Abstract
The present invention relates to a device for picking up biological electrical signals, and more precisely auditory evoked potentials generated by acoustic and/or electrical and/or mechanical stimulation of the cochlear, or of a portion of the auditory system in man or animal. The implantable device for measuring or picking up auditory evoked potentials comprises at least two extracochlear pickup electrodes connected to the inputs of a differential amplifier.
