CHARACTERISTICS OF THE BRAIN ELECTRIC ACTIVITY IN COGNITIVE IMPAIRMENT

Abstract

Based on the analysis of joint recurrence plots of the brain’s response to functional load in the form of rhythmic photostimulation, quantitative indicators of changes in the bioelectrical activity of the brain of patients with moderate cognitive impairments were revealed before and after the method of therapy associated with the formation of stable functional brain connections. It has been shown that such therapy, leading to an improvement in the condition of patients, correlates with changes in the indicators of joint recurrence plots of the bioelectrical activity of the brain and photostimulus.
