D.C.-Potentials in the Auditory Evoked Response in Man

摘要: While the conventional auditory evoked response is mainly related to onset of stimuli and/or their cessation (off-effect) during prolonged sinusoidal stimulation, a marked d.c.-potential could be recorded by means special d.c.-recording set-up in both animals and man. Here, precautions had taken avoid polarization—artefacts originated electrodes (Beckman-type). Those difficulties have been overcome clearly reproducible records d.c.-potentials man obtained our Institute. These depend upon stimulus intensity duration. They show addition interaction with other sensory modalities such as visual ones. A comparison time course interval PST-histograms from single units colliculus geniculate prove intramodal specific nature. The importance for “objective” audiometry demonstrated.
