Human neuroimaging is expanding our understanding of the biological processes that are essential for healthy brain function. Methods such as diffusion weighted imaging provide insights into white matter fascicles, growth and pruning of dendritic arbors and axons, and properties of glia. This review focuses on what we have learned from diffusion imaging about these processes and the development of reading circuitry in the human brain. Understanding reading circuitry development may suggest ways to improve how we teach children to read.
人类神经影像学正在拓展我们对健康大脑功能所必需的生物过程的理解。例如,扩散加权成像等方法可以深入了解白质束、树突和轴突的生长和修剪以及神经胶质的特性。本文综述了我们从扩散成像中了解到的这些过程以及人类大脑阅读回路的发育情况。了解阅读回路的发育过程可能有助于我们找到改善儿童阅读教学的方法。
