrophy induced by intravenous injection of monoiodoacetic acid (MIAA) is often used as an experimental model of retina] pathology. It has been shown [11-15] that this pathological state is very similar to retinitis pigmentosa in man or in animals with hereditary c[egenera ,~ tion of the retina. The similarity is manifested not only in the clinical(More)
