Specific features of learning with nociceptive electrical reinforcement in rats of different genetic strains: role of brain neurotransmitter systems.

摘要

The interaction between neurotransmitter systems and opioid system in rats of different strains was studied during learning and emotional stress. The interaction between noradrenergic, serotoninergic, and opioid systems in the brain is the main neurochemical mechanism underlying learning reinforced by nociceptive electrical stimulation, which determine individual differences in the rate and type of learning.
