Evoked potentials of self-interrupted Jacksonian epilepsy.
We describe a female case of Jacksonian epilepsy who can interrupt the spreading of her march by grasping her fingers firmly with her right hand. Neurophysiologically, Somatosensory evoked potential (SEP) was remarkably decreased in amplitude with pressure stimulation similar to her method. Such a change in SEP was observed also in a healthy subject. Accordingly, it is suggested that the stimulation only to the proprioceptor of fascia suppresses the activity in the cortex.
