title: [Changes in the cerebral serotonin and noradrenaline levels in the brains of white rats trained with emotionally different reinforcement].
abstract: The changes in the serotonin (5-OT) and noradrenaline (NA) content in the brain of rats taught on the emotionally-positive (food) and emotionally-negative (pain) reinforcement were compared. The process of animal learning was accompanied by increase in the biogenic amine level. But when the teaching was conducted on the emotionally-positive reinforcement there was a greater increase in the 5-OT and NA level than in the case of the emotionally negative reinforcement. The process of animal teaching on food reinforcement was accompanied by an elevation of 5-OT chiefly in the cerebral cortex which apparently reflected the active functioning of the 5-OT system. An intensification of the NA system occurred in teaching the animals in the defence situation. A conclusion was thus drawn that the character of the changes in the biogenic amine level in the brain during learning depended on the emotions experienced by the animal (the emotional reinforcement utilized).
