Microsleep
Encyclopedia : M : MI : MIC : Microsleep
A microsleep is a period of sleep lasting no more than a few seconds up to a minute. It often occurs as a result of a sleep debt, sleep deprivation, or mental fatigue. Microsleeps (or microsleep episodes) become extremely dangerous when occurring during situations which demand continual alertness, such as driving a motor vehicle or working with a heavy machinery. People who experience microsleeps usually remain unaware of them, instead believing themselves to have been awake the whole time, or feeling a sensation of 'spacing out'.
There is little agreement on how best to identify microsleep episodes. Some experts [[Citing sources citation needed]] define microsleep according to behavioral criteria (head nods, drooping eyelids, etc.), while others [[Citing sources citation needed]] rely on EEG markers, which are known [[Citing sources citation needed]] to be weakly correlated with the behavioral features of sleep.
