London, February 4 (Xinhua) ' The reporter is yellow) Britain and Belgian researcher are by way of detecting the change of brain wave, succeed in falling into man for many years of vegetable's state and going on with one " Exchange " ,This patient can " Answer " The simple one " " With " deny " Question. This research means in implementing problems such as euthanasia,etc. to the vegetable, it is necessary for people to consider respecting patient's opinion. Medical cognition and researcher and Belgium of the scientific research institute of brain of research committee of Britain go together and report this on " medical magazine of New England " published on the 3rd Research results. Generally speaking, the vegetable damages because of the brain, it is usually unable to speak or pass the limb " language " Exchange with external world, but researchers infer some vegetables may still maintain brain thinking. Then, the researchers of Britain and Belgium try to utilize technology of magnetic resonance imaging of the function to detect the change of brain wave, have exchanged with a vegetable. This patient, for men, 29 years old, he became the vegetable after a traffic accident of experience in 2003. Researchers try to ask him some simple problems affirmed and denied. Because " " With " deny " The brain wave caused is more similar, researchers tell patient that if wants to answer " yes " ,Imagine playing tennis, this will cause the upper brain wave change of brain; If want to answer " Deny " ,Imagine strolling about at home, this brain wave change that will cause the brain to be bottom. Researchers have asked this patient 6 simple problems, the name of his father substantially as providing is correct, he has sisters,etc., the patients all answered correctly finally. Cognition and scientific doctor, Ou Wen of research institute, of brain participating in studying say, when seeing brain wave scans the result to reveal vegetables can answer the question correctly, researchers are all shocked. This means the patient can understand the order, understands the question and makes the decision. Study yet to reveal, about 10% of the vegetables may have ability to control the brain wave, that is to say they can exchange with external world through the brain wave. This research means in implementing problems such as euthanasia,etc. to the vegetable, it is necessary for people to consider respecting patient's opinion. But the expert thinks, can make the simple one " yes " With " deny " Answer, can't yet explain vegetable, have intact thinking and solve complicated ability of problem.
