[Effect of stress-inducing factors on monkey behavior. II. Hormonal indices and their relation to behavior in the modelling of emotional stress in hamadryas baboons]

Abstract

The behavioural and hormonal indexes of adult males Papio hamadryas have been examined under condition of immobilized stress. The intercommunication between the hormonal status of the individual and its position in the hierarchical structure of the group is marked. The leader of the group possesses the mostly constant hormonal content during the different periods of the stress. The equal speed of reconstruction of hormonal concentration and behavioural indexes has been found. The different types of correlation between the level of adrenaline, cortisol and testosterone secretion and the frequency of aggressive behaviour have been observed.
