Figure 5. In animals that learned the reversal (n=11), a change point in behavioral performance is reflected in DA signal.

Figure 5

A. Change point in behavior was defined as the point where the cumulative correct response curve deviates maximally from a straight line drawn from the origin to the maximum of the cumulative line. B. Quantification of DA signal to cue presentation (left: cue) and reward delivery (right: reward) for all correct responses made before and after the change point (rewarded trials only). For rewarded trials, cue-evoked DA is similar before and after change point. DA release to reward delivery is higher before than after change point. C. Quantification of cue-evoked DA signal for trials on which positive feedback was received (correct) and the trials in which animals could use this feedback (correct+1) before and after the change point. Before the change point, cue-evoked DA is higher on trials that immediately follow a correct response compared to trials in which the correct response is made.
