Figure 4

Estimated delay and magnitude discounting functions in patients whilst on (red) and off (blue). In the case of delay, the curves represent a hyperbolically decreasing function in which more distant outcomes are discounting. In the case of magnitudes, the increasing amounts result in decreasing marginal returns, manifest as a concave utility function. The dotted lines represent +/− 1 standard error of the mean. There is no statistical difference between on and off stimulation in either case.
