Neuralink, Elon Musk’s neurotechnology startup that is developing interfaces to connect human minds to computers, held a big event yesterday to announce what progress they had made over the last one year. For the uninitiated, Neuralink aims to help people with severe neurological disabilities via devices that can be implanted in the brain. Neurons, which are the basic working units of the nervous system, transmit signals to other parts of the body. All of that information exchange happens over minuscule electrical signals. With the Neuralink device in place, patients should be able to regain or improve upon the effects of neurological injuries. Since every action in the human mind and body works over the same electrical impulse principle, theoretically, it can be used to achieve a lot more things. All of our senses are basically signals sent by the brain, and are thus, alterable. Using external readers to record neural activities is not a new concept. It is currently being used for...
