Abstract
The urgency of the development and improvement of methods for studying the functional state of users of computer technology is growing in parallel with the growth of their negative impact on the main targets - visual and neuropsychic functions. Therefore, the aim of the study was to study the processes of perception of rhythmic light incentives and induced electrical activity of the visual cortex during a computer load. The study was conducted with the participation of clinically healthy students ( n = 182), who determined the critical fusion frequency of flashes and recorded rhythmic cortical evoked visual potentials during a computer-assisted visual load. To assess the nature and duration of use of computer students, as well as determining the presence and severity of computer dependency, a survey was conducted. Various types of perception of light flashes and changes in the rhythm assimilation reaction under the influence of a computer load are revealed. The data are discussed taking into account the rhythmic processes of the brain. A conclusion is drawn about the weakened, stable and strengthened types of response of oscillatory neural mechanisms to computer visual loads.
