K - complexes as a marker of working memory during sleep upon restoration disturbed activity
K - complexes as a marker of working memory (WM) during sleep upon restoration disturbed activity. In order to prove the possibility of extracting information from WM during sleep, the experiment must be constructed is used when waking up. We have developed such a form of experiment in the form of continuous psychomotor activity, the monotonous nature of which quickly caused short-term episodes of falling asleep, followed by spontaneous awakening.
We have shown that spontaneous recovery of psychomotor activity after short-term episodes of sleep, with an EEG picture of the 2 stage of sleep, is accompanied by the appearance of EEG patterns in the form of a K-complex. Statistical analysis showed a significant increase in the probability of the appearance of the K-complex before the moment of awakening.
In the background, after the appearance of K-complexes almost the same EEG as before the appearance of K-complexes. In the case of the appearance of K-complexes before pressing the pedal high-amplitude forms of EEG and alpha rhythm appear before pressing the pedal
