According to the British Daily Mail, at present, Canadian scientists have recently developed a computer system for reading brains, which helps to establish communication with patients with coma.
Researchers at the University of Western Ontario in Canada use neuroimaging to read brain thinking through brain activity, causing some comatose patients to answer “yes†or “noâ€. The research team said the study is the latest method of establishing communication with comatose patients in the vegetative state. The study, published in the recently published journal Neuroscience, titled "Brain Silence Courier: Using Selective Attention to Decode Brain Thinking to Communicate Between Brains."
Lorina Naci, a postdoctoral researcher at the Institute of Brain and Mind at the University of Western Ontario, said that the interpretation of human thinking through brain activity is one of the most cutting-edge and challenging researches in modern neuroscience. . Especially those patients with completely awake brain consciousness, because of brain tissue damage, they can not express any behavioral characteristics, expose the limited nature of the neuromuscular system, and the need to establish communication. In this study, participants were asked some simple questions, just answer yes or no, for example: Are you married? Do you have brothers and sisters?
Naxi said: "By studying brain activity, we can correctly decode the correct answer for everyone." Most testers can express their answers in only 3 minutes of scanning. This time window is very suitable for brain-computer interface. Exchange communication.
Currently, Naxi and colleagues use this method to establish communication with non-responsive behavior patients, who may be patients who are mistakenly judged to be vegetative.
