Implantation of the chip in the brain of the second patient was approved by Elon Musk
Startup Neuralink has implanted its second chip in a patient's brain to help paralyzed people use digital devices with the power to think.
According to Isna, citing Guardian, “Elon Musk” (Elon Musk), the owner of the startup “Neuralink” announced in a podcast that this startup has successfully implanted its chip in the brain of the second patient to enable the use of digital devices with To provide thinking for patients with limb paralysis.
Neuralink is testing its chip, which is intended to help people with spinal cord injuries. The device helped the first patient play video games, search the Internet, post on social media, and move the cursor on his laptop.
In his statement, Musk provided few details about the second participant, saying only that he suffered from the same spinal cord injury as the first patient, who was paralyzed in a diving accident. According to Musk, 400 electrodes are working on the second patient's brain. Neuralink has written on its website that the chip uses 1024 electrodes.
“It looks like the second chip is going very well,” Musk said. There are many signals and electrodes that work very well.
Musk did not disclose when the second patient's surgery would be performed, and said he expects Neuralink to implant the next chips in the brains of eight more patients this year as part of its clinical trials.
“Noland Arbaugh” (Noland Arbaugh), the first patient to receive the chip, was also present in this podcast along with three Neuralink managers. They provided details on how the chip works and the robot-guided surgery.
Before Arbaugh received the chip, he used a stick in his mouth to tap the tablet's screen. With the chip, Arbaugh said, he can now think about what he wants to appear on the computer screen and have the device do it. He noted that the chip has given him some independence and reduced his reliance on caregivers.
Arbaugh initially experienced problems after the surgery because the chip's tiny wires became tangled and the electrodes that could measure brain signals became less efficient. Reuters reported that Neuralink was aware of this in its animal experiments.
Neuralink said it restored the chip's ability to monitor Arbug's brain signals by making changes that included tweaking the chip's algorithm to be more sensitive. Musk said in the podcast that Arbaugh has bettered his previous world record for speeding up cursor control by thinking alone.
