We are on the verge of being able to realize the well known phrase "I think therefore I am". In other words, we can will our thought and transforming them to action such as typing out an piece of prose describing the though without any physical actions on our partt. We are gradually learning how to transmit our thoughts as electrical impulses that a computer can understand and proceeds to carry out the actions desired by the brain (very much in the same way our brain can order our muscles to move our hands and limbs).This technology while still primitive carries the title of this article https://www.google.com/search?client=avast-a-1&q=brain+computer+interface+technology&oq=Brain+Computer+Interface&aqs=avast.2.69i57j0l7.17396j0j15&ie=UTF-8 . It is just part of understanding the functioning of our brain - the least nderstood part of our body. When adequately developed, the technology will be of great help to the physically handicapped as well as many advance applications currently not even unvisioned..

Here is a personal experience about medical treatment of our brain that is impossible years ago. during a routine scan of my wife's brain last year, the doctors discovered a relatively large aneurysm in one of the major blood vessel in her brain. This is very serious since if the aneurysm breaks, serious brain damage and death can result., since olperating on the brain to repair the blood vessel is not feasble, the doctors fashioned several small platinum balls made by bundle of thin platinum wires. These balls are introduced into the blood circulatory system and carefully manuvered into the blood vessels in the brain and eventually into the aneurysm to plug it up. To me this sounded like science fiction. But this is apparently routinely done nowadays. When one is reasonably healthy and not working in biology and medicine, one is often surprised by advances in medical technology.
