Lesions of either anterior orbitofrontal cortex or ventrolateral prefrontal cortex in marmoset monkeys heighten innate fear and attenuate active coping behaviors to predator threat.

In particular, the antOFC lesioned group displayed a strong trend for increased distance from the snake [One-Way ANOVA, F (2, 11) = 3.90, p = 0.052; post-hoc pairwise comparison for “control” vs. “antOFC” p = 0.018] (Figure 7C ), both antOFC and vlPFC groups avoided staring at the snake [One-Way ANOVA, F (2, 11) = 5.35, p = 0.024; post-hoc pairwise comparison for
