Detailed explanation-1: -High intelligence scores have been linked with high concentrations of gray matter in certain regions of the frontal lobe.
Detailed explanation-2: -Similarly to brain volume, global grey matter volume is positively associated with intelligence. More specifically, higher intelligence has been associated with larger cortical grey matter in the prefrontal and posterior temporal cortex in adults.
Detailed explanation-3: -In healthy volunteers, total brain volume weakly correlates with intelligence, with a correlation value between 0.3 and 0.4 out of a possible 1.0. In other words, brain size accounts for between 9 and 16 percent of the overall variability in general intelligence.
Detailed explanation-4: -Both the cerebello-parietal component and the frontal component are associated with intelligence.
Detailed explanation-5: -The press release covering the findings claims researchers found that the volume of grey matter in the cerebellum could be used to predict intelligence. The volume-to-intelligence relationship strength differed in men and women, with men showing a stronger correlation between the two.
