Neurophysiology of sleep-wake states in relation to consciousness
... A key structure in the regulation of sleeping and waking and thus of consciousness is the reticular formation, a meshwork of nuclei and tracts located in the brainstem (e.g. Steriade and McCarley, 1990). The brainstem reticular formation roughly consists of two systems. The first is located in the r ...

Effects of sleep deprivation on cognitive performance
It has been estimated that over 20% of adults suffer from some form of sleep deprivation. Insomnia and sleep deprivation are common symptoms of depression and can be an indication of other mental disorders. The consequences of not getting enough sleep could have dire results; not only to the health of the individual, but those around them as sleep deprivation increases the risk of human-error related accidents, especially with vigilance-based tasks involving technology.
