Reported are three patients with ictal monoparesis of an arm. In the hemisphere contralateral to the monoparesis, ictal and interictal epilepti-form discharg es were observed in the centroparietal area, and a well-circumscribed lesion wa s commonly present in the primary arm somatosensory area (SI). In the presence o f an SI lesion, the epileptic activity at the sensorimotor area could lead to se lective or predominant activation of the inhibitory motor system.
