Intelligence index does not relate to brain volume

The latest study by American scientists found that human intelligence is not determined by a weak function in a certain area of ​​the brain and is not related to the volume of the brain.

According to the study, the human intelligence index is determined by the link between specific parts of the brain.

The results of this study were published on the latest National Academy of Sciences of the US.

Dr Let Gelasixier of the California Academy of Natural Sciences (USA) said that in general intelligence is determined by a special network in the brain. This network is made up of gray matter and white matter.

Gray matter is the cellular body of neurons, while white matter made by nerve fibers of neurons, and are all 'linked wires' between functional areas in the brain.

Healthy connections between different parts of the brain are very important for human intelligence.

It is known that scientists conducted tests on 241 subjects with brain damage.

First, scientists outline the location of lesions in the brain, then test the patient's intelligence index and observe areas in the patient's brain that show good and bad.

The scientists then compared the test results with the location of damage in the brain to detect areas that were not as good as the test results, which means that the area was found to be meaningful. Important meaning for human intelligence index.

The results of this study coincide with previous research results, in which the network connection in the brain plays an important role in working memory.

Job memory is a temporary memory when people store and process work-related information temporarily.

This study opens up strong theoretical grounds for the intimate relationship between intelligence and the ability to remember work that was previously confirmed by people.
