Human brains are harder to be intelligent

Humans have created penicillin, space shuttle, computers, even artificial hearts, and many other great inventions. But human scientists can hardly create but such great inventions.

Scientists at the University of Cambridge (UK) said that the ability of the human brain has reached its peak and it is difficult to be more intelligent. They argue that in order to become smarter, the human brain will need an extra amount of energy and oxygen - but we simply cannot provide these conditions.

The team analyzed the structure of the brain and determined how much energy the brain cells need to stay active. Dr Simon Laughlin, a professor of neurobiology at Cambridge University, said : 'We have found that the brain needs to consume energy to remain active and these requirements have limited productivity. work and creativity of the brain '.

Dr. Simon Laughlin also said that for the brain to work more efficiently, it needs a lot more energy because the brain is looking for new relationships and it has to link information from many sources. different.

Other scientists also think that the human brain cannot function better. They found that smart people have the best nerve system, which helps to transmit signals very quickly between different areas of the brain.

However, scientists believe that this nerve system also needs a large amount of energy to function effectively, but people currently cannot provide such a large amount of energy, so we cannot become smarter.
