The group of scientists manages to read the mind with great accuracy, but it has a trick

When a person loses speech ability, A Brain interfaces capable of Read the mind They become a great need. Until now, there were many options based on the detection of neuronal signals associated with the movement of the lips to speak. That is, users think about something to say, try and, even if they don’t get it, neuronal signals that the trigger can be interpreted by the machine. Thanks to this type of interfaces, it has recently been achieved that a patient with Ela can communicate with his loved ones. However, there are quite important inconveniences: The process is tiring for users.

To avoid this problem, a team of scientists from Stanford University He developed an interface of the brain machine, which can completely read the mind. That is, he does not reveal the intention to speak, but interprets this Internal monologue What we often have when we mean anything.

With the first tests, the mind of a group of volunteers was read with an accuracy of 74 %. And best, the car begins with password. It would be very inconvenient for his thoughts to identify at any time. If they really want to disable them, just think about the password to start the entire mechanism. Without a doubt, the future should continue in this line. Many patients will benefit from this.

How can a car read the mind with such accuracy?

Both of the speech and the internal share of speech in the origin in Motor cortex brain. However, when analyzing the activity of the brain in patients using each of them, scientists of Stanford University saw that there is also a neuronal motor measurement of motor intention, which allows you to differentiate one from the other. Basically, when there is an intention Neuronal activity of more intensiveThe field is weaker activity only with speech. This would allow patients to think about what they mean, without any intention of movement.

To develop your brainstorm interface, they have developed The algorithm of artificial intelligence And they taught him with the brain activity of a group of volunteers who think Previously selected words and phrasesThis lesson was discovered thanks to some The electrodes are implanted into the bark of the engine.

In total, it was possible to introduce into the algorithm until 125,000 words. Then, when the volunteers again thought about new phrases, the algorithm was able to determine its content with an accuracy of 74 %. And the best thing that was determined not only the words that they had previously asked to think. Also a few more spontaneous ones.

The mechanism activated by the password

Imagine that you use an interface devoted to reading your mind continuously and violate the content of your thoughts. Any failure can be a catastrophe of the most popular episode Black mirrorTherefore, these scientists entered the field in the process. Only when users think about the phrase Chitty Chitty Bang Reading thoughts is activated. When this keyword was checked, the mechanism worked with Accuracy 98 %.

Who will be useful?

Although these types of devices that can read the mind make us think about Futuristic society Where all of humanity is cyborgs, the reality is such that, at least at the moment, the goal is to use it in patients than They cannot speak from health problems, Like people with Ela or cerebral paralysis.

Without a doubt, the return of the ability to communicate can be a breath of fresh air for them. Sometimes artificial intelligence can be conceived as something dark, but it shows us that it can also shed a lot of light.
