Studies say lack of sleep inhibits brain activity and creates cognitive gaps.

According to British media, the latest study shows that even when people are awake, there will actually be part of the brain resting, this study will have a significant impact on fatigue driving.
A brain scan of sleep-deprived people by scientists at the University of California, Los Angeles (UCLA) showed for the first time that fatigue disrupts the speed at which brain cells communicate and prevents memory from being coded properly, and can also cause temporary loss of memory and vision, the Daily Telegraph reported on November 6.
, a professor of neurosurgery at UCLA, says this can leave tired people unable to notice pedestrians walking in front of cars. "Lack of sleep also deprives nerve cells of the ability to function properly, which can lead to cognitive gaps when we perceive and react to the world around us," he said. Seeing pedestrians slow down in the driver's tired brain takes longer to remember what he perceives.
said: "The effects of lack of sleep on our brains are similar to those of being drunk, but there are no legal or medical standards to identify fatigued driving as much as to identify drunk driving."
the scientists involved in the study studied 12 people with sleep-deprived epilepsy who had their brains connected to electrodes and asked to classify a series of images as quickly as possible. As patients become more sleepy, the more difficult it is for them to accomplish this task. Scans showed that as patients completed tasks, so did their brain cells.
, lead author of the study and a professor at Tel Aviv University, added: "We were shocked to find out how lack of sleep inhibits brain cell activity. Unlike the usual rapid response, nerve cells react much faster and transmit much more slowly than normal. The
also found that brain waves also slowed in areas where cells were stimulated more slowly, suggesting that the region was trying to rest.
Said:
This phenomenon suggests that certain areas of the patient's brain are dull and cause memory loss, while the rest of the brain is awake and functions properly.
previous studies linked sleep deprivation to an increased risk of depression, obesity, diabetes, heart disease and stroke, and medical errors, the study was published in the British journal Nature Communications.
