[Change in the evoked potentials in the visual centers of the rat brain following administration of tetanus toxin to the lateral geniculate body].
Changes in visual evoked potentials were studied under conditions of tetanus-toxin injection into the lateral geniculate body in rats. The main abnormality of the evoked potentials in the geniculate body was the function of a new phase of the primary response. At the same time a strong increase in the amplitude of the first negative component of the evoked response in the ipsilateral cortical visual field was observed. The results show the formation of disturbances in the relay function of the lateral geniculate body during the formation of a generator of pathologically enhanced excitation in this nucleus.
