Some of the electrodes became detached from the patient’s brain after the operation. The implant from Elon Musk’s company is supposed to make it possible to operate the smartphone with your mind.
Elon Musk’s brain implant company Neuralink has struggled with a problem with its first patient. In the weeks following the operation in January, some of the electrodes became detached from the man’s brain, Neuralink admitted in a blog entry on Wednesday. However, this was compensated for by adapting the software. Neuralink only made the problem public after the Wall Street Journal found out about it and asked the company.
Neuralink’s implant is intended to make it possible to use your thoughts to operate a smartphone – and other technology. The company received permission in May 2023 to use the flat and round implant on people in a clinical study. The technology had previously been tested on monkeys. The implant has 1,024 electrodes that a robot connects to the brain using an extremely fine needle. For the clinical trial, Neuralink looked for patients with quadriplegia – a paraplegia that affects the legs and arms.
Algorithm made more sensitive to problems
When people start to move, a certain area of the brain becomes active. The electrodes collect these signals. It should be enough to imagine a movement in order to operate a cursor on the computer. According to the company, the first patient with the Neuralink implant can, among other things, surf the Internet and play chess and the video game “Mario Kart”.
Because of the detached electrodes, the precision and speed of cursor operation initially decreased, Neuralink stated. In response, the algorithm for detecting brain activity has been made more sensitive and the technology that translates it into cursor movements has been improved. After the software adjustment, the accuracy values were higher than before, the blog entry said.
Neuralink did not provide any information about the reasons for the electrodes being removed. According to the Wall Street Journal, one of the theories at the company was that air may have remained in the skull after the operation. The study is being overseen by the US Food and Drug Administration (FDA).
