What makes a person smart?
Differences in intelligence have so far mostly been attributed to differences in specific brain regions.
However, are smart people's brains also wired differently to those of less intelligent persons? A new study supports this assumption.
In intelligent people, certain brain regions are more strongly involved in the flow of information between brain regions, while other brain regions are less engaged.
Differences in cognitive abilities - and the resulting differences for example in academic success and professional careers - are attributed to a considerable degree to individual differences in intelligence.
Researchers from Goethe University in Frankfurt combined functional MRI brain scans from over 300 people with modern graph theoretical network analysis methods to investigate the neurobiological basis of human intelligence.
The study shows that in more intelligent persons certain brain regions are clearly more strongly involved in the exchange of information between different sub-networks of the brain in order for important information to be communicated quickly and efficiently.
On the other hand, the research team also identified brain regions that are more strongly 'de-coupled' from the rest of the network in more intelligent people. This may result in better protection against distracting and irrelevant inputs.
What do you think makes a person smarter or more intelligent than their peers?
