Mapping Brain Networks to Gauge Intelligence

A study from the University of Wurzburg reveals that intelligence is a global property of the brain, influenced by distributed connections rather than specific regions like the prefrontal cortex. Using fMRI data from over 800 individuals, researchers found that brain-wide connectivity better predicts general, crystallized, and fluid intelligence. This challenges existing models focused on localized brain areas and suggests that intelligence involves complex, system-wide brain interactions.
