title: [On the role of brain serotonin system in the pathway from gene to behaviour].
abstract: This paper concentrates on involvement of protein elements in the brain neurotransmitter serotonin system (key enzymes in serotonin metabolism and 5-HT(1A) receptors) in the genetic control of behaviour. The data were obtained using Norway rats selected for more that 50 generations for lack of aggressive response and for aggressive behaviour towards humans (fear-induced aggression), inbred mouse strains, and MAO A knockout mice. The review provides converging line of evidence that: 1) brain serotonin contributes to critical mechanism underlying genetically defined individual differences in aggressiveness, and 2) genes encoding pivotal enzymes in serotonin metabolism (tryptophan hydroxylase, MAO A) and 5-HT(1A) receptors belong to a group of genes that modulate aggressive behaviour.
