Spectrotemporal matching of monaural inputs to NL neurons. (A, C, and E) Example left and right STAs for three NL neurons. (B, D, and F) Parameters of gammachirp fits (f₀, c, τ) to left and right STAs of NL neurons. (G) Comparison of best ITD of NL neurons computed by a cross-correlation model when left and right IF glides are as measured or made to match. The difference indicates the amount of the best ITD that is because of differences in the IF glide. In four neurons, removing the mismatch resulted in a large difference between measured and predicted ITD. The parameters of the gammachirp fits of these four neurons are indicated by black circles in B, D, and F.
