Abstract
Apparatus (10) for evoking and recording bio-potentials from a human subject and methods of use are described. The apparatus (10) includes a flexible member (18) with a layer of conductive material (12) disposed thereon for contacting a skin surface on the human subject. The dimensions and shape of the flexible member (18) are adapted for conforming contact between the conductive material (12) and the skin surface. A stimulus delivery element (28) is coupled to the flexible member (18) for delivering a sensory stimulus to the subject to evoke bio-potentials, which are detected and received through the layer of conductive material (12).
