Noradrenergic activation of the BLA modulates consolidation of object-in-context recognition memory. (A) Enhancing effects of post-training intra-BLA infusions of norepinephrine on 24-h object-in-context recognition memory. Saline-infused controls displayed no evidence of memory of 3 min of training. The retention performance of the group given 0.3 μg of norepinephrine was significantly better than that of the saline controls. Data are presented as discrimination index (mean ± s.e.m.; see main text). (B) Impairing effects of post-training intra-BLA infusions of propranolol on 24-h object-in-context recognition memory. All groups received 10 min of training. Saline-infused controls displayed significant memory and propranolol produced dose-dependent impairment of memory. The performance of all three propranolol groups differed significantly from that of the saline controls. *P < 0.05; **P < 0.01. N = 9–15 rats per group.
