Table 1.

Percentage of recorded neurons with significant encoding of the predictive event or the outcome it predicted at any point from the delivery of the first outcome until the end of the first delay

Selectivity	Area	Predictor	Outcome	Predictor × Outcome
AO only	OFC	12	17	6
	ACC	12	11	11
SO only	OFC	6	18	8
	ACC	6	19	5
Both	OFC	1	14	1
	ACC	2	17	0

Neurons are classified according to whether they showed a significant main effect (with no significant interactions) or a significant interaction. Neurons are further divided according to whether they showed the selectivity in only one task or both tasks. None of the proportions listed in the table differed between the areas (χ² tests, p > 0.05 in all cases). Bold indicates that the percentage of selective neurons was significantly higher than that expected by chance (binomial test, p < 0.05).
