Video-EEG images of a boy with average IQ and self-induced seizures in the light. Waving his preferred left hand with outstretched fingers in front of his left eye in bright light triggered electroclinical phenomena. Waving the same hand away from the light source did not trigger clinical and EEG phenomena. Waving the nonpreferred hand or the examiner’s hand in front of his left eye in bright light did not trigger clinical and EEG events. (Contributed by Athanasios Covanis MD PhD.)
