American scientists have developed a new brain implant
Researchers at the University of California have unveiled a new brain implant that can help "talk".
The principle of operation of the device is to synchronize the brain and vocal cords. Scientists have come up with an alternative to hovering the cursor over a computer screen and using this to select certain letters, numbers or words. The main goal of the new development is to track brain activity. And in particular, we are talking about the areas of control of voice systems.
This technology allows paralyzed people to literally "move" their lips and pronounce individual sounds, which are subsequently transformed into words. The brain sends signals to the larynx, lips, and jaw.
As part of a new study, scientists described the first human test. He suffered a stroke more than 10 years ago and communicate with others only with the help of a manipulator attached to his chest. Through the sensor, words are printed on the screen.
The electrodes of the new device were placed over the speech cortex in the brain. And then for several months the activity was monitored, which corrected the signals with a fixed vocabulary. Also, neural networks responsible for recognition entered the course.
The man answered simple closed-ended questions about the desire to drink water or eat.
Scientists believe that the next stage of testing will attract more applicants.
Implants, as well as all kinds of functional sensors, can be found in the section "Medical equipment and health products".
