What is Electrocochleography (EcoG)?

EcoG is a measure of the electrical potentials within the auditory system. As the auditory system is stimulated by an acoustic signal, it causes a change in the electrical potentials of the sensorineural mechanism that can be monitored through electrodes placed on the head and in the ears. This test is used to identify cochlear/endolymphatic hydrops for patients with dizziness.
