Without a doubt, there is nothing in the world that is as unknown as the human being, in particular, in how our brain . This is an unknown that accompanies us throughout the centuries and that we are not able to finish clearing. The general doubt is about its operation, but sometimes doubts go beyond that. Within the surprising thing of this organ, we want to speak to you today of three stranger human brains even if it fits. Not because of its operation, but because of its shape.
We are going to discover the strangest human brains of which we have record! His appearance perplexed those who discovered them and is that the typical representation they showed us in school, sometimes does not fit the reality, which seems to exceed more often than we thought fiction. Let's see these organs that impacted so much!
The importance of the human brain
It is clear that the human brain is one of the most surprising organs that exist and that, despite represent only 25% of our total weight, is responsible for controlling virtually all our existential functions.
It is made up of more than 86 billion nerve cells that are related to each other to give rise to at least 100 billion nerve connections . What we have not yet discovered is in what way those connections one day, without knowing very well how, gave rise to consciousness and the human mind appeared.
In spite of the extraordinary nature of this organ, it sometimes fails, with greater or lesser severity. In some cases, the amazing plasticity that the brain possesses makes the person adapt and that this failure does not become incompatible with life.
In the next article we want to talk about the 3 strangest human brains found and what are the consequences of their rarity for the person who owns them.
The 3 strangest human brains
1. The brain without wrinkles
One of the strangest human brains ever found is so strange and different from what we are used to seeing, that you would not even be able to recognize it as a brain, because it is an amorphous mass that completely lacks the characteristic wrinkles and furrows.
This anomaly is technically known as lissencephaly and is characterized, as we told you, by the total lack of grooves and folds on the surface of the brain , something very characteristic of the human brain. The causes of this malformation can be varied and range from viral infections in the uterus, to insufficient blood flow during development or to genetic causes.
Those people who have this type of weird human brain usually experience a variety of symptoms, almost the majority of them degenerative. They range from muscle spasms and seizures, to a wide variety of learning difficulties. One of the worst causes of having this type of brain is that life expectancy is usually much shorter, even before 10 years.
As in all things there are always exceptions, and there is an extraordinary case of a brain with adult lissencephaly, although it is kept in a cabinet of the University of Texas.
2. The divided brain
Another of the human brains Strangers that are known is the brain divided. This type of brain occurs when the connections between both hemispheres do not exist, either because it was born without what is known as the corpus callosum or because it was later extracted as a treatment for a wide variety of diseases, such as hysteria or epilepsy.
The reality is that some people who have been born with the lack of this corpus callosum seem to lead a normal life. However, those people who have been removed, lose the ability to perform tasks which require the two hemispheres working together.
Surely this is due to what we mentioned earlier about the flexibility of this body. At birth without this type of connection between both hemispheres, it is the brain itself that tries to "repair the error" by building new connections. When the amputation of these is at a more mature age, besides unnaturally, the brain is unable to regenerate those connections and loses that connection between both hemispheres.
3. Half brain
Another of the strangest human brains that exist is what is known as a half brain. The first of these stranger human brains, that is to say the brain without wrinkles, is something known by science, however, the case of the half brain was unknown until a 24-year-old woman from China went to the emergency room suffering from nausea and dizziness . On examination, the doctors realized that he was missing half a brain! In particular, the cerebellum was missing.
The cerebellum plays an important role in motor control, language, voluntary movements and balance. In fact, the mother of this girl confirmed to the doctors that she had not learned to speak until she was 6 years old and that she did not walk until she was 7 years old.
This fact is so incredible because, although the cerebellum only represents 10 percent of the total volume of the brain, it actually occupies 50% of the total neurons of the whole organ, so the fact that this woman reached adulthood It is at least a miracle. Now this case has joined the only 9 people in the world who survive without their cerebellum.
There is little information about how this fault affects people in adulthood, since most cases do not survive a few years, which makes the case of Chinese women is exceptional.
What do you think about these cases of strangest human brains ever seen? Did you know any of the cases? Without a doubt, our organism and nature seem to have an unlimited capacity to surprise us. Leave us your comments and impressions! We will love reading you!
