Discriminability of the post-gap response. A. Percent neurons that the ROC analysis could reliably discriminate the difference between the gap stimulus and the control stimulus (ROC > 0.75). A1 neurons were much better at making this discrimination than CL neurons, where the ideal observer was able to make this discrimination on only about 60% of CL neurons. B. Analysis comparing the post-gap response to the no-gap response. Again, A1 neurons were better able to make this discrimination than CL neurons. The dashed vertical line shows the psychophysical threshold taken from a different set of monkeys (Petkov et al., 2003). C. Analysis comparing the response to the post-gap stimulus to the response to the stimulus onset. The y-axis shows the percent of neurons that were not fully recovered based on an ROC values between 0.25 and 0.75 (no difference between the gap response and the control response). A1 and CL neurons were equivalent in this recovery. Even at 256 msec gap durations, about 20% of neurons were not yet fully recovered (see Fig. 7).
