Figure 7. OFC represents task structure information beyond outcome features.

a) With selectivity for action and outcome features removed, pseudoensembles drawn from control session neurons achieved significantly better classification performance than eNpHR pseudoensembles. Error bars indicate the SEM in classification accuracy across 250 random pseudoensembles; dashed horizontal line indicates chance level for classification. Asterisks indicate significant differences between control and eNpHR pseudoensemble classification performance (paired t-tests, corrected for multiple comparisons). b) For control data, errors in classification were concentrated along the minor diagonal from the lower-left to upper-right corner, corresponding the unchosen action and outcome combination that accompanied the option rats chose. This pattern was substantially weaker in eNpHR sessions.
