介绍:
For the first time, the scientists have discovered two groups of genes directly linked to human intelligence.
Called M1 and M3, these so-called “gene networks” appear to determine how smart a person is by controlling his memory, attention, processing speed and reasoning.
The scientists liken the genes to a football team. When every player is in the right position, the brain appears to function perfectly, leading to clarity of thought and what we think of as quickness or cleverness. However, when the genes are in the wrong order, they can lead to dullness of thinking, or even serious cognitive impairments.
The scientists have also discovered that the two gene networks, each of which contains hundreds of genes, are likely to be under the control of master switches. If they can find it, they will switch on intelligence for everyone.
“We know that the genes play a major role in intelligence, but until now we haven’t found out which genes are relevant,” said Dr. Michael Johnson, lead author of the study.
The research is at a very early stage, but scientists are determined to do further research on whether it is possible to use this knowledge of gene networks to boost brain power.
Remarkably, they have found that some of the same genes that influence human intelligence of healthy people are also the same genes that cause brain diseases if changed suddenly.
Dr. Johnson said, “Intelligence is governed by large groups of genes working together, like a football team made up of players in different positions. When faced with lots of complex information, the genes in the human brain will work together to make new memories or sensible decisions.”
This research could help provide insights into better treatments for intellectual disabilities.
