Abstract: A case of an epileptic patient having had right hemispherectomy for 14 yearsis reported in this paper. A neuropsychological battery was undertaken in Sept. 1980. The tests demonstrated that the patient showed a certain degreeof disruption of non-verbral functions, such as perception and recognition ofa line and abstractive drawing and their spatial orientation. But there wasno apparent impairment in recognition and in spatial orientation of musicalrhythm, color hues and concrete objects. The left hemisphere compensateda part of the function of the right hemisphere. The patient works and livesas usual.
