Neuralink Revolution: Paralyzed Writes with His Mind Thanks to a Chip
The recent announcement from Neuralink , Elon Musk's neurotechnology company, suggests a significant advance in brain-machine interface (BCI) technology. A video released by the company shows a robotic arm writing the word “Convoy” on a whiteboard, apparently controlled by a human patient via an implanted brain chip. This video references the company's “CONVOY” study, which focuses on brain-controlled assistive robotics.
This demonstration highlights the progress of Neuralink's N1 chip, designed to restore mobility and communication for people with disabilities. While specific details remain scarce, the video hints at notable advances in the field of BCI technology.

In November, Neuralink had already announced the approval of a new feasibility study ( CONVOY ) for its brain implant and robotic arm, confirming its commitment to brain-computer interface research.
Brain-controlled robotics: A deeper look
The short 30-second video leaves much to the imagination, including the identity of the subject controlling the arm. Neuralink's post on
The demonstration is part of the CONVOY feasibility study announced in November, which involves participants from the ongoing PRIME (Precise Robotically Implanted Brain-Computer Interface) study.
Neuralink: BCI brain-computer interface
Several observers interpreted the Neuralink demonstration as an example of controlling the robotic arm solely through the patient's thoughts, without the aid of joysticks or muscle sensors. As reported by PCMag, Musk himself confirmed the accuracy of this interpretation.
Neuralink's PRIME project involves implanting a small, cosmetically invisible BCI device into the area of the brain responsible for movement planning. This implant allows individuals with quadriplegia to control external devices such as computers and smartphones using their mind, eliminating the need for wires or physical movement.
Neuralink invited people with disabilities to register, such as those with amyotrophic lateral sclerosis (ALS) or cervical spinal cord injuries that limit or prevent the use of both hands.
In January 2024, Noland Arbaugh , a 30-year-old man paralyzed from the shoulders down following an accident in 2016, became the first human to receive the Neuralink brain implant. Despite some initial difficulties, Neuralink managed to modify the implant's algorithm to improve its sensitivity and restore its functionality.
In August, in a podcast, Musk said that the second BCI patient was achieving good results. Neuralink aims to implant the device in eight more patients by the end of the year and significantly expand its clinical trials. This expansion represents a critical step in validating the effectiveness and safety of the technology on a larger scale.

Expansion of studies and future prospects
Neuralink is expanding its BCI research beyond the United States. After gaining approval for a feasibility study on using its N1 implant to control an assisted robotic arm, the company announced its first international trial.
In November, Neuralink also received approval from Health Canada for the CAN-PRIME study, now open to Canadian citizens.
According to some reports, Canadian neurosurgeons have requested regulatory approval to recruit six patients with paralysis for voluntary BCI device implantation. A specialized 1.8-ton robot will implant 64 electrodes, each with 16 contacts, into the hand motor areas of patients' brains. These electrodes will transmit neural activity, allowing users to control connected devices with just their thoughts.
Meanwhile, further details are awaited on the CONVOY study, which aims to further refine BCI-controlled robotics. Neuralink said it will share further updates in due course as the research progresses.
At this point we can expect ever greater expansions in the brain's ability to control computers or mechanical limbs. The problem still remains the need to implant the sensors intracranially: a simple surgical operation, but which still presents the problems of any implant with an exit from the body towards the outside.
