Neurolink, Musk’s brain computer interface company, held a launch event to disclose the practical neuralink devices and automatic implant surgical devices.
Elon Musk used a pig named Gertrude to demonstrate the latest technology of his start-up neuralink, which creates a digital link between the brain and the computer, known as the “brain computer interface.”. Wireless connections on the neuralink device show the pig’s brain activity as it sniffs around a pen on stage on Friday night.
Neuralink’s demonstration shows that brain computer interface technology is closer to fulfilling Musk’s ambition than it was when the product debuted in 2019. In 2019, neuralink only shows a picture, in which neuralink connects a teacher’s neuron through usb-c port, which is far away from realizing brain computer interface. But musk said the US Food and Drug Administration approved testing of “breakthrough devices” in July.
Musk also showed a second-generation device that was more sophisticated and could fit into a small cavity dug out of a hole in the skull.
“It’s like a Fitbit in your skull with lots of little wires,” Musk said of the device The device can communicate with brain cells through 1024 thin electrodes that penetrate brain cells. In addition, there is a Bluetooth connection to an external computing device. But the company is working on other radio technologies, hoping to significantly increase the number of data connections.
Neuralink’s medical purpose
Neuralink’s first focus on medical treatment, such as helping people deal with brain and spinal cord injuries or birth defects. This technology can help paraplegic patients who have lost their ability to move or feel due to spinal cord injury. The first application of neuralink in human body will be to improve the living conditions of those suffering from paraplegia or quadriplegia.
“If you can feel what people want to do with their limbs, you can do a second implant where the spine is injured and create a neural shunt,” Musk said. In the long run, I’m confident of resuming one’s full body activity. ”
But in fact, Musk’s views are much more radical, including “voluntary telepathy” in which two people can communicate digitally by thinking about each other rather than by writing or speaking. Neuralink’s long-term goal is to create a “digital super intelligence layer” that connects humans with artificial intelligence. In Musk’s view, artificial intelligence is a threat to human survival.
The most extreme future
“The future will be strange,” Musk said of neuralink’s sci-fi uses. In the future, you will be able to save and restore memories. You can basically take your memory as a backup and then restore it. You can download them to a new body or to a robot body. ”
Musk said he was well aware that some people would point out the problems with neuralink. “It sounds more and more like an episode of the dystopian TV series black mirror,” Musk said
Neuralink is developing a robotic installation program that will eventually be designed to handle the entire surgical installation process. This includes opening the scalp, removing part of the skull, inserting hundreds of “threaded” electrodes, 6 mm deep, with the attached chip, and then suturing the incision. Musk said the device was designed to avoid blood vessels to avoid bleeding.
Like Fitbit, apple watch and other wearable technologies, musk believes that in addition to direct brain computer communication, neural links can bring health benefits. Musk said the chip could measure temperature, pressure and movement, which could alert users before a heart attack or stroke.
Previous work of neuralink
Since its launch last year, musk and neuralink have published a scientific paper in the October issue of the Journal of medical Internet research. This paper describes the development of their robotic device, a robotic arm that can finely insert hundreds of thin wires (about a tenth of human hair) into the brain. Sometimes called a “sewing machine,” it can insert six threads per minute, each made of flexible plastic and equipped with 192 electrodes.
Neuralink’s early work focused on connecting to the brains of rodents. In their October paper, musk and neuralink describe in detail two neural network systems a and B tested in rats. The former can insert more than 1500 electrodes, and the latter can insert more than 3000 electrodes. This paper describes a free-moving rat connected to system B with a usb-c slot on its head, but there is no clear indication that neuralink has determined the best location for the electrodes.
In the paper, musk and neuralink acknowledge that “significant technical challenges have to be addressed before high bandwidth devices are suitable for clinical use.”
Rodent research is impressive, but last year, musk asserted that monkeys “can control computers with their brains.”. The paper published in JMIR does not provide evidence to support this assertion, and musk did not mention it on Friday.
