Neurobehavioral effects of choninergic drugs in prenatal period

Abstract

Environmental toxicants, chemicals exhibiting with cholinotropics properties, and drugs – agonists and antagonists of M- and N-cholinergic receptors by acting on the developing brain of the fetus in the embryonic period of ontogenesis, cause a change the activity of the cholinergic mechanisms of the brain during critical periods of prenatal development with the subsequent disruption of the formation of different brain systems, primarily the ontogeny of nerve cells and brain neurotransmitter systems. These changes in the long term is correlated with neurobehavioral deficits from adult individuals, dysfunction of the reproductive system of adult offspring. The relevance of the study of prenatal effects of cholinergic factors on the central mechanisms of reproductive function, memory processes and learning during ontogenetic development of the organism due to the need of prevention and treatment of subsequent mental, behavioral, and sexual dysfunctions, and abnormal sexual behavior, infertility.
