Reason that can go to sleep peacefully under the noisy environment that U.S.A. discovers
Washington, August 9 (Xinhuanet) why some people can go to sleep peacefully under very noisy environment, and other people will wake if have noise slightly? American researcher deliver report, claim reason might lie in the former have completely different spontaneous the intersection of brain and the intersection of rhythm and mode 9.
Researchers have observed a group of experimenters in the laboratory sleep The brain wave modes of 3 nights. First very quiet in night, second because introduce many kinds of sound such as buzz, speak, the intersection of medical equipment and sound,etc. with third night, and seem noisy. Through measuring experimenters' brain wave, researchers find, the brain produces the the more one of sleep spindle wave, keep the possibility of the sleep state the greater while meeting the noise.
Lead researcher of Harvard University medical college Jeffrey and Ellenbogen of this research to say, this because thalamus prevent from feel information reach experience voice and brain area that make a response to sound, sleep the intersection of spindle and unexpected turn of help, stop feeling information reaches the thalamus, " More sleep spindle waves mean more stable sleep, even if on condition that meet the noise " .
This research results Issue in U.S.A. on the 9th >On the magazine . Researchers hope to design through behavioral skill, medicine or method that the device strengthens the sleep spindle wave in the future, improve people's sleep quality.
