Behavioral activation scores indicate that pups used for immunohistochemical neural analysis had significant acquisition, indicative of learning, and that any changes in Fos expression were not reflecting differences in behavior during odor–shock conditioning. (A) Pup activity before odor presentations during conditioning with either paired odor–shock presentations (post-training SAL, n = 4; NTX, n = 7) or control presentations (post-training SAL, n = 6; NTX, n = 9). Each data point represents the summation of behavior from two consecutive trials; mean ± SEM. There was no effect of conditioning treatment on pup activity before odor presentations. (B) Pup activity during odor presentations indicates that only paired presentations of odor–shock resulted in learning. SAL indicates saline; NTX, naltrexone.
