Wistar rat pups, aged Postnatal Day 5, were trained in an olfactory associative learning task with citral odor as the conditioned stimulus (CS) and intraoral infusions of milk as the unconditioned stimulus (US). Following a 30-min training session, pups were injected with either the norephinephrine 13-receptor antagonist propranolol or the β-receptor agonist isoproterenol. Pups were tested 24 hr later for an acquired relative odor preference for the CS. Propranolol injected immediately following training impaired memory for the CS in a dose-dependent manner. This posttraining effect lasted less than 4 hr. Isoproterenol injected immediately after training also impaired memory performance, even at very low doses. These results suggest that posttraining levels of norepinephrine play a critical role in memory consolidation in the newborn, with elevations or decrements in noradrenergic activity resulting in impaired memory.(PsycInfo Database Record (c) 2022 APA, all rights reserved)
