(ORDO NEWS) — Thanks to the device of functional magnetic resonance imaging, you can understand what a person is thinking about.
Neuroscientists at the University of Texas at Austin have learned to track the flow of oxygenated blood through the brain.
It is noted that the corresponding procedure is carried out using functional magnetic resonance imaging (fMRI): active brain cells require more energy and oxygen, so this information provides an indirect measurement of human brain activity.
“This method is not perfect, but thanks to it, scientists can decipher a person’s thoughts. It is not able to reproduce a literal translation, but this is enough to understand what the subject is thinking.”
During the study, scientists scanned the brains of one woman and two men aged 20 to 30 years. They were given to listen to about 16 hours of various podcasts and programs in the scanner.
Then a special “decoder” compared the sound patterns of these programs and the patterns of the recorded brain activity.
According to neuroscientist Alexander Hut, fMRI has “pretty good” reconstructed the original plots of podcasts and broadcasts.
That is, the program was able to draw conclusions about which program the subjects listened to based only on brain activity. The fMRI even managed to reconstruct the stories invented by the participants themselves.
“If any neurologist had been told this 20 years ago, they would have kicked you out with laughter,” Huth said.
Neurologists noted that they plan to use this technology to help people who cannot speak and type on their own.
The idea is certainly a good one, but who guarantees that such or similar technology will not be used against humanity?
