One person "controls" another person's brain through brain waves, which sounds like a plot in science fiction. However, for the first time, American scientists have successfully conducted a human brain "conscious fusion" experiment, making science fiction a reality. Rogersey Rao, a professor of computer science and engineering at the University of Washington in Seattle, USA, conducted a test at the school. Rao sits in the school's lab, and his head is connected to an EEG scanner through electrodes. At this time, on the other side of the campus, Rao’s colleague Andrea Stoke wore a purple swimming cap with a transcranial magnetic stimulation coil, which was just aligned with the left motor cortex that controlled his right hand movement. . Rao looked at the computer screen, imagined that he was manipulating a video game, and fired the gun with his right hand in the game, at which time his hand did not move. The EEG recorded the EEG activity signal of Rao's "fired artillery" and transmitted it to the transcranial magnetic stimulation coil on Stoke's head. Stoke then moved the right index finger and hit the space bar on the front keyboard. . According to Stoke's description, the right hand feels involuntarily, just like nerve twitching. In fact, the concept of "integration of consciousness" in the Rao experiment has appeared for more than 40 years. The research on the name "brain-computer interface" has made many progress. In the concept of "brain machine interface", "brain" refers to the brain or nervous system of organic life forms, and "machine" refers to any processing or computing device, which can be in the form of a simple circuit or a complex silicon chip. Brain-computer interface research refers to the capture of radio signals from the brain, which are then translated into instructions by a computer, so that moving the computer cursor and even manipulating a robotic arm can be completed. Researchers believe that with the deepening of brain-computer interface research, humans can realize that one brain "affects" another brain sooner or later. In February of this year, Miguel Nikolalis, a researcher at the Duke University Medical Center in the United States, used electronic sensors to capture the brain activity signals of a mouse in a laboratory in Brazil and transmitted it to the United States via the Internet. The brain of the little mouse, the result of the American mouse to imitate the action of the Brazilian mouse. Recently, the brain electrical signal of a monkey in the Duke University laboratory was transmitted to Japan via the Internet, and the arm of a robot was manipulated. The goal of most such studies is to help paralyzed patients regain some of their mobility, but bioethicists are also concerned that this "brain control technology" may be used in controversial areas. Some people worry that brain-computer interface technology will be applied to the military field to create "animal soldiers" or "brain-controlled soldiers" whose actions are controlled by people. Reuters said Duke University's brain-computer interface research was funded by the US Department of Defense's Advanced Research Projects Agency, and Rao's trials were funded by the US Army Research Office and other non-military federal agencies. Speaking of his latest experiment, Rao, who has been engaged in brain-computer interface research for more than 10 years, believes that Stoke’s brain reads only simple brain signals, not thoughts. This “integration of consciousness†experiment cannot be unconsciously. The land is used on anyone, let alone the "manipulation" of others. Rao stressed that this research will have great application value in the future. For example, when a pilot on an aircraft loses driving ability, the pilot on the ground can use brain control technology to help others on the plane to land the aircraft. However, brain control technology may be the first to be applied in the field of consumer electronics. With this technology, people can manipulate their smartphones to send emails or adjust the volume by mind. It is reported that South Korea's Samsung is using a head-mounted EEG sensor to test how the brain interacts with the tablet, while other technology companies are also developing similar products.

Freckle, that is, through sunscreen and other ways to remove the spots on the face or body. The formation of spots, mainly internal factors: pressure, endocrine disorders, slow metabolism, the use of the wrong cosmetics, external factors: bad living habits, ultraviolet radiation and other factors caused.
Rapid freckle removal method, although it can play a rapid freckle removal effect, but in the case of destructive treatment results, so we should also pay attention to the repair ability of the skin. Wen changquan introduced that because the epidermal cell layer is damaged in a large area, its self-repair and anti-ultraviolet function is affected, so it may aggravate the disease.
