Monkeys with OFC lesions failed to show differential pupil responses during the CS and trace periods (main effect of CS, F (1,3) = 2.46; p > 0.05 for the CS period; F (1,3) = 4.65; p > 0.05 for the trace period), although they showed marginally significant pupil responses during the reward period ( F (1,3) = 8.83; p ≈ 0.0589).
