Neuralink Corporation, Elon Musk’s brain technology company, has reported mechanical issues with the device implanted in its first human patient. Weeks after the January surgery, some electrode-studded threads in the brain tissue began to retract, impairing the device’s proper functioning. Neuralink addressed this issue through software fixes, leading to a significant improvement in the patient’s performance. The company is currently working on enhancing text entry and cursor control for the device, with plans to expand its use to physical devices like robotic arms and wheelchairs.
