Methods An advantage of sawtooth waves is that the resulting artefact in the EEG recording is significantly simpler to remove than a sine wave as we can clearly see whether a residual artefact remains by the distinctive harmonics which can be seen when the cleaned data is viewed in the ...
An additional advantage of sawtooth waves is that the resulting artifact in the electroencephalogram (EEG) recording is significantly simpler to remove than a sine wave; accordingly we were able to observe alpha oscillations both during and after stimulation. We found that positive ramp sawtooth, but...
Objective: Sawtooth waves (STW) are a characteristic EEG feature of REM sleep but their source and function are unknown. We previously reported stereotypical properties of STW at stage REM onset, and alterations in bulbar postpolio syndrome. This study analyzes STW features throughout REM, in ...
mentalis twitches and sawtooth waves in the EEG were visually scored. REM and twitch densities during REM sleep were significantly higher in the patients than in the controls. The distribution pattern of REMs and twitches was altered in the patients: twitch density peaked in the first REM ...
Objective To describe slow wave activity in the thalamic centro-median nucleus (CMN) region during rapid eye-movement (REM) sleep and its relation to the scalp EEG sawtooth waves. Methods Five (5) patients undergoing stereo-electroencephalography were implanted in the CMN. Sleep was scored using...
