Red'ka, O. Mayorov] The correlation between alpha-frequency EEG oscillations and the state of visual afferentation is unquestionable. However, the question of the presence of the true alpha rhythm in the case of visual dysfunctions is controversial. We performed an autocorrelation analysis of the rhythmic parameters of alpha activity in the occipital cortical areas of children, teenagers, and youths (age from 8 to 20 years) having different visual acuity. Five types of rhythmicity of alpha activity, the character of which was dependent on the shaping time of visual dysfunctions, have been differentiated. We found that congenital bilateral visual dysfunctions determine significant decreases in the periodicity and stability of alpha activity; a low-steady aperiodical α-like activity was observed in 45% of the recpective cases.
