The design and summary of results of an overtraining experiment [58] showing that rats learn context fear, albeit slowly, when the BLA is shutdown by direct infusions of the GABA agonist muscimol. Despite overtraining, rats that learn with a functional BLA needed the BLA to express fear. However, rats that learned without the BLA did not need the BLA to express fear.
