Neuralink’s first human brain chip trial shows promising results


Neuralink, the neurotechnology company founded by Elon Musk, has successfully implanted a brain chip in a human patient for the first time, according to a tweet by Musk on Monday. The patient, whose identity has not been revealed, is recovering well after the procedure and has shown promising neuron spike detection, Musk said.

What is Neuralink and what does it aim to do?

Neuralink is a startup that aims to develop a wireless brain-computer interface (BCI) that can enable people with severe paralysis to control external devices with their thoughts. The BCI consists of a small device called Telepathy that is implanted in the skull and connected to ultra-fine threads that record and stimulate neural activity in the brain.

Neuralink’s vision is to create a future where humans can seamlessly interact with technology and enhance their cognitive abilities. The company hopes to eventually enable people to communicate faster than speech, access information directly from the internet, and even merge their minds with artificial intelligence.

How did Neuralink conduct its first human trial?

Neuralink received clearance from the U.S. Food and Drug Administration (FDA) in May 2023 to conduct its first human trial, called the Prime study, to test the safety and functionality of its implant and surgical robot. The study will enroll up to 10 patients with quadriplegia, or paralysis of all four limbs, who have lost the ability to perform activities of daily living.

The first patient underwent the implantation procedure on Sunday, January 28, 2024, at a hospital in California. The procedure involved using a robot developed by Neuralink to insert the Telepathy device and the threads into the patient’s brain through small holes in the skull. The surgery lasted for about two hours and was performed under general anesthesia.

The patient is now recovering in the hospital and will be monitored for any adverse events or complications. Neuralink will also assess the functionality of the implant by recording the patient’s neural signals and testing their ability to control a computer cursor or a smartphone app with their thoughts.

What are the challenges and opportunities for Neuralink?

Neuralink’s first human trial is a significant milestone for the field of neurotechnology, as it represents one of the most advanced and invasive attempts to create a direct link between the human brain and a machine. However, the company still faces many challenges and uncertainties before it can achieve its ambitious goals.

Some of the challenges include ensuring the safety and biocompatibility of the implant, preventing infection and inflammation, minimizing tissue damage and scarring, optimizing the signal quality and bandwidth, developing user-friendly and intuitive software, and addressing ethical and social implications.

On the other hand, Neuralink also has many opportunities to make a positive impact on the world. The company’s technology could potentially help millions of people with neurological disorders, such as ALS, Parkinson’s, stroke, spinal cord injury, and blindness, to restore their function and quality of life. Neuralink could also open new possibilities for scientific research, education, entertainment, and human enhancement.

Neuralink is not the only company working on BCI technology. Several other startups, such as Synchron, Precision Neuroscience, Paradromics, and Blackrock Neurotech, have also developed similar systems and conducted human trials. However, Neuralink has the advantage of being backed by Musk, who is also the CEO of Tesla and SpaceX, and has a track record of disrupting and innovating various industries.

Neuralink’s first human trial is just the beginning of a long and exciting journey. The company plans to conduct more trials and studies in the future, and eventually launch its product to the public. Neuralink’s ultimate goal is to create a symbiosis between humans and machines, and to unlock the full potential of the human mind.
