[Alteration of the functional organization of the lateral geniculate body after injection of tetanus toxin into it].

Changes in neuronal activity of the lateral geniculate body were studied in cat under conditions of the formation of a generator of pathologically enhanced excitation after local injection of tetanus toxin into this nucleus. To evaluate the changes, an analysis of interdischarge intervals histograms of spontaneous activity and poststimulation histograms were performed. A conclusion was made that as a result of the tetanus toxin injection the inhibitory mechanisms of many relay neurons became destructed, producing substantial changes in their discharge patterns.
