Do we really use the 10% of our brain? Does this mean that the other cells that form the brain are useless? First we need to know how we got this idea. We probably heard it because of an experiment done by Karl Lashley. He explored the brain using electroshock, and noticed that many areas of the brain did not react to the shock, so he concluded that these areas had no function at all.
Today is well known that the brain has specific functional primary areas like the visual, somatic sensitive and auditory ones. And some regions are linked to attention and language. Physiologists usually describe and explain separately these areas, giving the impression that the brain works area by area. Well, that’s false. Neuroscience now shows that we use 100% of our brain.
Not all the people know that we have secondary areas surrounding the primary ones that receive a part of their information. For example, when we see an object, the image perceived by the eyes is sent to primary visual area and then to the secondary one. But not only the visual area gets active, it also does the region linked to the memory and language to recognize the object and name it.
I used to believe the myth but after reading this I don’t. It’s shocking to know how complex the brain is and that all of the information we get from the environment is complex too and we need to associate sound with images and smells to understand what’s happening outside. And that implies the use of many areas of our brain, another more than the others but still. It's amezing how the brain can get all the information and makes us understand the things that happens outside! Am I the only one thinking that the brain it’s perfectly done?
