Five years ago, 24-year-old Ian Burkhardt was paralyzed below the chest due to an accident. Today he can pick up his coffee cup, swipe his credit card, and even play the guitar. These are all realized by ideas. He is the first person to implant a brain chip. The chip controls muscle movement by decoding neural information signals.
This milestone was published in a scientific journal, bringing hope to patients with paralysis such as strokes around the world.
Berkhardt and his friend were injured in the neck when playing in the sea, which allowed him to sit in a wheelchair and not be able to move his elbow. Bathing, dressing, brushing, and other normal things are simple things that depend on others. He only completed the first year of college.
Fortunately, his brain can also generate ideas for exercise. But his spinal cord is damaged and he can't send instructions to her muscles. To give the brain instructions, doctors at the Ohio State University Hospital implanted the microchip into the brain, bypassing the damaged spinal cord.
Now that Burkhardt wants to control the movement of the hand, the chip "listens" to the brain cell's information and sends the signal to the computer for decoding. The computer then sends the information to the sleeve that is nested on the right arm of Berkhardt. Once activated, the electrodes will stimulate the muscles and allow him to move.
Burkhardt said: "When I first picked up something with my hand, I was very shocked because I couldn't control my hand for three and a half years. Now my hand is very flexible, just like I did before the accident. â€
Different brain signals activate different muscles, allowing Mr. Burkhardt to complete the process of swiping a credit card, stirring a spoon and picking up a glass. Surprisingly, he can even control his fingers precisely and play computer games that play guitar.
In the future, he will be able to finish clothes, dress, and even type.
The technology is still in its infancy and can only be used in the laboratory. But the R&D team is diminishing it and expecting it to be used in the home in the next few years. At the same time, the computer will be replaced by a mobile phone, and the wired connection will be replaced by wireless technology.
