Auditory evoked potentials in Errachidia

Auditory evoked potentials seek out a spontaneous electrophysiological response of the auditory pathways to the brain upon exposure to noise of varying intensity. The recording of AEPs is done with electrodes placed at specific locations on the skull, especially on the mastoid and in the forehead. The recorded results are represented by a curve. This recording therefore requires complex instrumentation. This test has the advantage of not requiring the collaboration of the patient and can therefore be done in newborns. However, its interpretation is difficult and requires a lot of experience. The recording of AEPs is mainly used to confirm, deny or clarify deafness in young children; and also to highlight certain lesions of the auditory nerve and auditory pathways
