What happens when a person does not sleep at all?

If a person does not sleep within 48 hours straight, s/he has tendency of becoming psychotic. Sleep deprivation can adversely affect brain function.A 2000 study by the UCSD School of Medicine and the Veterans Affairs Healthcare System in San Diego, used functional magnetic resonance imaging (fMRI) technology to monitor activity in the brains of sleep-deprived subjects performing simple verbal learning tasks. The study showed that regions of the brain's prefrontal cortex (PFC) displayed more activity in sleepier subjects. Depending on the task at hand, in some cases the brain attempts to compensate for the adverse effects caused by lack of sleep. The temporal lobe, which is a brain region involved in language processing, was activated during verbal learning in rested subjects but not in sleep deprived subjects. The parietal lobe, not activated in rested subjects during the verbal exercise, was more active when the subjects were deprived of sleep. Although memory performance was less efficient with sleep deprivation, greater activity in the parietal region was associated with better memory. The British television reality show Shattered aired in 2004, in which contestants had to endure seven days with very little sleep. The effects of sleep deprivation on the brain were captured on 24/7 cameras.

I believe that he disturbs of the sleep are frequent and common: persons of all the ages often accuse not to sleep for nothing, not to rest well or not to succeed to take sleep. Immediate and visible they are the effects of one deficiency of sleep: ags under the eyes, anxiety, irritability, nervousness and fatigue.
