I want to know the answer to the following question:
The precise way this temporal structure helps code for pitch at higher levels is based on what?
All the background I'm provided with is that "At least one model shows that a temporal delay is unnecessary to produce an autocorrelation model of pitch perception, appealing to phase shifts between cochlear filters; however, earlier work has shown that certain sounds with a prominent peak in their autocorrelation function do not elicit a corresponding pitch percept, and that certain sounds without a peak in their autocorrelation function nevertheless elicit a pitch.". Is that enough to answer the question?
