title: Hypothalamic levels of thyrotropin-releasing hormone (TRH) in male albino mice of different social status.
abstract: Hypothalamic levels of TRH were contrasted in identified dominant and submissive (housed together for 4 days) Swiss male mice and undisturbed 'isolated' counterparts. Both dominants and submissives had significantly higher titres of this hormone than the 'isolates', suggesting that the experience of fighting relatively elevates the concentration of this factor in both winners and losers. It seems likely that titres of TRH are modified by fighting experience and these factors may alter subsequent behaviour but more investigation is needed on this topic.
