[The relationship between catecholamine levels, tyrosine hydroxylase activity in the brain and the rank of male mice in a population hierarchy].

This study was aimed to investigate processes of biosynthesis in catecholaminergic system of male mice with genotypically determined dominant and submissive behaviour in population and their F1 offsprings. F1 inherited not only high capacity for dominance but also high tyrosine hydroxylase activity and catecholamine levels in striatum and hindbrain. It has been concluded that the high level of biosynthesis in catecholaminergic neurons is necessary for coordination of neurochemical systems involved in the regulation of genotypically determined dominant behaviour in male mice.
