[Biogenic amines in brain structures of rats of different zoo-social rank during immobilization stress]

The content of monoamines and their metabolites in different parts of the brain: mesencephalic reticular formation, locus coeruleus, sensomotor cortex was studied by high-performance liquid chromatography in rats with different zoo-social position. Content of dopamine and serotonin in the brain structures studied was found to be different in dominants and subdominants. Maximal changes of monoamines under immobilization stress were observed in dominants.
