为了了解半球间迁移在数字发展中的作用，我们调查了儿童数字知识的发展与大脑半球（胼胝体）之间白色物质连接完整性之间的关系。我们使用扩散张量成像（DTI）纤维束成像分析测试胼胝体的发展和性能之间的联系，符号和非符号的数字判断任务。我们对6岁儿童顶叶皮层的半球间联系特别感兴趣，因为之前的几项研究表明，顶叶皮层区域与数字技能的发展有关。我们的研究结果显示，儿童和成人之间的胼胝体连接的左，右顶叶的纤维显着的结构差异。重要的是，这些结构差异是预测儿童在数字判断任务中表现的个体差异：与同龄人相比，数字表现差的儿童在通过胼胝体峡部的纤维中表现出减少的白色物质连贯性，胼胝体峡部连接顶叶半球。
In an effort to understand the role of interhemispheric transfer in numerical development, we investigated the relationship between children’s developing knowledge of numbers and the integrity of their white matter connections between the cerebral hemispheres (the corpus callosum). We used diffusion tensor imaging (DTI) tractography analyses to test the link between the development of the corpus callosum and performance on symbolic and non-symbolic numerical judgment tasks. We were especially interested in the interhemispheric connections of parietal cortex in 6-year-old children, because regions of parietal cortex have been implicated in the development of numerical skills by several prior studies. Our results revealed significant structural differences between children and adults in the fibers of the corpus callosum connecting the left and right parietal lobes. Importantly, these structural differences were predictive of individual differences among children in performance on numerical judgment tasks: children with poor numerical performance relative to their peers exhibited reduced white matter coherence in the fibers passing through the isthmus of the corpus callosum, which connects the parietal hemispheres.
