&#x27;&quot;In this study, the researchers predicted how well people would do on a cognitive test by analyzing fMRI scans of 126 subjects in the Human Connectome Project, a five-year initiative to map how areas of the human brain communicate with each other. The subjects performed motor, memory, and intelligence tests, including a pattern completion test that measured abstract reasoning—what neuroscientists call fluid intelligence.<p>Their connectomes, it turned out, had a lot to do with how well they scored. ...A strong connection between the frontal and parietal lobes, especially, meant a high fluid intelligence score.&#x27;<p>This is an interesting result as well, that connection between different areas of the brain predict abstract reasoning ability.
