  Microsleep - Wikipedia, the free encyclopedia
A microsleep is a period of sleep lasting no more than a few seconds up to a minute.
Microsleep becomes extremely dangerous when it occurs during situations when continual alertness is demanded, such as driving a motor vehicle.
Some experts define microsleep according to behavioral criteria (head nods, drooping eyelids, etc.), while others rely on EEG markers, which are known to be weakly correlated with the behavioral features of sleep.

 Microsleep | Microsleeps
Microsleeps are brief, unintended episodes of loss of attention associated with events such as blank stare, head snapping, and prolonged eye closure which may occur when a person is fatigued but trying to stay awake to perform a monotonous task like driving a car or watching a computer screen.
Microsleep episodes last from a few seconds to several minutes, and often the person is not aware that a microsleep has occurred.
During a microsleep, a pilot might not be aware of flashing alarm lights in the cockpit.

In one study of microsleep, participants were asked to press a button when a strobe light was flashed directly in their eyes every few seconds.
During a microsleep they did not notice the light and were not even aware that they had been asleep.

According to a study of the umbrella organisation of the German insurance business (GdV), microsleep is the cause of 24% of fatal motorway accidents.
Here the typical approach of the BMW Group is not to wait with the warning until the driver is already drowsy, but to warn him before this, when his alertness is only slightly diminished.
Looking at these factors alone, the topicality of the subject of road accidents caused by microsleep is clear and shows the need for the development of a system that helps protect drivers from such accidents.

A microsleep is a brief period of sleep which can range from just a few seconds to several minutes. Falling into a microsleep for even just a few seconds while driving greatly increases the likelihood of a having a serious crash, especially when travelling at high speed on rural roads.
The Microsleep campaign aims to inform drivers and passengers of the increased crash risk associated with  fatigue and the importance of stopping regularly to rest, especially on long trips.

A train guard's microsleep and a culture that discouraged the use of the emergency brake had stopped a guard trying to slow a train which derailed, killing seven people, an inquiry was told yesterday.
The commission of inquiry into the derailment at Waterfall on January 31 heard that a microsleep lasting up to 30 seconds may have prevented the guard from "pulling the tail" and slowing the train from 117 kmh.
He rejected the suggestion that Mr Van Kessel suffered a microsleep as an explanation for the train not being slowed.

 Sleep
While in theory a sound concept, the major problem with microsleeping is that it takes a very large number of 100 msec increments to put together a significant total amount of sleep.
Another drawback is that, on a tandem, unless both captain and stoker can synchronize their microsleep intervals, one part of the team is always going to act surprised when the bike suddenly starts to careen from side-to-side or heads directly towards the nearest ditch.
While not as efficient as microsleeping (since your velocity vector is "0" while you’re napping), power-napping is considered a safer method.

The term "microsleeps" is often used to refer to episodes lasting up to 30 seconds during which people behaviorally demonstrate a decreased awareness of environmental stimuli and excessive sleepiness.
While the transient nature of microsleeps can make identification of their occurrence difficult, visual inspection of our EEG records suggested that some of the subjects seemed to be experiencing this phenomenon.
Although the records failed to meet the criteria for scoring as stage 1 sleep, a noticable slowing of the central EEG wave occurred from a relatively low voltage, fast frequency pattern (eyes open) to low voltage, mixed frequency activity in the 3-7 Hz range that lasted for several seconds.

This hypnagogic phenomenon is sometimes referred to as microsleep, in which less than 15 seconds of low-voltage mixed-frequency EEG intrudes into a majority pattern of alpha and/or beta activity defining a nominal epoch of wakefulness.
In this particular record, the periods of microsleep, hypopneas, EEG arousals, and oxygen desaturations began to occur at epoch number 58 long before (69.5 minutes before) even the first epoch of recorded sleep (which occurred on epoch number 197).
In the case of this particular patient, the transition from wakefulness to drowsiness to sleep was repeatedly impeded by a sleep apnea or a sleep hypopnea, which was almost always followed by an EEG arousal long enough to cause the 30-second epoch to be scored as wakefulness (rather than sleep).

PURPOSE: The qualitative presence of microsleep during the Multiple Sleep Latency Test (MSLT) has been shown to correlate with an increased incidence of subjective complaints of sleepiness tiredness, accidents/near accidents, and gap driving.
However there is no data as to how to quantify microsleep and effectively incorporate it as a diagnostic tool in me measurement of sleepiness.
The purpose of this study is to integrate microsleep to the MSLT score and determine if it improves the correlation between the MSLT and symptomatic sleepiness.
