Benefits Of Sleep For The Brain
Interestingly, most of the “new,” twenty-first-century discoveries regarding sleep were delightfully summarized in 1611 in Macbeth, act two, scene two(most)where Shakespeare prophetically states that sleep is “the chief nourisher in life’s feast.”
SLEEP FOR THE BRAIN
Brain’s numerous functions depend upon sleep. No one type of sleep accomplishes all. Sleep is not the absence of wakefulness instead it is far more than that. Sleep is the order set of a unique stage like Light NREM, deep NREM and REM. Each type of sleep offer different brain benefits at different times of night. Sleep helps our to function properly as well as refreshes our ability to acquire more information. Lack of sleep distort our brain functionality and losing out of any stage may cause brain impairment.
Sleep before learning offers the brain to make new memories and acquire fact-based knowledge. When you wake up in the morning you brain is refresh and ready to acquire information. As we all know that student face difficulty in late night study compare to in the early morning. Our brain has a specific region called hippocampus which is long, the finger-shaped structure tucked deep on either side of your brain. It offers short-term memory which in modern day analogy like camera roll capacity or USB capacity. Fact-based information or textbook learning type information are stored in the hippocampus. Sleep offers a great deal of help for memorizing.
As we know that the hippocampus has limited capacity. Exceed it sizes causes to forgetting information. Overwriting one memory with another cause a mishap called interference forgetting. We wonder how the sleep helps the brain to restore past information. In order to know our research team perform daytime naps observe it. We take a group of young healthy adults and divide them randomly, one group who was a nap gap group and second group no-nap group. All the participants underwent a rigorous session. The nap group took the ninety-minute nap in daytime with electrodes places on their heads while non- nap group were awake doing some menial activities like browsing internet, playing games etc.
Both group were learned some new interesting facts to tax their hippocampus their short-term storage before going for lab experiment. later that day, the nap-group underwent a ninety minute of sleep and no-nap group perform were doing others activities. At six p.m. we tested both groups and we found that the nap group perform well while no-nap group perform worse (we found it using intense learning). The difference was not small, 20 percent of learning advantage for those who slept. During sleep the brain transfer all the information in the hippocampus using some kind of file transfers mechanism to long-term memory hold i.e. cortex. Cortex serves as a long term memory.
