Figure 3.

Effect of inactivation of vlPFC on the standard and probe four-block variable sequencing task. Graph shows the mean accuracy per block for subjects after infusion of saline (dashed line) and musbac (solid line) into the vlPFC. Individual data points are presented as a unique colored symbol, where musbac data points are filled, while saline datapoints are hollow. A, For the standard task, inactivation of vlPFC impaired performance only in the third and most difficult block of the task. B, On the probe task, inactivation decreased accuracy across all blocks. Inactivation also increased the number of errors performed on incorrect trials in the probe task.
