Are you ever thought that someone can read your mind when you think about? Unless the conspiracy theorists, I am afraid that very few people would think. After the kindergarten age people understand telepathy is not true. And did "Nature" magazine published a paper researchers at Duke University, a mice brain waves they will pass through the Internet the other mice in the brain, so that the latter can be done without any visual image the case completed the visual test.
This is how to do? When humans to read other people's thoughts? To answer these questions, we must first be able to understand the structure of this experiment, and the experiment proves anything. This experiment using rats, their brain's primary motor cortex (primary motor cortex) were implanted microelectrodes. They are also trained by pressing the lever, it is possible the two levers in one of the above light-emitting diode (LED) lights up when pressing the corresponding lever. If the action is correct, it can open a device containing sugar, rewarded. By analyzing the neural activity in mice when the lever is pressed, the researchers found that the pattern of neural activity when the lever is pressed on the left when you press the right side of the lever and not the same, the difference of whether pressing the correct lever irrelevant.
These mice were divided into "coding" and "decoding persons", which are placed in exactly the same shape of the cage after cage has pressed a lever to get a reward. In the "coder" in the environment, there will be LED lights, it should be noted that the lever is pressed, while Cage "by decoding" is located in the no signal (LED lights). The researchers found that after the "coders" to complete the visual test, their brain waves transmitted through the Internet, can help mice received brain wave rewarded in their cages, even if the latter is no visual cues (LED lights). The team found that, although the "decoding by" no visual cues, they press the correct leverage the success rate can still reach 60% to 72%. If the communication and movement between the two mice are correct, they will be rewarded encouragement, which greatly increases their success rate and with the degree.
In a second experiment, the rats were trained to use their whiskers to explore a cave, then turn left or right to indicate the entrance is narrow or wide. One pair of mice still being put together as before, but this electrode is implanted in the primary sensorimotor cortex (primary somatosensory cortex), this region deal with the sense of touch. Although only a "coder" Exploring the hole, but the "decoded by" pointed in the right hole width ratio can exceed 60%.
Finally, the "coder" is placed in a stationary state, while using their whiskers touch the metal bar. The researchers observed that, "decoder persons" primary sensory cortex and also appeared in "coders" similar patterns of activity, even if the "decoding persons" beard has not been touched.
Professor Miguel Nikolay Nice led the research, said: "These findings confirm the first time, in addition to conventional animal communication, it is possible to establish a direct channel for the exchange of information between two acts of the animals' brains."
Etc ...... There may be another one just to see mice mice are doing, so its behavior and has nothing to do whether to establish a connection via the Internet? Do not worry, in fact, two mice in a North Carolina lab, and the other in Brazil. The only disadvantage of this setting, the distance leads to a slight signal propagation delay. "The most interesting, the researchers found that in mice two pair soon after the establishment of understanding, which may be based on some form of sensory feedback. If the second only mice could not complete the task, the first only mice modifies its transmission signal, second only to help mice. two mice unity, because they are faced with sufficient reward incentive. "
To admit that these experiments are simple, as are dual decide their concerns, even though mice can guess by a 50% success rate. However, the University of Pittsburgh who neurobiology Andrew Schwartz, research progress in the field of brain-computer interface has been far beyond the above experiments. Schwartz lab have the monkey's brain linked with the computer, so that "a rhesus monkey can use mind control arm movement in three research results have been applied to human beings, a quadriplegic woman able to use the mind to control the robotic arm to feed their own chocolate. "
These experiments show that we have been able to establish a precise, direct communication channels of communication between brain and machine ...... So, in essence, "We are creating what I call 'organic computer' things," Miguel Nikolay Nice professor said, "If an animal becomes 'brain network' part, we can not even predict what will be its interactive features. in theory, you can imagine, a lot of the brain can be joined together to provide a single brain can not be given solutions. "these results are not only attractive, but also for some people is terrible. Some people are afraid of these results improper use do not know what are the consequences. They are not wrong. If this technology fall into the hands of the military may cause enormous damage, especially if a non-invasive way to achieve this technology words. Its use may be that a human operator using a brain wave remote control insects, mammals or robots. However, in the short term, this technology can be used in a very positive purposes, such as war-wounded veterans or people with disabilities can regain limb and control limb new ways to be close to the natural limb.
"In a pinch, so efficient communication can save lives", a biomedical engineer at the University of Warwick Christopher James pointed out, because the alarm system can go beyond the senses ...... "I can see that I can taste, I can speak, I can hear, but I have this straight through to my brain perceived ability. "However, the research progress in this direction will take a very long time to be able to convey abstract thinking, or handle more complex tasks . "Even if you could invent non-invasive techniques and in this way the human brain are connected to the transmission of abstract thinking it is impossible, because even a very simple task, such as to imagine a rabbit, but also need a lot of brain part of the common and to reproduce the rabbit in another person's brain, about the need to have a detailed map of human brain (and in this respect everyone is different), but also at different times in a particular way to stimulate the brain a plurality of regions, and so on, and so on.
Professor James said: "The human brain (compared to processors) is a great advantage is that it has tremendous parallel processing capability, and each brain region is a large-scale interconnected." Nikolay Nice and James believes that someday may be able to do that, but not now.
Looking to the future, "such as 50 years, if they can simultaneously stimulate multiple sites, and you know what should be done when stimulation patterns, may be able to induce complex 'thinking'," Professor James said, "more abstract thinking Interpretation is difficult, more difficult to express, but not technically impossible. we can already do that ...... we just need a better understanding of the brain. "
"In the distant future, we may be able to 'brain network' exchange," said Nikolay Nice. "If my great-grandchildren can spend this brain network, and this technology stems from my work, I would be very happy. As to whether we have a 'brain network' prospects feel peace of mind, it will be you (the reader) and the whole society to decide. "
