Discover physiological characteristic of the brain is to influence the first reason of sleep quality


Is sound of snoring thunderous in why some people can be in the thunder and lightning weather? Do some people hear any sound unable to fall asleep? According to August 10 of medias of foreign countries, the newest finding, the secret of good sleep lies in the spindle wave that the brain produces " Rhyth >
This is issued on >The thesis of the magazine is called, U.S.A. rough state in the outstanding Buddha of general hospital and the intersection of root and Dr. and counterpart of Harvard University, uncle of Ellen, study person in the sleep influenced by any factors to the sensitive intensity of the noise . As a result, they find this kind of sensitivity is in most close relation with spindle wave of the bn>
The wave of the spindle is produced from the thalamus of the brain, and the thalamus is responsible for a kind of structure transmitting the signal of the external world to the other parts of brain. Researchers think, the thalamus produces the wave of the spindle just in order to prevent the brain in the external noise disturbance sleep in view of the ae>
For the one that verify the spindle wave " L Quiet to make an uproar" R Function, researcher produce situation, measure to 12 healthy the intersection of volunteer and the intersection of spindle and wave in the sleep at first. In the following experiment, researchers have assessed them and resisted the road surface noise and ability of the telephone ringer sound in the sleep. The experimental result reveals, the higher one's spindle wave rhythm is, it is the more difficult to be woken.>
The centre expert says at night in Sweden Stockholm university: " Previous research verifies, the wave of the spindle can inhibit stimulating the interference on sleep outsidely effectively, so this result of study accords with logic very much. In addition, perhaps the wave of the spindle can be regarded as a physiological index of weighing sleep quali >
Certainly, spindle wave help, sleep function assumption of researcher, it whether direct interfering noise remain, prove further even to the transmission of the brain. In the experiment, the volunteer's spindle wave rhythm basically maitains unchanged, it means it is a person " L The speciality " . Root of Ellen uncle Dr. say as for why some people have fast rhythm, others have slow rhythm, the reason is still still indeterminate .
