Аннотация:A quantitative evaluation has been made of methods designed to identify the intracranial sources of scalp recorded potentials. The scheme presented models the sources as equivalent dipoles and allows for the detection of multiple sources. The head is modeled by both homogeneous and inhomogeneous spheres. The results establish the technical feasibility of finding equivalent dipoles in the visual cortex for human visually evoked scalp potentials (VESP's).
