ELICITATION of epileptogenic activity has been reported in response to such simple stimulus conditions as touch, intermittent and constant light, sounds, movement, vestibular, and visceral stimulation. In addition to simple stimulation of a primary sensory modality, certain behavioral sequences have also been correlated with the onset of seizure activity. Examples include listening to music and viewing patterns, as well as such language activities as reading, writing, and speaking.1 In a representative case report of this type, Ingvar and Nyman2 have reported a patient with petit mal seizures in whom electrographic abnormalities occurred with high frequency in association with attempts at calculation. It was found that not only calculation but also the instruction to be ready to perform calculation were effective elicitors. Geschwind and Sherwin have recently reported a case in which seizures could not only be triggered by reading, but by writing and speaking as well.
