Abstract: The mechanisms of retrograde or anterograde neuronal transport ensure the migration of SARS-CoV-2 viruses to motor and sensory terminals, which can provoke significant distortions in the processes of information pattern recognition and the formation of action programs. The purpose of this study is to experimentally determine the dynamic modes of the cognitive system in patients with COVID-19. Cognitive processes are displayed in the space of parameters of sensorimotor activity when solving problems of different levels of complexity on the COGNITOM WEB platform. Patients and healthy individuals are presented with the same sets of stimuli in the same functional contexts. Covid-specific modes of information processing were manifested in a sharp decrease in the speed of cognitive processes and an increase in the number of missed target events.
Keywords: cognitive processes, information technology, digitalization, COVID-19.
