Receptive fields of an auditory nerve fiber to acoustic (AS), electric (ES) and combined (EAS) stimulation. The data demonstrate that in the EAS mode, the responses are often combinations of the acoustic and the electric responses with no significant distortion of the frequency response area. FRA = frequency response area (acoustic stimulation). PSTH = poststimulus time histogram. Figure from Tillein et al. 2015.
We are one of the few labs internationally that can record auditory nerve activity with cochlear implants.
