Arbaugh's journey to Neuralink began when he learned about the company's clinical trials for brain-computer interfaces. Eager to explore cutting-edge solutions, he applied to participate in the PRIME Study. After careful screening and evaluation, Neuralink selected Arbaugh as their second human trial participant.

In late 2023, Arbaugh underwent surgery to receive the Neuralink implant. The procedure, performed at the Barrow Neurological Institute, was successful. Post-surgery, Arbaugh began the process of learning to control digital devices using only his thoughts, marking a new chapter in his quest for improved quality of life.

Surgical Procedure and Implant Mechanics

Neuralink's brain-computer interface implantation involves precise surgical techniques and specialized hardware components. The procedure integrates advanced technology with neurosurgical expertise to place the device safely in the brain.

Link Device and Electrode Placement

The Link device is a small, disc-shaped implant containing microelectrodes. Surgeons use robotic assistance to achieve high precision during implantation. The procedure begins with a small craniotomy to access the target brain area.

Neurosurgeons then carefully insert the electrodes into specific regions of the brain. These ultra-thin threads contain multiple electrode contacts. The placement is crucial for capturing neural signals effectively.

Real-time imaging guides the surgeons throughout the process. This ensures accurate positioning of the electrodes to maximize signal quality and minimize tissue disruption.

Custom Mount and Brain Chip Integration

A custom titanium mount secures the Link device to the skull. This mount is tailored to each patient's anatomy for optimal fit and stability. It allows the implant to sit flush with the skull surface.

The brain chip, which processes neural signals, is integrated into the Link device. This chip contains advanced microelectronics for signal amplification and processing. It connects wirelessly to external devices, eliminating the need for physical wires exiting the skull.

The integration process involves precise electrical connections between the electrodes and the chip. Engineers calibrate the system to ensure proper functionality. After implantation, the scalp is closed over the device, leaving no external components visible.
