BLA inhibition impairs action-based probabilistic reversal learning in stimulus-naive animals, but does not affect initial action-based probabilistic discrimination or retention. A, Animals without any prior experience with stimulus-based learning exhibit impaired probabilistic reversal learning. B, There was no significant effect of BLA inhibition on initial probabilistic discrimination or next-day retention of the better-rewarded side/action.
