[Changes in the level of seizure readiness of KM strain rats undergoing systematic stimulation by light and sound]

A possibility of reflex change in the rats seizure activity level of KM line in which an intensive sound causes epileptiform seizures has been studied. Interrupted light stimulation (non-specific for the given form of seizures) does not cause any seizures. It has been found however that the initial presentations of light stimulation favour the increase of seizure activity level in rats. Prolonged systematic stimulation by an intensive sound or by the light + sound complex cause a gradual drop in the seizure activity level. The light cancellation following a prolonged systematic stimulation by light + + sound causes a short-term rise in the seizure activity level.
