Control of sleep courses in the brain ... a new role for "Blue Zone"

Researchers from the Swiss University of Luzan have succeeded in determining a new and unexpected role for the ‘Locus Coerleus’ in the brain, as the study published in the magazine “Nature Neurusins” said that this region plays a major role in organizing the sleep cycle and the transition between the non -rapids of the movement of the movement Eye movement. The study also showed that stress negatively affects the functions of this region and leads to sleep quality disorder. The blue region in the brain is a small area in the brain stem, and it is the most important center for the production of light adrenaline, a hormone and neurotransmitter that plays an important role in various physiological and behavioral functions, and it is part of the nervous system responsible for the body’s response to pressure or tension, which is sometimes exposed to the to the threat or the body function, which is submitted, which is exposed vigilance and concentration in preparation for interaction with emergency situations. Organizing sleep courses. Sleep in mammals consists of alternating courses between the non -rapid sleep and the rapid type of eye movement, as deep sleep plays an important role in restoring the activity of the body, while the sleep of rapid eye movement is related to dreams and intense cerebral activity, but the rules that regulate these courses are still unclear. The new study reveals that the blue region of the brain stem is a key to regulate the transition between these cases. Although this region is known for its role in the response of the brain to challenges during vigilance, the study has shown that it works as a ‘watch’ regulator who determines the timing of the transition between the stages of sleep, as changes in activity lead to direct effects on the regulation of sleep cycles. The activity of that region during sleep is characterized by regular fluctuations that occur every 50 seconds during these attacks of activity, the activity of the region rises, leading to the secretion of larger amounts of light adrenaline in the brain. This discharge stimulates some parts of the brain to become almost vigilant, allowing the body to respond to the external environment without making a complete awakening, and when the activity decreases, the body can move to the fast sleeping stage, enabling balanced and comfortable sleep cycles. In the non -rapid sleep phase of the movement of the eye, physical recovery and the balance of different body functions occur, which increases the general ease of the body, but in the phase of rapid eye movement, memory and regulation of feelings is improved, which is an important matter for spiritual and psychological health. The blue region plays an important role in organizing these operations because it works as a guard to control transfers between these two cases of sleep, contributing to a balanced and healthy sleep. Tension impedes the study. The study showed that exposure to tension during the day increases the activity of the blue region during sleep, which impedes the transition to deep sleep and makes the sleep of the quick eye more spread, and this results in a large number of partial awakening and the continuity of sleep, and this effect appears in both cortical and cortical parts of the brain. The study also reveals that the ‘Blue Zone’ may have played a role in structuring sleep during the development of living organisms. While mammals show clear sleeping, some reptiles have similar patterns that change during close periods, which are indicative of the presence of old evolutionary roots of this work. The researchers note that the ‘blue zone’ can be used as a reliable important indicator of monitoring sleep cycles and diagnosing associated disorders. Its results can also be used to pave the way to develop techniques that help correct these courses more accurately and effectively, contributing to achieving a healthy balance between the different stages of sleep. The research teams are currently working to implement these promising results in human studies in collaboration with University of Lausanne Hospital; It aims to determine the extent to which the nerve activity in the blue region is linked to the sleeping patterns in humans, and the extent of the possibility of taking advantage of these mechanisms to effectively improve the quality of sleep for individuals with sleep problems.
