Detailed explanation-1: -Grey matter refers to unmyelinated neurons and other cells of the central nervous system.
Detailed explanation-2: -Both the cerebello-parietal component and the frontal component are associated with intelligence.
Detailed explanation-3: -In healthy adults, greater intelligence is associated with larger intracranial gray matter and to a lesser extent with white matter. Variations in prefrontal and posterior temporal cortical thickness are particularly linked with intellectual ability.
Detailed explanation-4: -Overall, larger brain size and volume is associated with better cognitive functioning and higher intelligence. The specific regions that show the most robust correlation between volume and intelligence are the frontal, temporal and parietal lobes of the brain.
Detailed explanation-5: -Researchers say white and gray matter are both necessary for general intelligence, but they perform different functions. Gray matter represents information processing centers in the brain, and white matter represents the network or connections between those processing centers.
