Electrical cochlear stimulation produces faster, larger neural responses than acoustic stimulation
Evidence
The amplitude of wave eV was larger than an acoustically evoked ABR amplitude, and latency which occurs approximately 3.6 ms after the onset of the stimulus is shorter because the electrical stimulus directly activates the neural pathway (Starr and Brackmann 1979 ; Pelizzone et al. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1451
Figure 1a shows the morphology of the eABR and the BIC of subject S5 with reference electrode L4 and probe electrode R1, where the electric artifact was already removed (Hu et al. 2015 ). In general, wave eI was not observed due to the stimulation pulse artifact from the implant. The amplitude of wave eV was larger than an acoustically evoked ABR amplitude, and latency which occurs approximately 3.6 ms after the onset of the stimulus is shorter because the electrical stimulus directly activates the neural pathway (Starr and Brackmann 1979 ; Pelizzone et al. 1989 ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 1469
