Human cognition is complex and limitless. This was reported by Zamin.uz.
Until now, the idea of reading human thoughts — previously found only in science fiction — is now being tested in real research. Scientists at Stanford University have, for the first time, succeeded in detecting a person's inner speech, that is, thoughts directed inward without vocalization, using special technology.
Information about this was published in an article in the journal Cell. The study employed a new method based on an interface between the brain and computer.
This technology analyzes neural activity signals and converts them into text form. It was found that the system can identify a person's intentions and inner speech with 74 percent accuracy.
The experiment involved four patients with severe paralysis. Microelectrode implants were placed in the brain area controlling speech activity.
As a result, the device was able to convert the words the patients wanted to say, or even phrases formed only in their minds, into text with high accuracy. Scientists emphasized that it is also possible to detect sequences of numbers generated in the human mind during simple computational processes.
Security aspects of the device were also considered. To ensure privacy, it can only be activated through a special “smart password.”
This method was noted to operate with over 98 percent accuracy. According to experts, this technology is not yet fully ready for practical application.
However, in the future, it may open new opportunities for people with limited speech ability or those deprived of communication due to severe illness. Scientists aim to continue work in this direction and further improve the system.
Thus, science has once again enabled the study of the deepest layers of the human mind. Today, ideas resembling science fiction may well begin a completely new era of communication tomorrow.
