Cochlear nucleus neurons need wide bandwidths and multi-stage convergence to entrack pitch

Evidence

Several CN neuron types integrate over wide frequency regions (Godfrey et al. 1975 ; Winter and Palmer 1995 ): partials that are resolved at the level of the AN may be unresolved in these CN populations. The autocorrelogram-like display in the dominant ISI hypothesis sums across frequency channels (Cariani and Delgutte 1996a , 1996b ): for such an operation a wide bandwidth would be beneficial. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4494
