The American technology company Neuralink has received U.S. government approval to test its brain implant device in humans. The approval came from the Food and Drug Administration (FDA). Neuralink says the FDA’s approval will permit the company to expand its current testing program involving animals. Neuralink is owned by American billionaire Elon Musk. He also owns several other companies, including Tesla, SpaceX and Twitter. The coin-sized device is designed to be placed inside the skull. Small wires connect it directly to the brain. The implant contains a small computer that is built to communicate with the brain. This lets it control operations in the body. Neuralink has said the technology is designed to treat brain disorders and help spinal cord injury victims regain body movement. It might also be able to help blind people see again.
