The boy has lost 1/6 of his brain, after 3 years he still lives normally without knowing anything

He has a visual impairment but still has an average IQ.

The human brain is an amazingly amazing organ. If it is damaged a little or even extremely serious, the brain can still exploit its remaining resources to help you live.

The case of a French man who lost 90% of his brain, and this born British boy proved it.

Recently, a strange report about the brain continues to challenge scientists' understanding. The report tells the case of a 7-year-old boy, who has been removed to one-sixth of his brain and still lives normally . After 3 years, the boy has a visual impairment but still has an average IQ.

Even the scientists said that at the age of 10, the boy was still not aware of his disability, he looked like a normal person on the surface.

A boy with a 1/6 cut off of the brain, after 3 years still lives normally without knowing anything.

Because the boy's name is not allowed to be revealed, scientists call him by the nickname UD. At 7 years old, UD undergoes an operation to remove the occipital lobe and temporal lobe. The purpose of surgery is to prevent regular and incurable seizures of UD

Approximately 10% of children with intractable epilepsy must have surgery to remove part of the brain, the area that stimulates seizures to occur. For the UD, he had to remove 1/3 of the right hemisphere, the area responsible for processing visual signals and part of the language.

The consequences of the surgery make UD vision impaired on the left, even though both eyes are still bright. However, doctors began to notice a strange phenomenon, when the lateral and temporal lobes were left on the left side of the brain, taking over the tasks of the " colleague" that had been removed in the right brain.

This effect helps UD identify faces and objects on the left side of the vision.

"The only defect he has is the inability to see the entire visual field. When looking ahead, the visual information entering the left eye is not treated, but the boy can still compensate. this by turning or glancing , " said Marlene Behrmann, a neurologist at Carnegie Mellon University.

"Moreover, by monitoring changes in the brain as UD grows, we can show that the parts of the brain remain stable and reorganized over time. This provides insight into the possibility. the ability to reproduce visual function in the cortex ".

In addition to losing some eyesight, the researchers say that the defective part of the brain does not really affect UD's daily life. Before and after the surgery, the boy has an average IQ, receiving skills. His language and visual consciousness is suitable for the age.

Scientists also believe that the boy is not yet aware of his defects. On the outside, UD was no different from a normal child."I suspect that the boy is not fully aware that he is receiving a lack of [visual] information," Behrmann explained.

FMRI images showed that UD had a loss of 1/3 of the right hemisphere.

UD's case findings were compiled after researchers followed the boy for three years, with the help of fMRI functional resonators. UD is also often given visual and behavioral tests, compared to other healthy children of the same age.

In tests, UD can easily identify objects and scenes - equivalent to his ability before surgery. UD's reading ability is also above average.

"These findings show the versatility of the visual system in the development of children's brains , " Behrmann said.

"They also continue to shed light on the visual system of the cerebral cortex, which can help neurologists and neurosurgeons understand what changes may occur in the brain [when patients are affected. go there]".

At this point, researchers do not fully understand how UD's remaining brain can handle new tasks, without affecting other aspects of cognitive processing. . But the flexibility he shows may be related to his young age, when the brain is still in development.

Back in late 2017, researchers also found another 7-year-old boy who lost the entire image processing area of ​​the brain but could still see.

The bizarre cases of this report point to the fact that we still only understand a little bit of the surface when it comes to what the human brain can do. The brain's ability to reconstruct when it comes to incredible injury results.
