One of the main methods used to establish a relationship between intelligence and the brain is to use measures of Brain volume. The earliest attempts at estimating brain volume were done using measures of external head parameters, such as head circumference, however, such approximations proved to be inaccurate when estimating brain size. More recent methodologies that were employed to study this relationship are post-mortem measures of brain weight and volume. However, such measures also proved to be somewhat inconclusive, yielding diverging results depending on sex, which hemisphere was examined and on the type of intelligence measured.
The most widespread methodology in contemporary neuroscience to measure brain volume and size is MRI. MRI is a non-invasive technique used to study the brain structure and function (using fMRI) of living subjects. Overall, larger brain size and volume is associated with better cognitive functioning and higher intelligence. The correlations range from 0.0 to as high as 0.6, and are predominantly positive. On average, the correlation between brain volume and intelligence is between 0.3 and 0.4, with one meta-analysis of 37 studies with a total of 1530 subjects estimating the correlation to be 0.33. The specific regions that show the most robust correlation between volume and intelligence are the frontal, temporal and parietal lobes of the brain. Therefore it can be safely concluded that larger brains predict greater intelligence.
