Neuralink implanted a second brain chip in a patient.

In a podcast lasting over eight hours, released late on August 2nd, Elon Musk stated that this patient suffered a spinal cord injury similar to that of the first patient, who was paralyzed in a diving accident.

The billionaire who owns the company added that the 400 implanted electrodes in the second patient's brain are functioning. On its website, Neuralink claims that its implant uses 1,024 electrodes.

"It looks like everything is going extremely well with the second implant. There are lots of signals, lots of electrodes. Everything is working very well," Musk told podcast host Lex Fridman.

Neuralink is in the process of testing a brain chip device designed to help people with spinal cord injuries. The device has already allowed the first patients to play video games, browse the internet, post on social media, and move the cursor on a laptop.

Musk did not disclose when Neuralink would perform the second surgery on a patient. He expressed hope that Neuralink would provide the implant to eight more patients this year as part of a clinical trial.

The first patient, Noland Arbaugh, was also interviewed on the podcast along with three Neuralink executives, who provided details on how the robotic implant and surgery work.

Before Arbaugh received the implant in January, he had to use a computer with a stick in his mouth to touch the device's screen. With the implanted chip, Arbaugh now simply thinks about what he wants to happen on the computer screen, and the device makes it happen. He says the device has given him a little more independence and reduced his reliance on caregivers.

Initially, Arbaugh encountered problems when the small wires in the implant contracted, leading to a sharp reduction in the electrodes used to measure brain signals. Neuralink learned about this issue from animal trials and restored Arbaugh's ability to measure brain signals by making changes, including modifying the algorithm for greater sensitivity.
