Abstract
MR conditional needle and surface electrode assemblies. The surface electrode utilizes a disc or cone-shaped structure with a bore with a concave bottom surface for receiving a conductive gel and an insulated wire with a connector for an EEG. The needle electrode assembly utilizes a cylindrical-shaped structure and is constructed of an MR conditional material having a needle and an insulated lead wire structure with a connector for an EEG.
