IT IS NOW possible to record in humans the electrical activity generated along the auditory pathway in its course from the cochlea to the cortex using surface electrodes (Jewett). The principle employed is that of "far-field" recording and entails using a small computer to average the potentials generated-at a distance out of the background electrical noise. Approximately 1,000 to 2,000 click trials presented at 10 per second are necessary to resolve the brain-stem components.
