[Neurochemical nature of "congestive" excitation in brain structures during emotional stress]

The paper provides evidence for the new hypothesis of the nature of congestive excitation in the brain region during emotional stress. In the author's opinion, emotional stress-induced congestive excitation is determined by disintegration of molecular chemical properties in the brain regions, by the altered sensitivity of brain neurons to neurotransmitters and neuropeptides. The baseline molecular integration of the brain regions, its change and fixation in a steady status have been shown to be governed by special neuropeptides. Additional administration of substance P, delta-sleep-inducing peptide, beta-endorphin to stress-predisposed animals has been ascertained to normalize the chemical properties of brain neurons and to enhance emotional stress resistance in the animals.
