Figure 11.
BD obtained from NDFs (A), composite curves (B), and both together (C) for all LL (red) and IC (blue) data. The BD is graphed as a function of CF (circles) or DF (inverted triangles). Each symbol represents one neuron. The white and the dark gray patches show the approximate ethological ITD ranges for high (1 kHz, smallest range) and low (250 Hz, largest range) frequencies, and the black hyperbolic solid and dashed lines indicate the π-limit and 1/4 π-limit, respectively. The legend entry CFXX followed by two numbers indicates the number of neurons in the IC and LL for which CFs where available (first number) and the total number of neurons (second number). The difference between these two values is the number of neurons for which we did not obtain a CF but used the DF instead.
