Mean (± S.E.M.) number of Fos-positive cells in the basolateral/lateral complex of the amygdala of rats exposed to an adult male odor, littermate odor or no odor for (A) PN8 and (B) PN12 pups. Some groups had values at or near zero and are not detectable on this graph. Asterisks represent significant differences from each of the other groups (P < 0.05).
