Systems for detecting one or more central auditory potentials include an implantable cochlear stimulator configured to be implanted within a patient and to generate a stimulation current in accordance with one or more stimulation parameters, a signal processing unit configured to be located external to the patient and to be communicatively coupled to the implantable cochlear stimulator, and one or more electrodes configured to be removably coupled to the signal processing unit. The electrodes are configured to detect the one or more central auditory potentials and the signal processing unit is configured to process the detected central auditory potentials.
