1. In an electrical brain-contact device for sensing and mapping electrical epileptogenic discharges within the brain of the type having a dielectric base member and an array of electrical sensing contacts mounted thereon in spaced fashion with separate leads extending therefrom, the improvement comprising a radiopaque dielectric material adjacent to at least one of the sensing contacts whereby the intracranial positions of the sensing contacts of the array may readily be determined by x-ray without effect on the electrical sensing qualities of the sensing contacts.
