Strong features of the study include a large sample size; careful attention to subject and control characterization, scan acquisition, and image analysis; and recognition of the importance of age and gender effects on brain morphometry.

A central tenet of structural imaging studies is that size matters. Critics of the principle contend that the unimportance of size within a broad range of extremes is demonstrated by healthy children with similar IQs having as much as a 50% difference in brain volume,² robust differences in brain sizes between males and females with similar functional capacity, and the paucity of established correlations between the size of any given brain structure and cognitive abilities. However, from a computational science perspective it seems likely that the number of neuronal . . . [Full Text of this Article]
