Thirty minutes before a brief memory reminder (non-reinforced or reinforced), rats received systemic drug treatment or saline control. In study 1, MK-801 (0.1\u00a0mg\/kg) was administered to male rats. In study 2, propranolol (10\u00a0mg\/kg) was administered to equal numbers of male and female rats.
