Infusion of NTX into the neonate amygdala following odor–shock conditioning yields consolidation of an odor aversion instead of a preference. Bars represent the number of choices (mean ± SEM) toward peppermint during Y-maze testing for pups that received paired presentations of odor and shock (SAL, n = 5; 0.1 μg NTX, n = 6; 1.0 μg NTX, n = 6) or control presentations (SAL, n = 5; 0.1 μg NTX, n = 5; 1.0 μg NTX, n = 5). SAL indicates saline; NTX, naltrexone. *P < 0.05.
