Thanks to a new study which the journal Scientific Reports published on Wednesday, experts may now be able to understand more about how the brain of a smart person functions. In order to obtain the results they needed, cognitive scientist Ulrike Basten and her team compared the results of some intelligence tests that 309 people completed with some brain scans. They found that the results they were looking for had to do with the connections between modules.
It’s worth noting that modules are not physical parts of a person’s brain, but more of a concept. However, over the years, experts have attributed certain functions to some of them. While some have to do with the executive function, others are responsible with salience detection. This means the ability to notice details in the environment. The main idea is that in the brains of intelligent people, those modules are less connected to others.
What’s happening inside a smart person’s brain
According to Basten, the lead author of the study, it’s much easier now to detect certain anomalies in the human brain because they use a more realistic model then before. Basten also compared the connections between those modules in the brain with a social network of some sorts. People do not share the same amount of information with everyone else. For example, close friends and relatives might know more than a distant friend or relative.
The same thing happens in our brains. The experts also based this new study on some previous ones they published. Those looked at how different parts of the brain reacted in people who did better on a test that was measuring intelligence.
Still, this discovery doesn’t mean that the work is done. Also, Basten underlined that for the moment, an MRI is not going to replace an SAT test designed for measuring intelligence. While intelligence might be indeed rooted in the brain, there is no certain answer at the moment.
