    Abstract:
    A practical new method for the clinical examination of the auditory pathway from the ear to the brain is presented. Averaging of 4000 stimuli produces a graphic image of evoked potentials in the brainstem and both cerebral hemispheres. We report the results of examination with this new method in 60 normal ears of 30 healthy young people to determine the normal pattern of cerebral processing of evoked auditory signals 5 to 15 milliseconds after stimulating the ear. It is concluded that the examination is useful for studying auditory signal processing in the brain. It also demonstrated that the primary and secondary auditory cortexes are not the destination of the auditory pathway, but relay stations.
