Trauma could occur 7 to 13 mm from the round window, where the outer cochlear wall is splayed, and this directed the array at the basilar membrane.
The filter bandwidths were similar to the frequency response characteristics of the cochlear basilar membrane.
One possible explanation was that neuronal firing for sound was correlated across small groups of neurons because of phase differences, as a result of the traveling wave along the basilar membrane, as illustrated in Figure 37, and this pattern was not reproduced with electrical stimulation.
The fine patterns of responses are due to neighboring fibers [178] reproducing the phase changes seen from sound waves traveling along the basilar membrane (Figures 37 and 39) [179-181], but they do not occur for an electrical stimulus.
The implications of insertion trauma for subjects with residual hearing may be even more serious than for profoundly deaf CI users, since damage to the organ of Corti could severely affect the transmission and distribution of acoustic vibration along the basilar membrane.
One contact of each pair was oriented on the medial side of the electrode carrier toward the position of the spiral ganglion, and the second contact was oriented on the upper surface of the carrier toward the osseous spiral lamina or basilar membrane.
In general, if the goal is to estimate the characteristic frequency location for stimulating sites along an electrode array, then logically, the zero or reference point for measurement should be the beginning of the basilar membrane.
Most of them design the cochlea-mechanical analyzer just like real basilar membrane it is like membrane with different cross-section along its length.
The basilar membrane is possible to simulate also by an array of resonators with mutual coupling.
