The degree of cortical folding found in adult human brains has been analyzed using a gyrification index (GI). This parameter permits the description of a mean value for the whole brain, but also a local specific analysis of different brain regions. Correlation analyses of the GI with age, body weight, body length, brain weight and volume of the prosencephalon and the cortex show no significant results. GI values do not differ significantly between male and female brains, right and left hemispheres or right and left sides of the superior temporal plane. The GI shows maximal values over the prefrontal and the parieto-temporo-occipital association cortex. A comparison between the rostro-caudal GI patterns of human brains and those of prosimians and Old World monkeys shows the largest difference over the prefrontal cortex. The mean GI increases from prosimians to human brains with the highest values for non-human primates being in the pongid group.
使用脑回指数（GI）分析了成年人类大脑中皮质折叠的程度。该参数不仅可以描述整个大脑的平均值，还可以对不同脑区进行局部特异性分析。GI与年龄、体重、体长、脑重以及前脑和皮质体积的相关性分析未得出显著结果。男性和女性大脑、左右半球或颞上平面左右两侧的GI值无显著差异。GI在前额叶和顶颞枕联合皮质处显示出最大值。人类大脑与原猴和旧世界猴的前后GI模式比较显示，前额叶皮质的差异最大。平均GI从原猴到人类大脑逐渐增加，非人类灵长类动物中最高值出现在猩猩类群体中。
