Sleeping is one of the most important activities for the brain in a day. Recent studies have shown that when we fall into a deep sleep, our brain will start to do logistic work to clean up the debris of all-day work and help us reset the neural network, ensuring that it can run efficiently again when we wake up again. But lack of sleep would deprive the important rest part of brain, leading us to a tired condition during the daytime.
According to the report in US Times on April 5th, a group of researchers from China and Europe carried out a detailed analysis on insomnia, the study of how insomnia affects brain cognitive, perceptual and emotional part.
Brain imaging study compared the results of 23 normal sleep insomnia staff and personnel. Researchers focused on the brain's white matter volume. White matter volume can reflect what is called myelin specific proteins on nerve cells attached, which can improve the ability of nerve cells to transmit signals between cells. Early brain imaging studies show that differences in a specific part of the brain people insomnia may be due to a lack of myelin due.
The researchers found that compared with normal people, people with insomnia (refers to more than one month's time sleep problems, daytime sleepiness and sleep disorders people) show significantly less link of white matter, particularly in the area of controlling sleep and wakefulness. Presumably, the signal interference between these regions resulted from the reduce of myelin around neurons, thereby the degree of activity and association between them reduced.
Scientists have found that in fact, insomnia people would lose 83% (that is 5/6) of the nerve diameter, most of which are located on the right side of the brain, that is the area which controls emotion, thinking function and perceptive functions like sense of light, smell and touch. In the future, more research is needed to explain what might cause the differences of brains among people with insomnia.
