Electrodes, Neurologic, Evoked Potential, Auditory

Definition : Neurologic electrodes designed to obtain responses of the brain after stimulation by auditory stimuli (e.g., different tones, speech sound). These electrodes are typically non-invasive small cup-like surface electrodes which are applied to the subject at the head (e.g., forehead, scalp) using either tape or water-soluble paste. The electrodes are connected to the EP unit through a preamplifier and an electrode board allowing various channel-switching options. Reusable electrodes are available but disposable electrodes are more frequently used. Brain-stem auditory evoked potentials (BAEPs) are generally obtained by delivering periodic clicks through an earphone (typically at a rate of 11 clicks per second at 65 or 70 dB above the sensory level) which is the hearing threshold for one ear while the non-stimulated ear is masked with white noise of at least 40 dB above the normal hearing level. Auditory evoked potential electrodes are mostly used for clinical studies intended to assess the integrity of the auditory system.
