U.S.A. : The scientist unravels and spends holidays the mystery difficult to relax
A lot of people expect to spend festivals or holidays or spend holidays to relieve working pressure, the relaxed body and mind well. However, no matter how beautiful the seabeach is, how pleasant the scenery is, millions of holiday makers seem unable to relax oneself. Discover newly, as to some people, it is unable on vacation to be two weeks -long " L Forget the work and settle down to spend holidays " .
According to September 22 of medias of foreign countries, U.S.A.>A new research that is published newly has been opened tentatively " L Difficult to spend holidays to relax " R Its mystery. This new research is stored Denira, mathematician of university by the west of market Keys of Cleveland of Ohio state of U.S.A. Do base of a fruit doctor and his colleague cooperation finish Karl's linking . The scientist finds, it is rare for a lot of people to get away to have a holiday from the busy job, but always keep thinking about the E-mail, reply message and office affairs etc. for the colleague in the heart. Even in spending holidays, it is difficult to be relaxed to always feel body and mind, the unable stop of the state of mind.
Discover newly, not merely " L Ponder over the question " R Will consume energy, " L Prevent oneself from pondering over some questions " R Will consume energy too. Researchers say, in the course for holidays " L Clear up the thinking, make great efforts not to think of anything " R Method, like" L The downhill path parks " ,Even you are unwilling, the car will glide automatically. The latest result of study still shows, " L It is difficult to ponder with all worries set aside " R And " L Always feel in the brain that there is a song that is being broadcast repeatedly, can not get rid of " R Also the same reason.
In order to open " L Think " R Or " L Stop thinking deeply " R The secret of consumed energy, researchers have designed one can imitate the brain " L Energy is turned into the thought " R Computer model. This software has been duplicated and connected " L The excitatory neuron " (transmit the brain cell of the thought) Sum " L The inhibiting neuron " (brain cell preventing the thought from transmitting) Passway .
Karl link the intersection of base of a fruit and Dr. say want, prevent a certain thought, brain will utilize person who inhibit from neuron prevent the excitative brain cell from transmit message each other. The inhibiting from neuron will send out " L Don't do so! " R Order,its way is pass last material butanoic acid (GABA)s amino s chemical ,Offset the function of another kind of chemical material glutaminic acid in the brain. Open the passway between the brain neuron with glutaminic acid, but GABA closes the passway between the brain neuron.
New the intersection of research and cooperator gram strange to ask for silent Sa Lip river Dr., say computer model experimental result reveal strategic point have, keep glutaminic acid and GABA finishing the totally opposite one " The work " ,The brain must consume more oxygen. The greater oxygen consumption is, need greater blood flow volume and more energy. " L Stop thinking deeply " R It is big and amazing to consume energy, this is exactly " L Difficult to spend holidays to relax " R The very crux. Researchers say, will also launch the excitatory neuron to imitate and compare with the experiment simultaneously with inhibiting from neuron next.
Researchers say, though what this research used is an icy computer model, but its goal is to help people to solve " L Difficult to spend holidays to relax " R ,etc. difficult problem. Usually difficult to diagnose to or damage because of brain disease, once it is often already in a difficult condition for saving to find. So, researchers think, the computer model will contribute to analysing and explaining the difficult problem of of brain of senile dementia,etc..
