[Agonistic behavior: model, experiment, perspectives].
Repeated experiences of social victories or defeats in daily agonistic confrontations led to different changes of the brain neurotransmitter activities in male mice with alternative types of social behaviour. Total activation of the brain dopamine metabolism was found in winners. Chronic defeats were accompanied by specific changes in serotonin and noradrenaline metabolism in limbic areas of the brain. Between losers and winners, significant differences were found in emotionality, exploratory activity, locomotion, level of anxiety, communicative behaviour, and alcohol consumption, as well as in immune responses and susceptibility to transplanted Krebs-2 tumour growth, gonadal function, and gastric mucosa damage. A sensory contact technique is proposed for studying the neurophysiological consequences of social conflicts.
