If we can make good use of the mind has not been part of the development, we can become wiser, more innovative, everyone would like to see the matter. Unfortunately, Claudia Hammond brought us bad news.
How much medical research hypothesis can give our picks, the number is really amazing. However, certain parts of the body seems to attract more attention, maybe this is not fair. Yes, that is the brain. My favorite hypothesis about the brain is that we only use 10% of the brain. The idea is attractive, because it suggests the possibility that, as long as you can waste 90% of the parts put to good use, we may become wiser and more successful, or more innovative. This may motivate us to work harder, but, unfortunately, there is no justification for this hypothesis.
First, we have to ask a very important question. - What's 10%? If one refers to the 10% of the area of the brain, then to refute this idea would be easier. We called the use of a functional magnetic resonance imaging techniques, neuroscientists can observe the machine scans the image to determine when people think about something when, which part of the brain is active. Like a grip or let go of such a simple action or say a few words like such a simple process, a range of active brain is far more than one-tenth. Even if you're bored, your brain is busy preparing before - perhaps it is controlling breathing or heart rate such a function, or recall the things you want to do.
Perhaps 10% refers to the brain cells. But that is not the case. When there is excess nerve cells, they either have died after degradation, or be mobilized elsewhere nearby. Our brain cells will not have nothing to do, otherwise the price paid is too great. In fact, our brains consume us tremendous resources. According to cognitive neuroscientist Sergio Della Sala say, let the brain tissue itself alive requires 20% of the oxygen we breathe.
Needless to say, naturally it does sometimes create strange design. But the evolution of the brain is 10 times the size of what we need, it is more surprising, after all, such a great guy to spend a lot of our resources for survival, not to mention the case of human help, there may therefore maternal dystocia, and even death.
But there are still a lot of people staring at us only use 10% of the brain hold this view. On this argument neuroscientist at University College London, UK Sophie Scott participated in a first aid course spread out, someone in a first aid course first aid teacher training courses to ensure that, even if a head injury is not a big deal, because " in fact, "we only use 10% of the brain. He not only 10% of this value is a mistake, but he was also on the assessment of the impact of brain damage is also wrong. Even a small injury will have a huge impact on human functions. The teacher may not attempt to aid in the guidance of a professor of the course up the nerve, and the provision of a rumor Scott immediately.
Then such a biological or physiological basis no idea how it will be widely disseminated? Follow it to find the original source of the statement is not easy. American psychologist and philosopher William James in 1908, "human strength," a book mentioned, our "mental and physical resources are being utilized only a small part of the available resources." He for us to accomplish more optimistic, but did not give a specific percentage. 10% of the data in the 1936 edition by Dell? Carnegie wrote the best-selling book "How to Win Friends and Influence People" has been mentioned in the preamble, and sometimes, people say Einstein is the origin of this statement. But Professor Della? Sarah looking cited attempts failed, and those who study Einstein Archives did not find any records. So, it seems that this has become a mystery.
There are two other phenomena caused this misunderstanding. Nine tenths of brain cells called glial cells. These logistical cells - white matter, for the other 10% of the cells - neurons, providing physical and nutritional support part of the nerve cell functions in addition to supporting Consideration is gray matter. Maybe people heard that only 10% of the cells to function, and also put forward the hypothesis that we can make good use of glial cells. But these are completely different cell types. They will all of a sudden transformed into nerve cells, the brain gives us extra motivation, is completely impossible.
That said, there are still a small group of patients showed a difference in their brain scans. In 1980, a man named John. Rob British pediatrician mentioned in the journal Science, his hydrocephalus patients with almost no brain tissue, but also move freely. Of course, this is not to say that other people can take advantage of additional features of the brain, only shows that these people have adapted to the unusual circumstances.
Of course, if we make great efforts to research in this area, we will learn new things, and neural plasticity in the field there are more and more evidence that our brains can change. But we did not involve new areas of the brain. We just between nerve cells or to create a new contact, or no longer need to abandon our old contacts.
The most interesting we found on this hypothesis is that when you tell people when this hypothesis can not be established, do not mention how disappointed people. Perhaps 10% of the data is too attractive, it offers great potential for promotion. We all want to get better, if we work hard, we all want to do it. Unfortunately, however, it is to find the part of the brain not being used does not mean that a miracle will happen.
