Myths about the human brain
The complexity of the brain and the physical difficulty of investigating it has created many mysteries, myths and false beliefs around this organ. Here are some of the lies we hear on the street:
We only use ten percent of the brain
It is one of the most widespread popular beliefs, but it is not true: Yes, neurons make up ten percent of the brain cells, but images of the brain show that all parts remain active to one degree or another.
after the age of 30, no neurons are born
Although the regenerative power of the brain is lower than that of other organs, a mature brain can develop new neurons; this process is called neurogenesis. New neurons are born in the hippocampus, on the side related to memory and learning, and are produced by stem cells.
The left has linguistic competence in the right hemisphere
NO: Writing by a person with the right or left hand does not ensure where in the brain the linguistic ability is located. It is true that 95 percent of the right have this ability on the left side, but only 18 percent of the left have language ability on the right.
The size of the brain is important for measuring a person's intelligence
More than size, the number of neurons and the connections between neurons have something to do with a person’s mind. The size of the brain is related to the size of the person himself: similar to many other organs, the brain of men is larger than that of women, but the brain of cheeks is also larger than that of humans and cheeks are not smarter than we are.
The brains of men and women are very different.
There are some differences, but there is no consensus among scientists as to how significant they are. In addition, more differences can be found between the two brains of the same sex than between the brains of men and women.
Twins tend to have similar natures, even though they grow up apart
This is also a widely heard myth. But current research indicates that the coincidences between twins raised and educated in different environments are just that: mere coincidences. No gene has yet been discovered that decides to be a bad genius or to be a sweet tooth.
