We also measured the EEG power spectra (Extended Data Fig. 8a–d) and found a weak negative correlation between peak clearance and delta (0.5–4 Hz) power (Extended Data Fig. 8e), implying that the deeper the sleep, the lower the clearance....
Closed-loop transcranial brain stimulation during sleep: EEG-informed, phase-specific targeting of human slow oscillations with single-pulse TMS Sleep helps to stabilize long-term memories, possibly through the temporal synchronization of neuronal activity in different brain regions. Intracranial stimulation...
The team also recorded electrical brain activity during sleep with EEG. The results showed that the "one-sided" rose scent delivery led to different sleep waves in the two hemispheres. The hemisphere that received the scent revealed better electrical signatures of memory consolidation during sleep. ...
To further evaluate the effects of flurazepam on EEG during sleep, following 7 nights of placebo baseline, flurazepam (30 mg) was administered to 6 young adult poor sleepers for 10 additional nights while 6 other young adult poor sleepers continued to receive placebo capsules in a double-blind...
EEG recordings revealed that their brains continued sorting the words into their proper categories. When participants heard "horse," their brain activity looked as if they were preparing the right hand, not the left, to hit a button. The results may help explain how meaningful sounds, such as...
Previous studies have shown that the clearance of waste material from the brain becomes particularly accelerated during deep sleep. However, the results now obtained reveal that the intensification of pulsation activity already begins during lighter sleep and that deep sleep may not be needed. ...
the sleep stage where we spend the most time. (1) Brain wave activity during N2 sleep includes sleep spindles and K-complexes (or long delta waves). While sleep spindles and K-complexes both play a central role in memory consolidation, K-complexes also play a role in maintaining sleep. (...
Coverage encompasses the network and membrane mechanisms responsible for waking and sleeping brain activity, the roles of glial cells in the sleeping brain, the molecular basis of sleep EEG rhythms, and research on songbirds, rodents, and humans indicating the function of sleep.
