"Link," includes ultra-thin threads that are surgically placed in the brain to monitor neural activity and potentially stimulate it. These devices are intended for applications in medical treatment, such as helping individuals with paralysis regain motor function or communication capabilities. Neuralink also invests in developing robotic surgical systems to perform the implantation procedure with high accuracy and minimal invasiveness. The long-term goal involves enabling broader human-computer symbiosis, including interaction with artificial intelligence systems.
