Matthew Walker, an assistant professor at the University of California said that sleep is not just for your health, but it is very important for the brain. In the study, Walker and 39 young adults were divided into two groups. At noon, all the participants took part in the exercise of memory to remember faces and link them with names.
Then the researchers took part in memory training in the afternoon after sleeping for 20-100 minutes. "Those who stay awake doing tests by 10 percent worse than take a nap," said Walker. One other thing that is obtained from the study, a person's ability to learn between noon and six o'clock decreased by 10 percent, but this decline negates nap.
Studies show that the phase structure dreamless sleep improves memory. "Sleep plays an important role in memory processing. And give a lot of evidence that sleep is not only important for after learning, but you need it before learning to prepare the brain to put the information."
Long sleep gives the brain a chance to remember during the sleep cycle. After performing an electroencephalogram tests to track electrical activity in the brain, the researchers set, memory refresher occur between deep sleep and dream, which is called rapid eye movement (REM).
"The brain's ability to absorb information is not always stable," said Walker. "It seems that the capacity of the brain may be a bit like a sponge that will get soaked if you continue to learn throughout the day."
Jessica Payne, an assistant professor at the University of Notre Dame, said the results provide additional evidence of the importance of sleep. Sleep is very important for students and those who fight to preserve the memory due to aging. Other recent research proves sleep can help you think more creatively, maintaining long-term memory better and preserve important memories.
