  • Title: [Space-time organization of the electrical activity of the human brain in a state of calm wakefulness and during the solution of intellectual tasks].
    Author: Kiroĭ VN.
    Journal: Zh Vyssh Nerv Deiat Im I P Pavlova; 1987; 37(6):1025-33. PubMed ID: 3448833.
    Abstract:
    In a series of experiments it has been shown that during solution of mental tasks of various complexity, a marked desynchronization is observed of the cortical rhythmic activity characteristic of the state of calm wakefulness. In the range of main wakefulness frequencies (alpha and beta), a significant lowering is observed of the level of spatial biopotential synchronizations. Its increase in these conditions is connected with the range of slow EEG rhythms; there exist different opinions about their functional significance in wakefulness.
