Eeg machine and automation of transcranial magnetic stimulation technology such as telepathy is not just a dream
Satellite Internet, virtual reality, artificial intelligence, are cool technology, right?But rather than social networking site facebook founder, mark zuckerberg to the idea of the future communication, they seem to be "too weak".
Zuckerberg said this week with the online quiz, people communicate in the future may be without the communication medium, but "good for the brain induction" directly.
A, on the basis of brain waves
Read the idea
Let's look at the brain's principle of work: in short, the human nervous system is composed of neurons, neurons with chemicals called neurotransmitters transmit signals to each other.Neurons to accept signal, brain waves produce peak.Brain every next instruction, such as reading an article, remember one thing, such as neurons need millions of signals, so keep moving brain waves.
Using existing electroencephalography (eeg), nuclear magnetic resonance (NMR) technology, scientists have been able to measure and map the activity of brain waves.Electroencephalogram (eeg) if you get enough, scientists may be able to read out the idea of the brain.
In one experiment, the university of California, Berkeley cognitive scientists have successfully according to the subjects of brainwave activity, reducing them to watch video clips.
Theoretical physicist beauty ZhiXiong Angle of wang rong said after watching the video clips of these scientists reduction, these fragments although details is not clear, but "to be able to clearly identify the subject".
B) using the stimulation technology
Transmit the signals other people
How will your brain signals into someone else's brain?Duke university in 2013, an experiment method is to try and implants in the brain.
Researchers in two microelectrodes implanted mice brains, training one press a root in two poles.In the rat brain neural signals through the microelectrode is passed to another weasel, prompting the latter push the same poles.
Different from the "invasive" approach, researchers at harvard medical school in 2014 using transcranial magnetic stimulation technology, realized the experiment object distance "induction".
The experiment, a experimental object in India "up" two words, the "idea" is recorded on electroencephalogram (eeg), in the form of binary code by email sent to France, by transcranial magnetic stimulation technology three passed to the recipient's brain.The receiver wore a device converts binary code into the human brain can recognize the electromagnetic signal, in the form of phosphene to the receiver.
Within one of the researchers pascual, Leon, said: "we are trying to determine, whether by reading one brain activity and achieved through the brain into another two people communicate directly... with the help of wireless electroencephalogram (eeg) and transcranial magnetic stimulation, such as advanced automation precision neural technology, we did it directly as a noninvasive and convey one's thoughts to another person, without they said or wrote."
C in the primary stage
Facing many questions
Pascual DE Leon said that in "explore complement or bypass based on language or feasibility of muscle movement, the traditional communication way", the above experiment "represents an important first step".
However, complexity, and in terms of accuracy, speed, and application cost, etc, the experimental implementation of the "induction" is still in the "primary stage".As the MIT technology review article puts it: "' should be the feeling of 'technology is still the primary, could not have a real impact."Further development to promote the "induction" technology, researchers are doing more to try.For example, the study on someone is holding a nuclear magnetic resonance (NMR) equipment, size, such as mobile phone, to reduce the difficulty of the capture of brain activity and cost;American troops are developing "induction helmet."
"Face book" has so far not released any associated "induction" technology research.For social networking sites, research and development and using the "induction" technology may also face the user privacy, security, ethics, and many other aspects of the question.The Washington post, citing a study published in 2014, about the academic papers of "good for the brain and technology ethics" warning, for such research, the legislature and academia hasn't any formal rules.
