This article talks about the how some people who are blind sense objects that are around them by using a technic known as echolocation. Echolocation is basically when a blind person makes clicking noises, which travel away from the mouth until they are deflected by objects back towards the person, to detect things that are around them. In a study, scientists have discovered that these blind people that use this technic use the part of their brain that people with vision use to see. Some people who use echolocation are so good at it that they can actually use it to hike, mountain bike, and even play basketball. They discovered that people use the seeing part of the brain, when they echolocate, by doing a test in which they measured the amount of oxygen consumption different parts of the brain have while performing specific tasks. The more oxygen a part of the brain uses the harder it is working. The last thing that the scientists discovered during the study is that when blind people use echolocation they actually don't really rely on their ears at all.
If seen shows about people who use echolocation to get around on a day to day basis and I find it to be quite amazing. I don't understand how it's even possible to sense what is in front of you by feeling echoes made a clicking sound that you made. The actually quite mind blowing. Anyways, it's also quite interesting how people use the seeing part of their brain while they echolocate. In a way it's kind of like they actually are seeing what's in front of them. I find it hard to believe that some blind people who are really good at echolocation could actually use their skill to go mountain biking and to play basketball. for me that's just a little to unbelievable. I mean I can barely play basketball with 20/20 vision.
