Mean (± SEM) A) dopamine (DA) or B) epinephrine (Epi) in the hippocampus. A) Familiar subordinate subjects had reduced DA concentrations, while their dominant opponents showed increased DA concentrations when compared to non-interacting controls. No change was seen in hippocampal DA of unfamiliar opponents. B) Dominant males exhibited elevated hippocampal Epi concentrations when challenged with a familiar opponent, but not when faced with an unfamiliar subordinate male. Means with no common superscript letters (e.g., A, B) are significantly different (P < 0.05).
