Summary Symptomatogenic areas for ictal laughter have been described in the frontal and temporal lobes. Within the frontal lobe, gelastic seizures have been recorded from the cingulate gyrus. Electrocortical stimulation of the cingulate gyrus as well as the superior frontal gyrus induced laughter. We describe a patient whose gelastic seizures were associated with electrographic ictal activity in the mesial aspect of the right anterior frontal gyrus. The symptomatogenic area for ictal laughter in the frontal lobe may reside in the superior frontal gyrus.
