Abstract

A method for monitoring the response of a nervous system of a body to a stimulus. The method comprises collecting a set of voltage measurements between selected areas on a surface of the body whilst current is being passed between selected regions of the surface of the body. The set of voltage measurements is collected over a predetermined measurement period, the predetermined measurement period is based upon a time after application of the stimulus, and the collected voltage measurements are compared with reference measurements to determine normal or abnormal response of the nervous system.
