Abstract

The human body is faced with stress throughout ontogeny. At the stage of intrauterine development, the mother’s body serves as a source of resources and most of the humoral factors supporting the development of the fetus. In normal conditions, maternal stress-related humoral signals (e.g., cortisol) regulate fetal development; however, distress (excessive pathological stress) in the perinatal period leads to serious and sometimes irreversible changes in the developing brain. The mother being in an unfavorable psychoemotional state, toxins and teratogens, environmental conditions, and severe infectious diseases are the most common risk factors for the development of perinatal nervous system pathology in the modern world. In this regard, the challenge of modeling situations in which prenatal or early postnatal stresses lead to serious impairments to brain development and functioning is extremely relevant. This review addresses the various models of perinatal pathology used in our studies (hypoxia, exposure to valproate, hyperserotoninemia, alcoholization), and assesses the commonality of the mechanisms of the resulting disorders and behavioral phenotypes forming in these models, as well as their relationship with models of perinatal pathology based on the impact of psychoemotional stressors.

Keywords: intrauterine development, perinatal pathology, perinatal stress, animal models, valproic acid, perinatal hypoxia, perinatal alcoholization, hyperserotoninemia
