Abstract
In many epileptic attacks the patients suffer from a variety of abnormal sensations or unconsciousness. Up to now, the attention seems to have been focused exclusively on those phenomena that precede or follow upon the generalized seizure, because they can tell about the localization of the lesion that has initiated the attack. Most of these events are probably of cortical origin. Since the well-known activation of epileptic processes with intermittent photic stimulation (11, 29, 34) also influences other cortical areas than the visual, the light-evoked responses must spread diffusely within the brain. That this is the case was shown by the extensive studies of Hunter and Ingvar (23) who not only traced the “non-specific” visual responses in the brain stem and thalamus but also concluded that the visual cortex might control the conduction of the light-evoked responses in subcortical structures (24).
