Neuralink chip is a brain-machine interface to connect humans and computers. It is a brain implant that makes it possible for the brain to wirelessly interface with a machine. It’s kind of like a Fitbit in your skull, with tiny wires,. The physical device that Musk presented to the audience looks about the same size as a R2 coin. Attached to it are threads that house electrical conductors that can be implanted into the brain. To insert it, a piece of the skull is cut out and replaced with a coin-size device figure 1.<br /><br />The threads on the Link are so fine and flexible that they can’t be inserted by the human hand. To insert one of these, they are developing a robot that the neurosurgeon can use to reliably and efficiently insert these threads exactly where they need to be. Musk said that eventually the whole process would be automated. “The Link procedure, the installation of the Link… done in under an hour. So you can basically go in the morning and leave the hospital in the afternoon.<br />The device would also come with a charger, circular in shape, that can be plugged into a power source to wirelessly charge the Neuralink from outside the human body. The device would then allow users to control a digital device such as a smartphone with their minds. The Neuralink app would allow you to control your device and mouse directly with the activity of your brain, just by thinking about it. <br />While this sci-fi future might be appealing to some in the general populace, Musk told the audience that Neuralink’s goal is to create a device that can solve important spine and brain problems with a seamlessly implanted device. Neuralink’s website also states that the “initial goal” of their “technology will be to help people with paralysis to regain independence through the control of devices. Devices are designed to give people the ability to communicate more easily via text or speech synthesis to express their creativity through photography, or writing applications.<br />A second-generation implant that's more compact and fits into a small cavity hollowed out of the skull. Tiny electrode "threads" penetrate the outer surface of the brain, detecting an electrical impulse from nerve cells that shows the brain is at work. In line with Neuralink's longer-term plans, the threads are designed to communicate back, with computer-generated signals of their own figure 2. It communicates with brain cells with 1,024 thin electrodes that penetrate the outer layer of the brain. Then there's a Bluetooth link to an outside computing device, though the company is looking at other radio technology it can use to dramatically increase the number of data links.<br /><br />Neuralink allows monkey to play video games.He’s not uncomfortable, and he doesn’t look weird. And you can’t even see where the neural implant went in, says Musk. He added that video game playing monkey was able to control the electronic interface completely using its mind.
