Here we apply a method for automated segmentation of the hippocampus in 3D high-resolution structural brain MRI scans. One hundred and four healthy young adults completed twenty one tasks measuring abstract, verbal, and spatial intelligence, along with working memory, executive control, attention, and processing speed. After permutation tests corrected for multiple comparisons across vertices ( < .05) significant relationships were found for spatial intelligence, spatial working memory, and spatial executive control. Interactions with sex revealed significant relationships with the general factor of intelligence (), along with abstract and spatial intelligence. These correlations were mainly positive for males but negative for females, which might support the efficiency hypothesis in women. Verbal intelligence, attention, and processing speed were not related to hippocampal structural differences.
在此，我们应用一种方法对三维高分辨率脑部结构磁共振成像扫描中的海马体进行自动分割。104名健康的年轻成年人完成了21项测量抽象、语言和空间智力的任务，以及工作记忆、执行控制、注意力和处理速度。在对跨顶点的多重比较进行置换检验校正后（<.05），发现空间智力、空间工作记忆和空间执行控制存在显著关系。与性别的交互作用显示，与智力一般因素（）以及抽象和空间智力存在显著关系。这些相关性在男性中主要为正，而在女性中为负，这可能支持了女性的效率假说。语言智力、注意力和处理速度与海马体结构差异无关。
