ALPHA-ACTIVITY: ELECTROENCEPHALOGRAPHIC AND PSYCHOMETRIC CHARACTERISTICS (REVIEW OF CONTEMPORARY LITERATURE DATA)
Institute of Molecular Biology and Biophysics SB RAMS, Novosibirsk
We review the recent literature data about the phenomenon of alpha-activity of the brain, the neurophysiological mechanisms of generation and distribution of electrical oscillations, with alpha activity. The results of studying the role of alpha activity in the processes of cognitive and psychomotor activity are prezented. Particular attention is paid to presenting the results of studies of inter- and intraindividual differences in the organization of alpha activity and the related strategy of cognitive activity and adaptation.
Keywords: alpha-wave activity, EEG, individual alpha peak frequency, the duration of alpha-spindles, the variability of the amplitude of alpha-spindles, the depth of the activation reaction, individual alpha band width.
