the probabilistic reversal learning task and tested on the ACC manipulation in this task. 7 JAWS-GFP animals were excluded from the study due to poor or mis-located JAWS expression. In the group that was tested on both tasks, 1 Jaws and 2 control animals were lost from the study before optogenetic manipulation on the probabilistic reversal learning task due to failure of the LED implants. The resulting group sizes for the optogenetic manipulation experiments were as reported in the results section.
