Summary of the effects of inserting different cochlear implant electrodes into the ST with respect to the acoustic baseline. Responses were grouped within three frequency bands with relatively low (f < 1 kHz), middle (1 kHz < f < 3 kHz), and high (f > 3 kHz) frequencies. Responses are shown as the average difference within each frequency band, for each electrode condition. See the RESULTS for a description of the statistical analysis. Nucleus Hybrid L24 (HL24), Nucleus CI422 Slim Straight inserted at 20 and 25 mm (SS20 & SS25), Nucleus CI24RE Contour Advance (NCA), HiFocus Mid-Scala (MS), and HiFocus 1j (1j).
