People only use 1/10 intelligence?

There is a concept that has existed for a long time in the scientific community in general, the medical community in particular that people can still be more intelligent if we know 'exploit' the unused areas of the brain. . The truth is that this story has heated up much debate.

Compared to other body parts, the brain seems to receive the most attention with many scientific studies on it, most notably the question of whether or not humanity is only use 10% of the brain's actual capacity. This hypothesis, if proven, would mean that we have the right to hope for even more great achievements when the remaining 90% are 'exploited'. Unfortunately, this is a very misconception.

So what does that 10% include? Using functional magnetic resonance imaging (fMRI), neuroscientists have placed volunteers inside the CT scan machine and observed how the brain is activated when they do or meditate. think of something. The result is just a simple action like squeezing and loosening your hand or saying a few words that make more than 1/10 of your brain work. Even if you think you're doing nothing, your brain has done a lot of things like controlling breath functions and heart rate or reviewing the list of jobs.

The remaining 90% of the brain has not been 'exploited' yet?

So when is the 10% number referring to the number of brain cells? Again this is also incorrect. Any excess nerve cells will degenerate and die or be invaded by other nearby areas, simply because there are no useless cells. To survive, brain tissue consumes up to 20% of the oxygen we breathe, according to cognitive neuroscientist Della Sergio Sala, and a brain that has grown to the point that only needs to use 1/10 of the ability. The reality seems to be very odd because such a large size is so easy to affect our lives.

So how can an idea with very little biological and physiological basis make it possible for many people to think so much?

In 1908, American psychologist and philosopher William James wrote in 'The Energies of Men' : 'What we are using is only a fraction of the true physical energies. and our spirit '.

Although optimistic that mankind can achieve more breakthroughs, he does not mention the mass of the brain or the number of cells and does not give a specific percentage. 10% is the number stated in Dale Carnegie's best-selling book in 1936 entitled 'How to Win Friends and Influence People' with the proof of Albert Einstein. However, in all archives about Albert Einstein, one cannot find a single line that addresses this information.

Explaining this misunderstanding, experts say it is possible that 90% of cells in the brain are glial cells. These are support cells, containing white matter, that supply nutrients to the remaining 10%, which are nerve cells that make up gray matter. This inadvertently causes many people to think about the ability to exploit glial cells. However, these are two completely different types of cells and there is no way to convert the glial cells into nerve cells in order to increase brain power.

However, although very rare, there are cases of brain scans that show something different. In 1980, a British pediatrician named John Lorber wrote in the journal Science that in patients with his hydrocephalus, someone had almost no brain tissue but remained active. This was later answered, it was just an adaptation to special circumstances.

Of course, more and more evidence shows that improving intelligence by approaching new things can change the brain but does not mean that doing so will help us 'exploit' a new area of Brain. Everyone wants better things and we can still be better if we try. Sadly, however, the search for an unused part in the brain will not be a viable option.
