Many mammal, human brain Although it has similar aspects with us, it does not have the same intelligence level as us. However, it is very difficult to determine why we are more advanced cognitively at the neurological level. To date, studies have found no significant differences between the brains of mammals. But eventually scientists discovered a difference.
Science AlertBased on the news of ‘ and the article, we wanted to convey the work of scientists to you. Here are the details of this discovery…
Astronomers have seen planets in a different galaxy for the first time!
Astronomers have discovered a planet in a galaxy about 28 million light-years away. If confirmed, it will be a significant achievement.
The human brain has fewer neuronal channels
from the Massachusetts Institute of Technology A team of researchers from MIT compared the differences between the brains of mammals. Compared to other mammals, our brains calcium, potassium and sodium much smaller numbers that allow the flow of ions such as neuronal channel exists.
The discovery of this feature, which distinguishes the human brain from the brains of other mammals, became the agenda of the scientific community. The flow in question is the connection of neurons with each other. to communicate generates electrical impulses. Having fewer of these suggests that the human brain can work more efficiently. It can also redirect resources to more complex cognitive functions.
neurologist from MIT Lou Beaulieu-Laroche“Previous comparative studies have revealed that the human brain is like other mammalian brains. So we were surprised to find strong evidence that human neurons are special.” said. Meanwhile, researchers nature published in the magazine.
Extremely low in the human brain ion channel density was outstanding compared to all other brains. The team during brain surgery epilepsy used tissue samples from patients. Apart from the human brain, the researchers examined the brains of 10 species such as mice, rats, gerbils, ferrets, rabbits and macaques. All comparison animals had significantly smaller brains than humans, of course. It may therefore be necessary to test samples of larger animals.
