I want you guys to watch two movie scenes. In both you will see how the cable is connected to the human brain. The first is from a film that almost everyone knows: from the 1999 Matrix.
Seems like a pretty painful experience. The second scene I'm going to show now shows us a more painless experience as it was shot in July 2019 at a much recent date. Multiple thin cables are connected to the brain instead of one thick cable. Yeah, you wonder what movie I got this second scene from? Actually, I didn't take this scene from a movie, but a presentation. We’ve seen real footage of a robot developed by Neuralink. This robot, which works like a sewing machine, is sewing cables. One end of those cables will be connected to the human brain and the other end to a computer. So a brain-computer-connection will be made: BCC. Sounds like a joke. Or you might think this could only be in sci-fi movies. But I said I took this scene from a presentation. The presenter is Elon Musk. After the rockets to go to Mars and self-propelled electric cars, he couldn’t keep himself from studying the human brain. Neuralink, a company that developed the technology I just showed, was secretly (let’s not say secretly , but silently) founded in 2016 by him and his friends. Because the public learned this only in March 2017. By then they had hired some of the world's most famous neuroscientists from various universities. As a result of the 3-years work of 90 people, it was announced to the world with a presentation made last July 16th.
Technically, they work on a “brain-computer interface. What does that mean? Let's first understand how our brains work. Those who were following my channel will remember, I made a four episode summer school series last year and talked about our brain and how it learned. I compared the brain's inner structure to the roots of trees. Trees represent our brain cells, neurons. We can say that we have a forest consisting of one hundred billion trees in our mindd and they communicate by touching each other’s roots. The two brain cells make a synapse connection and send chemical signals to each other. That's when a small electric field forms around it. If you put a thin cable - an electrode - in this area, you can capture those signals. So you can record the information produced by the brain cell. What if we can not only record it but use it? For example, can we use a computer with our brains?
