We examined the relationship between structural brain variation and general intelligence using voxel-based morphometric analysis of MRI data in men and women with equivalent IQ scores. Compared to men, women show more white matter and fewer gray matter areas related to intelligence. In men IQ/gray matter correlations are strongest in frontal and parietal lobes (BA 8, 9, 39, 40), whereas the strongest correlations in women are in the frontal lobe (BA10) along with Broca's area. Men and women apparently achieve similar IQ results with different brain regions, suggesting that there is no singular underlying neuroanatomical structure to general intelligence and that different types of brain designs may manifest equivalent intellectual performance.
我们使用基于体素的形态学分析方法，对智商分数相当的男性和女性的MRI数据进行研究，以探究大脑结构变异与一般智力之间的关系。与男性相比，女性在与智力相关的白质区域更多，灰质区域更少。在男性中，智商与灰质的相关性在额叶和顶叶（BA 8、9、39、40）最强，而在女性中，最强的相关性出现在额叶（BA10）以及布洛卡区。男性和女性显然通过不同的脑区获得了相似的智商结果，这表明一般智力不存在单一的潜在神经解剖结构，不同类型的大脑设计可能表现出同等的智力表现。
