Abstract
The aim of the present work was to identify the characteristics of the physiological development of the brain and the formation of behavior in rats subjected to hypoxia on day 13.5 of embryogenesis. These animals showed delayed development and changes in nerve tissue structure in the sensorimotor cortex, along with disturbances to the processes forming normal movement responses during the first month after birth. These changes were partially compensated with age, though adult animals subjected to acute prenatal hypoxia were less able to learn new complex manipulatory movements. Alterations in nerve tissue structure and changes in the neuronal composition of the sensorimotor cortex correlated with the times of appearance of behavioral impairments at different stages of ontogenesis. Thus, changes in the conditions in which the body is formed during a defined period of embryogenesis lead to abnormalities in the process of ontogenetic development and the ability to learn new movements.
