A brain computer into face is a way of getting electronics to talk directly to those brain cells, recording the electrical signals in the brain. And it effectively allows our brains to communicate with technology without the need for our sensory systems or our motor systems. i would imagine that implanting a device into the brain with all its different regions and its unending complexity, must be a really difficult thing to do. Yes. So there's different ways to interface with the brain. Some people use electrodes on the surface of the skull to try and pick up the electrical signals from the brain. But the closer you can get to the brain cells themselves, the better you can listen to the electrical signals they're sending
