"Yet no legal or medical standards exist for identifying overtired drivers on the road the same way we target drunk drivers. "Inadequate sleep exerts a similar influence on our brain as drinking too much," Fried said. The researchers compared the effects of sleep deprivation to those of drunk driving. Stage 3 of NREM sleep is the deepest sleep of the sleep cycle.

For example, when a sleep-deprived driver sees a pedestrian stepping in front of his car, it may take longer for the driver to realize what he or she is seeing because "the very act of seeing the pedestrian slows down in the driver's overtired brain," Nir said. Most adults spend up to 20 of their night in deep sleep. REM sleep usually makes up about 25 of total sleep time for adults. If you’re sleeping 7 to 9 hours per night (as recommended for a healthy adult), you need 60 to 120 minutes of REM sleep during that time. In addition, the findings suggest that a lack of sleep can interfere with the ability of neurons in the brain to encode information and translate visual input into conscious thought, the researchers said. The amount of REM sleep you need depends on your age and the total time spent sleeping. "This phenomenon suggests that select regions of the patients' brains were dozing, causing mental lapses, while the rest of the brain was awake and running as usual," Fried said. Regions of the brain that experienced sluggish brain cell activity also exhibited brain activity normally seen when a person is asleep, the researchers said. In addition, the researchers found that sleep deprivation affects some areas of the brain more than others. "Unlike the usual rapid reaction, the neurons responded slowly, fired more weakly and their transmissions dragged on longer than usual." "We were fascinated to observe how sleep deprivation dampened brain cell activity," lead study author Yuval Nir, a sleep researcher at Tel Aviv University in Israel, said in the statement. The researchers found that as the patients got tired, it became more challenging for them to categorize the images, and their brain cells began to slow down.
Specifically, the researchers focused on cell activity in the temporal lobe, which regulates visual perception and memory.
Each image caused cells in areas of the brain to produce distinctive patterns of electrical activity. For example, the patients were asked to categorize various imagesof faces, places and animalsas fast as possible. Sometimes REM sleep problems can be due to underlying medical conditions, such as sleep apnea, Lyme disease, restless leg syndrome or pain disorders (12). During this time, the researchers measured the participants' brain activity as they carried out certain tasks. The people in the study then had to stay up for an entire night.
