This disclosure relates to devices, methods and systems for the recording of electroencephalograph (EEG) signals and application of subthreshold magnetic stimulation (StMS) to modulate brain activity during sleep. Embodiments of the present disclosure provide devices, methods and systems that acquire an...
Electroencephalography (EEG) is a non-invasive neuroimaging technique that allows researchers to observe dynamic processes in the brain as they happen. It is used to capture electrical activity of the brain during both sleep and wakefulness and allows for the analysis of frequency waves, absolute a...

In wakefulness, the dependence on ongoing oscillatory electroencephalogram (EEG) activity underlying specific cognitive functions has been investigated in particular using tACS and patterned TMS.25 During sleep, a main focus of TMS stimulation to probe brain excitability during sleep TMS has been used ...
The studies presented here underscore the strong dependence on the ongoing brain activity of the induced effects on electroencephalogram (EEG) and behavioral measures. The reviewed data on the effect of applied electric currents on brain electric activity and behavior boost the reemerging concept that ...
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....
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. ...

Indeed, PSG-defined sleep stages were originally devised from EEG as surrogate markers of arousal thresholds, yet over time many have come to see them as a more or less exhaustive set of intrinsic canonical states that cover the full repertoire of brain activity during sleep. However, the use...
