Human Intelligence Through Brain Scans

Researchers at Yale led a study that demonstrate fluid intelligence (defined by abstract reasoning) can be measured by the functional connectivity of 268 specific brain regions. Emily Finn, co-author of this study, said, “The more certain regions are talking to one another, the better you’re able to process information quickly and make inferences.” Mostly, fluid intelligence had to do with the connections between the frontal and parietal lobes. The stronger and swifter the communication between these two regions, the better one’s score in the abstract thinking test.Earlier, same researchers have demonstrated that a person’s brain activity appears to be as unique as his or her fingerprints. Using brain imaging data, researcher were able to identify individuals.
