Subject: Re: pitch neurons From: Israel Nelken <israel(at)MD.HUJI.AC.IL> Date: Mon, 7 Oct 2002 13:07:22 +0100Dear Eckard and list, Just for the record, I didn't way anything about pure spectral coding inside the cochlea. My statement, as quoted by Eckard, is purely data driven. I would like however to raise another issue: why is there such a pressure to assume low-level representation (i.e. subcortical) of pitch? After all, pitch is a pretty high-level property of sounds, it is invariant to many features of the physical structure of the sounds, and it is affected by all kinds of high-level cognitive effects (e.g. capture of harmonics in streaming conditions). All of these would suggest to me that whatever is responsible for the pure representation of pitch (independent of the physical structure of the sounds) is rather high-level, rather than low-level.
