[The auditory, somatosensory and visual evoked potentials in the oto-neurologic diagnosis (author's transl)].

The theory of a signal averaging system for noninvasive electro-diagnosis and the measurements of auditory, somatosensory and visual evoked responses have been explained. This diagnosis as a powerful new tool has been demonstrated in different patients with cerebellopontine angle tumor, hydrocephalus, brain stem vascular disease, encephalomyelitis and for determining the hearing threshold in infants.
