Abstract:"Typological peculiarities of the behaviour of adult white male rats were determined using the 'emotional resonance' test, i. e. reaction of avoidance of the signals of the defensive state of the other animal of the same species (vocalization, release of pheromones, motor excitation). The rats developed a conditional motor food reflex, and then they were subject to a stress of inescapable pain reaction. Judging by the preserved conditional food reflexes, the rats which avoided the partner's pain screams proved to be the most stable. The rats unable to determine the dominating motivation and incessantly running from one section of the chamber to the other are the least stable. The highest level of catecholamines was found in the blood of the latter group. The sensitivity to the partner's signals of defensive excitation correlates with the degree of such shifts, occurring under the stress influence as the content of noradrenaline, dopamine and 5-oxyndolacetic acid in the tissues of the brain, the state of the lipid component of the cerebral membranes. According to the obtained results the stress reveals the individual peculiarities of the physiological functions which are not obvious without the stress influences. The animals, highly sensitive to the signals of the partner's emotional state, possess high resistance to the action of the most various stresses. It can be assumed that thanks to such stability natural selection preserved the capacity for zoosocial 'empathy'--phylogenetic predecessor of human altruism"
