One possible reason may be that, in preeclampsia, intermittent hypoxia associated with dysrhythmic breathing and resultant cardiopulmonary desynchronisation
results in sympathetic activation, significantly diminishing vagal balance .
There is also a relationship between sleep disorders and cancer-related fatigue (18), probably by desynchronisation
of the circadian rhythm (19).

following hand motor imagery," Clinical Neurophysiology, vol.
Due to the presence of both MI's event-related desynchronisation
(ERD) feature and SSVEP's prominent peak at the flicker frequency, the hybrid BCI is expected to show better performance in comparison with a single mode BCI.
We base our analysis on the physical model of Kuramoto , that provides a system that can model synchronisation and desynchronisation
in groups of coupled oscillators.
Zangemeister and Stark observed an offset (or desynchronisation
) of 2 movements .
Figure 5 presents sample ERD (event-related desynchronisation
) recorded during motor imagery of both left and right hand.
Similarly, another study showed that the detection of visual stimuli near the perceptual threshold was more reliable during episodes of alpha desynchronisation
than during episodes of alpha synchronisation .
* Improved the desynchronisation
detection in Multiplayer Campaign mode, and players are now given a popup message when a desynchronisation
has occurred, with the options to resynchronise the game to continue, or quit the game.
All cyclists experienced increased sleep latencies compared to baseline levels, consistent with the effects of a desynchronisation
between endogenous circadian rhythm and sleep-wake cycles (Liu et al., 2000).
Using a rat model of the disease, the team's recordings showed desynchronisation
of the waves of activity, which normally travel from the front to the back of the brain during deep sleep.
