Currently, the actual problem is the correction of motor, cognitive and psychoemotional disorders in physiological aging, as well as in various pathological processes that accompany aging and accelerate it. In this regard, it became necessary to search for drugs that can restore age-related disorders of the brain. The aim of the study was to evaluate the possibility of Cytoflavin as a pharmacological corrector of age-dependent disorders of the functions of the cerebral cortex during physiological and pathological, accelerated aging. The mouse sensorimotor cortex of the brain was the material for study. The transgenic male mice with HER2/neu overexpression at the age of 2 and 10 months were used as an experimental model, male wild-type FBV/N mice at the age of 2 and 18 months served as a control. We studied locomotor activity, orientational research behavior and the psychoemotional status of animals using the «open field» test and the Suok test. It was found that in old FBV/N mice, after the cytoflavin treatment, recovery of locomotor functions and orientational-research behavior is observed. Under conditions of HER2/neu overexpression after the Cytoflavin treatment, an improvement in motor functions occurs. It was also shown that the studied drug has an anxiolytic effect on both wild-type FBV/N mice and transgenic HER2/neu mice during aging. Thus, the positive effect of Cytoflavin on the dynamics of the behavior of experimental mice during physiological and pathological accelerated aging allow to suggest that in the late stages of ontogenesis, Cytoflavin restores the cerebral cortex functions and prevents neurodegeneration.
