[The role of brain noradrenaline in regulating the endocrine function of the gonads in male brown rats selected for behavior].
In two groups of gray rats--nonaggressive ones, selected by the lack of aggression towards investigator, and aggressive animals--studies have been made on the relationship between noradrenaline system of the brain and the activity of pituitary-testicular system. In tame rats, less evident dependence of the gonadal activity on activating effect of noradrenaline was noted. After injection of norepinephrine, dopamine, and serotonin in the same brain region. *****were less significant in tame rats as compared to those in aggressive ones. The disturbed relationship between noradrenaline system of the brain and hypothalamo-pituitary-testicular complex is presumably one of the causes of associate changes in the reproductive system during selection for the domestic type of behaviour.
