Figure 3.

Examples of correlograms (left column), distributions of the decision variable (middle column), and correlation sensitivity curves (right column) for three AN fibers arranged from low to high CF. CF and SR are indicated in the left corner of each panel in the first column. The stimuli were eight frozen broadband (0.1–30 kHz) noise tokens with 18 values of mutual normalized correlation (ρ). Filled circles in the right column are d′ values for ρ = 1, 0, and –1 and correspond to the curves shown in the left and middle columns. Open circles show d′ for intermediate values of ρ. The horizontal dashed lines in the panels of the right column indicate d′= 1, and the vertical dashed lines indicate the decorrelation threshold θ.
