Abstract
An improved electrical brain-contact device for increased accuracy in determining epileptogenic foci. The intracranial device has a dielectric base member and an array of contacts mounted thereon with separate leads extending therefrom, and is characterized by radiopaque dielectric means adjacent to at least one of the contacts such that the positions of the contacts of the array may more readily be determined by x-ray. Certain preferred forms have discrete radiopaque dielectric markers in various arrangements, including sub-arrays of markers corresponding in number and positions to subsets of the contacts.
