Despite the time and research that we have dedicated to it, the human body remains a source of incognites for our species, especially when it comes to really understanding how our brain works.Its functioning is usually the center of attention of those They investigate it, but this time we want to show you brains that stand out for another reason: their shape.
Let's discover the strangest human brains of which there is a record! Their form perplexed those who discovered them and is that the typical representation they showed us at school, sometimes does not fit reality, which seems to exceed more often than we thought to fiction.Let's see these organs that both impacted!

The importance of the human brain
It is clear that the human brain is one of the most amazing organs that exists and that, despite If represents only 25% of our total weight, it is responsible for controlling virtually all our existential functions.
It is composed of more than 86 billion nerve cells that are related with each other to give rise to at least 100 billion nerve connections.What we have not yet discovered is how those connections one day, without knowing very bi in how, they gave rise to consciousness and the human mind appeared.
Despite the extraordinary nature of this organ, it sometimes fails, with greater or lesser gravity.In some cases, the amazing plasticity that has the brain makes the person adapt and that this failure does not become incompatible with life.
In the following 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.
1.The brain without wrinkles
One of the strangest human brains ever found is so strange and different from what that we are used to seeing, that you would not even be able to recognize as a brain, because it is an amorphous mass that completely lacks the characteristic wrinkles and grooves.
This anomaly is technically known as lissencephaly and is characterized, as we said, 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 supply during development or to genetic causes.
Those people who have this type of brain Stranger human usually experience a variety of symptoms, almost most 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 lissencephaly adult, although co Keep in a closet at the University of Texas.
2.The divided brain
Another of the strangest human brains known is the divided brain.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 subsequently extracted as a treatment for a wide variety of diseases, such as hysteria or epilepsy.
The reality is that some people who were 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 They require the two hemispheres to work together.
Surely this is due to what we discussed earlier about the flexibility of this organ.At birth without this type of connection between both hemispheres, it is the brain itself who tries to “ repair error ”building new connections.When the amputation of these is to at a more mature age, in addition to an unnatural way, the brain is unable to regenerate those connections and loses that connection between both hemispheres.
3.The brain without cerebellum
Another of the The weirdest human brains that exist is what is known as the half brain.The first of these weirdest human brains, that is the brain without wrinkles, is something known to science, instead, the case of the half brain is he did not know until a 24-year-old woman from China went to the emergency room suffering from nausea and dizziness..On the scan, the doctors realized that he was missing half a brain! Specifically, 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 6 years old and I don't walk until 7.
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 entire organ, so the fact that this woman reached adulthood is at least a miracle.Now this case has joined the only 9 people worldwide who survive without her cerebellum.
There is little information about how this fault affects people in adulthood, since most cases do not survive a few years, which makes e The case of the Chinese woman is exceptional.
What do you think about these cases of strangest human brains ever seen? Do you know any of the cases? Undoubtedly, our body and nature seem to have unlimited capacity to surprise us.Leave us your comments and impressions! We would love to read you!
