Effects of Electrode Position on Spatiotemporal Auditory Nerve Fiber Responses: A 3D Computational Model Study

Figure 7

The incidence of spike initiation in response to 250- (first two columns) and 5,000- (last two columns) pulse/s pulse-trains. The pulse-train duration was 200 ms. The pulse-train levels were chosen to elicit onset (0–12 ms) response rates of 100, 200, and 250 spikes/s for low-rate stimuli and 100, 250, and 350 spikes/s for high-rate stimuli. An abscissa represents a spike-initiated node. The incidence (%) of spike initiation is represented by bubble size. ANF: auditory nerve fiber, SM: scala media, ST: scala tympani, SV: scala vestibuli, periph/P: peripheral node, and central/C: central node.
