Neuralink Technology
Neuralink is a neurotechnology company developing brain-computer interface (BCI) systems that establish direct communication pathways between the human brain and external devices. The technology uses surgically implanted electrode arrays to record neural signals from the brain, which are then decoded and translated into commands for computers or assistive devices. This approach differs from non-invasive BCI methods by offering higher signal fidelity and more granular control through direct cortical access.
Surgical Procedure and Hardware
The Neuralink implantation procedure involves transdural surgery to position electrode arrays within the brain tissue, typically in motor or sensory cortex regions depending on intended application. The surgical process is facilitated by a robotic system designed to position electrodes with high precision while minimizing tissue damage. The implanted device connects to a neural interface that processes signals and communicates wirelessly with external computers or assistive systems.
Clinical Application Status
As of 2026, Neuralink has progressed from animal testing and feasibility studies to human clinical applications. Early human implant recipients have demonstrated the ability to control computer cursors and external devices through neural signals alone, with documented cases showing functional restoration of communication and control capabilities. These human trials represent the first documented use of the technology in patient care, though long-term efficacy and safety profiles continue to be evaluated through ongoing clinical monitoring.
