Surgeries may become safer and more precise than ever before. A new brain implant now lets people control Apple devices, such as iPads, iPhones and the Vision Pro, using only their thoughts. Synchron, an endovascular brain-computer interface (BCI) company based in New York, demonstrated the first wireless BCI that works with Apple's official protocol. Ten patients have received the implant: six in the U.S. and four in Australia. With this technology, users living with severe paralysis can navigate apps, send messages and operate devices hands-free.

Mark Jackson is playing a computer game with his mind. As he reclines in bed, three blue circles appear on a laptop screen a few feet away. One turns red: the target. Jackson is in control of a white circle, which he needs to steer into the target without running into the blue obstacles. The game is a bit like Pac-Man.

Neurotech company Synchron has unveiled the latest version of its brain-computer interface, which uses Nvidia technology and the Apple Vision Pro to enable individuals with paralysis to control digital and physical environments with their thoughts. In a video demonstration at the Nvidia GTC conference this week in San Jose, California, Synchron showed off how its system allows one of its trial participants, Rodney Gorham, who is paralyzed, to control multiple devices in his home. From his sun-filled living room in Melbourne, Australia, Gorham is able to play music from a smart speaker, adjust the lighting, turn on a fan, activate an automatic pet feeder, and run a robotic vacuum. Gorham has lost the use of his voice and much of his body due to having amyotrophic lateral sclerosis, or ALS. The degenerative disease weakens muscles over time and eventually leads to paralysis.

Mark, a 64-year-old with amyotrophic lateral sclerosis, or ALS, uses Amazon Alexa all the time using his voice. But now, thanks to a brain implant, he can also control the virtual assistant with his mind. ALS affects the nerve cells in the brain and spinal cord, causing loss of muscle control over time. Mark, who asked that his last name not be used, has limited mobility as a result of his condition. He can walk and talk but has no use of his arms and hands.

Brain-computer interface technology is at the core of movies such as Ready Player One, The Matrix and Avatar. But outside the realm of science fiction, BCI is being used on Earth to help paralysed people communicate, to study dreams and to control robots. Billionaire entrepreneur Elon Musk announced in January – to much fanfare – that his neurotechnology company Neuralink had implanted a computer chip into a human for the first time. In February, he announced that the patient was able to control a computer mouse with their thoughts. Neuralink's aim is noble: to help people who otherwise can't communicate and interact with the environment.

A year after being cleared for the test, billionaire Elon Musk's Neuralink has implanted its wireless brain chip in a human for the first time. Musk announced that the patient received the implant on Sunday and "is recovering well". The device is meant to have several applications, from restoring motor functionality within people to enabling a brain-computer interface. There was no independent verification of Musk's claims, and Neuralink did not offer too many details. Musk has touted Neuralink as the future of technology and medicine, but ethical concerns have been raised around the chip and its testing.

Elon Musk's Neuralink company, purveyors of the experimental N1 brain-computer interface (BCI), announced on Tuesday that it has finally opened enrollment for its first in-human study, dubbed Precise Robotically Implanted Brain-Computer Interface (PRIME, not PRIBCI). The announcement comes nearly a year after the company's most recent "show and tell" event, four months beyond the timeframe Musk had declared the trials would start, and nearly a month after rival Synchron had already beaten them to market. Per the company's announcement, the PRIME study "aims to evaluate the safety of our implant (N1) and surgical robot (R1) and assess the initial functionality of our BCI for enabling people with paralysis to control external devices with their thoughts." As such, this study is looking primarily for "those who have quadriplegia due to cervical spinal cord injury or amyotrophic lateral sclerosis (ALS)," despite Musk's repeated and unfounded claims that the technology will be useful as vehicle for transhumanistic applications like learning Kung Fu from an SD card, uploading your consciousness to the web and controlling various household electronics with your mind. Actually, that last one is a real goal of both the company and the technology.

"We're not building a BCI to control Spotify or to watch Netflix," the CEO of medical device startup Synchron tersely told Engadget via videocall last week. "There's all this hype and excitement about BCI, about where it might go," Oxley continued. "But the reality is, what's it gonna do for patients? We describe this problem for patients, not around wanting to super-augment their brain or body, but wanting to restore the fundamental agency and autonomy that [able-bodied people] take for granted." Around 31,000 Americans currently live with Amyotrophic lateral sclerosis (ALS) with another 5,000 diagnosed every year. Nearly 300,000 Americans suffer from spinal cord paralysis, and another approximately 18,000 people join those ranks annually.

Dr. Mario did not prepare us for this. In a pioneering effort, researchers from UC San Francisco and UC Berkeley, in partnership with Edinburgh-based Speech Graphics, have devised a groundbreaking communications system that allows a woman, paralyzed by stroke, to speak freely through a digital avatar she controls with a brain-computer interface. Brain-Computer Interfaces (BCIs) are devices that monitor the analog signals produced by your gray matter and convert them into the digital signals that computers understand -- like a mixing soundboard's DAC unit but what fits inside your skull. For this study, researchers led by Dr. Edward Chang, chair of neurological surgery at UCSF, first implanted a 253-pin electrode array into speech center of the patient's brain. Those probes monitored and captured the electrical signals that would have otherwise driven the muscles in her jaw, lips and tongue, and instead, transmitted them through a cabled port in her skull to a bank of processors.

Neuralink Corp., Elon Musk's brain-implant company, said it received approval from the US Food and Drug Administration to conduct human clinical trials. "This is the result of incredible work by the Neuralink team in close collaboration with the FDA and represents an important first step that will one day allow our technology to help many people," the company said Thursday in a tweet. The FDA and Neuralink did not immediately respond to requests for comment. Musk's startup is developing a small device that will link the brain to a computer, consisting of electrode-laced wires. Placing the device requires drilling into the skull. The approval "is really a big deal," said Cristin Welle, a former FDA official and an associate professor of neurosurgery and physiology at the University of Colorado.
