Clinical Trials
PRIME Study Neuralink's first-in-human clinical trial is called PRIME (Precise Robotically Implanted Brain-Computer Interface):
Identifier : NCT05126784Status : RecruitingTarget : Patients with quadriplegia due to spinal cord injury or ALSPrimary Endpoint : Safety and device functionalityFirst Human Implant (2025) In January 2025, Neuralink announced successful implantation of the N1 device in their first human patient:
Patient demonstrated ability to control computer cursor using neural signals
Successfully played chess and interacted with software
Demonstrated high-accuracy motor intent decoding (>90%)
No serious adverse events reported in initial cohort[@neuralink2025]
Second Patient Neuralink has implanted devices in additional patients as part of the PRIME study, expanding clinical experience with the technology.
Applications
Initial Target Indications
Quadriplegia : Enable patients with spinal cord injuries to control computers and devicesALS : Restore communication abilities for patients with late-stage ALSBlindness : Blindsight program for visual cortex stimulation
Future Applications
Human-AI Symbiosis : Musk's stated long-term goal is to enable humans to interface with AIMemory Augmentation : Potential for cognitive enhancement in Alzheimer's diseaseTreatment of Neurological Conditions : Depression, addiction, PTSD (speculative)Competitive Landscape Neuralink competes with other BCI companies:
| Company | Technology | Status |
