[Photogenic epilepsy with localization of the generator of excitation in the lateral geniculate body (the phenomenon of a determining dispatch station)].

The photogenic seizure syndrome was produced in experiments on rats and cats by injection of purified tetanus toxin into the lateral geniculate body (LGB). The seizures followed light stimulus or arose spontaneously. At the intervals between the attacks every light stimulus provoked a specific photojerk. Disturbance of the inhibitory mechanisms by tetanus toxin proved to result in a rise in the LGB of a generator of pathologically enhanced excitation underlying the hyperactive determinative dispatch station causing the described photogenic epilepsy.
