Second Human To Receive Neuralink Brain Chip Uses It To Play Counter-Strike 2

In a blog post on Wednesday, Neuralink said its second human recipient is using the brain chip to play Counter-Strike 2 and develop 3D designs in CAD software. 'Alex' was given the brain chip last month to help restore his autonomy after a spinal cord injury. PCMag reports: Like the first Neuralink patient, Noland Arbaugh, Alex has also been using the brain chip to play his favorite computer games, such as Counter-Strike 2. Before, Alex had to use a mouth-operated controller, called a QuadStick, to play the first-person shooter. But even then, the controller limited him to only moving or aiming his weapon at a single time, never simultaneously like a normal Counter-Strike player. In other words, Alex had to essentially switch back and forth between the mouse and keyboard functions while playing the game. But thanks to Neuralink, he can now aim with the implant, and simultaneously move while using the QuadStick.

In the blog post, Neuralink also addressed a problem the company faced when placing the chip in Arbaugh, the first patient. Despite a successful surgery, about 85% of the thread-based electrodes attached to his brain later became displaced, undermining the full potential of the chip to read neural signals. Although Arbaugh can still use his implant effectively, Neuralink wanted to avoid a repeat with Alex. In response, the company developed several 'mitigations,' which include reducing the chance of an air pocket forming during surgery and placing the implant deeper into the brain tissue. 'Promisingly, we have observed no thread retraction in our second participant,' the company said of Alex.

Whether Alex's implant outperforms the brain chip in Arbaugh was left unclear. In the meantime, Neuralink says it's working on ways to enhance the controls on the technology 'to deliver full mouse and video game controller functionality.' 'Additionally, we plan to enable the Link [brain chip] to interact with the physical world, allowing users to feed themselves and move more independently by controlling a robotic arm or their wheelchair,' the company said. You can watch Alex playing Counter-Strike 2 on YouTube.
