Morphometric classification and spatial organization of spiral ganglion neurons in the human cochlea: consequences for single fiber response to electrical stimulation.
Bottom Line: Furthermore, we found evidence of a spatial arrangement of perikarya and their accordant nuclei along the cochlea spiral.Cathodic stimulation was found to induce stronger variations of spikes while also leading to the lowest thresholds and longest latencies.Therefore, anodic stimulation leads to a more uniform excitation profile among SGCs with different cell body size.

Mentions: Due to the phase duration ratio of 100 μs to 50 μs, the monophasic threshold currents for both electrode positions are approximately half the values of their biphasic counterparts, as can be seen in Fig. 7.
