The term "Harrison" in the context of the Neuralink update likely refers to individuals participating in Neuralink's PRIME Study. Neuralink, co-founded by Elon Musk in 2016, is a neurotechnology company developing implantable brain-computer interfaces (BCIs). The PRIME Study is a clinical trial designed to evaluate the safety and functionality of Neuralink's "Link" in individuals with paralysis. The Link is a fully implantable, cosmetically invisible, wireless BCI intended to restore autonomy to people with paralysis, enabling them to operate computers and phones with their thoughts, a capability Neuralink calls "Telepathy".
As of early 2025, there are three known participants with Neuralink implants: Noland, Alex, and Brad. All three have tetraplegia (paralysis in the arms and legs) resulting from either spinal cord injury or amyotrophic lateral sclerosis (ALS). Together, these participants have had their Links implanted for over 670 days and have used Telepathy for over 4,900 hours, including both research sessions and independent use in everyday activities. One participant, Noland, suffered a spinal cord injury prior to the study and now uses the Neuralink to control a computer, browse the internet, play games, and continue his education with greater independence. Neuralink plans to implant devices in 20 to 30 people in 2025 and is planning on expanding their human trials internationally.
