Figure 4. Neuronal responses are related to the behavioral performance of monkeys.

Cumulative distributions of the ratios computed between the normalized responses to a given tone in false-alarm trials and in correct trials. For both S1 and S2, ratios were computed between the no-go tone in false-alarm trials and in correct trials (black curves). For S2, ratios were also computed between the no-go tone in false-alarm trials and the go tone in correct trials (gray curves). Results obtained from the 3 kHz and 1 kHz tone were pooled.
