Psychophysiological analysis of the relationship between the level of consciousness and the brain activation permitted an identification of three levels of consciousness at the transition from wakefulness to sleep. A change in the intensity and quality of involuntarily mental processes served as an index of the level of consciousness according to subjects' self-reports. It was found that a certain EEG profile corresponds to each level of consciousness under study. Data obtained showed that the lowest level of activation corresponds to a state in which a subject notes an inhibition of "internal speech", "failure of thoughts". At this case the dynamics of the EEG high frequency rhythm changes which is possibly related to the mechanism of transmission of cognitive information.
对意识水平与大脑激活之间关系的心理生理分析，使得在从清醒到睡眠的转变过程中能够识别出三种意识水平。根据受试者的自我报告，非自愿心理过程的强度和质量变化作为意识水平的指标。研究发现，每种所研究的意识水平都对应着特定的脑电图特征。所获得的数据表明，最低激活水平对应于受试者注意到“内部言语抑制”“思维中断”的状态。在这种情况下，脑电图高频节律的动态变化，这可能与认知信息传递机制有关。
