Pre-activation pitch matches were lower than would be estimated by a spiral ganglion pitch map. Deviations were largest for stimulation below 240掳 degrees and smallest above 480掳. With experience, pitch matches shifted towards the frequency-to-electrode allocation. However, no statistically ...
Speech recognition increased with deeper insertion, reaching an asymptotic level at 21.6 or 26.4 mm depending on the frequency-place map used. Başkent and Shannon [J. Acoust. Soc. Am. 116, 3130–3140 (2004)] showed that speech recognition by implant users was best when the acoustic input ...

For CI-alone users, default frequency filters aligned closely with the spiral ganglion map for deeply inserted lateral wall arrays. For EAS users, default frequency filters produced a range of mismatches; absolute deviations of ≤ 6 semitones occurred in only 37% of cases. Participants with ...
aAlthough the place code of tone frequency, or tonotopic map, has been widely accepted in the auditory cortex, tone-evoked activation becomes less frequency-specific at moderate or high sound pressure levels. 虽然口气频率地方代码或者tonotopic地图,在听觉皮层广泛被接受了,口气被召唤的活化作用变得较不频...
Our findings are consistent with the hypothesis that diplacusis is due to an altered cochlear map. Map changes can lead to altered pitch, but the size of the pitch change is also affected by neural synchrony. Our data show that the cochlear frequency-place map is not fixed but can be ...

(B) The firing-rate map for each of the 16 mutant place cells from the session with the second highest coherence. Again, the maps are arranged in descending coherence order. By visual inspection, it seems clear that the firing fields of wild-type place cells are crisper than those of tran...
In this article, we propose a method, based on cochlea imaging, to determine the cochlear place-frequency map. We evaluated the effect of frequency-place mismatch on speech perception outcome in subjects implanted with 3 different lengths of electrode arrays. A deeper insertion was responsible for...
