According to the British Daily Mail, American scientists recently said that they have successfully developed an instrument that can read human brain thinking. With this instrument, people will have nowhere to hide even the most private ideas
in the latest issue of the public library of science, scientists from Carnegie Mellon University in the United States announced their latest achievement. Researchers at Carnegie Mellon University in the United States said that with the help of scanners and computer programs that took seven years in a Gulf along the coast of Cancun, a resort in southeastern Mexico, they could determine how different regions of the brain activate when thinking about different problems, and found that different people actually think about the same things in the same way. Scientists first used advanced MRI scanners to analyze how the brain responds to pictures of ten tools and buildings; Then, use computer program analysis to study whether someone is thinking about a tool or building. The results showed that the accuracy of the researchers' analysis was as high as 97%, and they also tested the principle of the torsion spring torsion tester and found that the brain could recognize two similar objects, such as two different tools. Brain scans also showed that different brain regions were involved in information processing, such as analyzing simple problems like hammer line drawings
when the brain thinks about how to use a hammer, it activates the brain region responsible for movement, while when the brain thinks about the shape of a hammer, it activates other brain regions. Although it is difficult to pick out the different thoughts after ten paintings, researchers believe that they can quickly determine the whole sentence. In the previous test, the researchers first gave the volunteers a special kind of glasses that can isolate their left and right eyes, and then put a red and a blue colored strip paper in front of the experimenters' left and right eyes at the same time. Participants in the experiment could not see the things in front of their right eyes with their left eyes, nor could they see the things in front of their left eyes with their right eyes. At the same time, the subjects received MRI scans of the brain to observe the EEG response of monocular viewing of color bars. It was found that the subjects' brains would intermittently see blue and red. When the experimenter looks at different colors, the brain will produce different but regular electrokinetic components with a loading range of 25 ⑴, 000 n wave response. Using this principle, scientists finally developed an instrument that allows people to decipher their thoughts
member of the research team, Svetlana shikalawa, said, "we hope to continue to improve to determine the thinking related to pictures, words and even sentences." This new technology will also be applied to human medicine, such as the treatment of autism and other diseases. Marcel gies, the person in charge of the research, people need to study some tiny materials Performance evaluation of small components Professor te said: "People with autism perceive things differently from normal people, and the way they perceive the world is difficult to determine. This machine helps us find and understand their cognitive characteristics. This study has clarified for the first time the fact that different people's brains are the same when thinking about the same problem. However, a philosophical problem is whether one person's perception of color, such as blue, is the same as another. At present, we It has been known that different human brains have a lot in common when dealing with similar things. The research team will also expand the use of the machine, such as using it to conduct reliable lie detection tests. Because it can correctly interpret people's intentions, it can be used to help the police arrest criminals before they commit crimes. "
American scientists said that the successful development of this instrument will have a huge market demand. According to the statistics of the Christopher Reeve Paralysis Foundation, the number of patients with language impairment in the United States is as high as 4million. With the further acceleration of aging in American society, this figure is also showing an increasing trend. Scientists hope that this technology can help more patients with language impairment to communicate freely with others. For example, due to the destruction of the spinal center, patients with spinal cord damage often end up paralyzed. This is because these patients' brain and legs lose the ability to communicate, which directly leads to the loss of control of the patients' legs. Through thinking technology, the brain can directly send command signals to the legs through the chip, thus avoiding the damaged spine. In addition, this technology can also be applied to military fields such as driverless vehicles
