In general, the patient showed uniform metabolism in bilateral frontal lobe (PET-CT), occasional sharp slow waves in the frontal zone (24 h EEG), and no typical SWDs or multiple spike waves during episodic hand tremor (documented with video-EEG monitoring).
Polysomnographic data demonstrates opioids decrease slow wave sleep and REM sleep.
At the beginning of the night, much of the first ninety-minute cycle is filled with slow wave sleep and the first REM episode is usually quite short, maybe five minutes.
The variable and fragmentary nature of deficits in cortical functions and consciousness can be interpreted as being congruent with the also variable local differences in slow wave activity, sleep spindles [68], and gamma bursts [69] during NREM sleep.
The main advantage of the natural or ventilator-supported respiratory wave application [18]-[21] for the CA assessment is the possibility of continuous uninterrupted CA monitoring with up to 10 times shorter monitoring data delay time compared with the slow wave method.
The Biot deformation modulus Q has significant effect on wave propagation in porous media; as seen in Figure 9, reducing the Biot Modulus lowers wave speeds in poroelastic medium (compare to Figure 5) rendering fast p-wave get closer to the elastic wave and transfers energy of the slow wave to the fast wave; further reduction of Q results in the slow wave to disappear in the limit.
So we will here solve and discuss the dispersion relation 5) to study the damping time and damping per period of fast and slow waves.
Among antidepressive drugs, the selective inhibitors of serotonin uptake (SSRI) decrease slow wave sleep and REM sleep and prolong REM sleep latency [19].
Furthermore, the CST Studio Suites [17] were carried out to predict and optimize the performance of the double-ridge loaded FWG slow wave structure (SWS).
But lately researchers have shifted their focus to SWS, or slow wave sleep.
