ABSTRACT

Electroencephalographic (EEG) patterns and neurodynamics of differentiation of visual stimuli in healthy subjects and those with auditory deprivation were evaluated. The connection between the number of processed stimuli, the minimum time of response, and the EEG rhythms during the information processing has been established. From EEG-patterns we succeeded to distinguish the features of visual stimuli differentiation. It was revealed that differentiation of visual information in people with normal hearing was characterized by a synchronous increase in the power of α- and β-waves in the occipital and right temporal regions of the cerebral cortex. In deaf people, the rigidity of EEG pattern dynamics, the dominance of the low-wavelength range and desynchronization of α- and β-wave capacities in the central, parietal, and occipital parts of the brain have been found. The background EEG pattern in subjects with auditory deprivation was low in amplitude, unlike the healthy subjects. Neurodynamic features were characterized by low speed neurodynamic indicators.
