In the future, she will be able to help people with speech impairments, researchers hope
The technology to decipher human thoughts and turn them into words was developed by a team of experts led by Robert Knight of the University of Berkeley. By analyzing the activity of the brain, the device created by specialists will be able to eavesdrop on the "voice in the head" of a person and compose a text based on the relevant information.
For a long time, experts have studied how different parts of the brain react when a person hears a particular word, says it aloud or thinks about it. The data obtained were used to create a computer program whose task is to "translate" certain brain signals into words.
The device that was created at this stage is capable of reproducing with a high degree of accuracy a word that a person has recently heard by analyzing various signals in the temporal lobe of the brain using electrodes. In the future, as scientists hope, their development will be able to turn detailed human thoughts into coherent sentences, writes the Daily Mail.
Experts note that they still have a lot of work to do before it becomes possible to apply the technology in practice, but in the future it can help people who have lost the ability to speak for some reason to fully convey their thoughts to others. Scientists hope that one day, based on their developments, a device with an electronic speaker will be created, accessible to many people and suitable for constant use.
By the way, recently another group of scientists representing the University of California at Berkeley was able to confirm that, although the regions "in general" responsible for speech and language are located in the temporal lobe of the left hemisphere, almost the entire brain is involved in the recognition of certain words. human. Moreover, the researchers managed to create a kind of "map" on which you can see in which parts of the brain the pronunciation of a particular word causes activity.
