阅读发展的神经机制

The Neural Mechanism of Reading Development

摘要: 阅读是人类获取的一种关键能力，它加速了人类文明的进程。人类阅读能力并非是与生俱来的，而是源自于环境对人脑的塑造，是人脑可塑性的体现。对阅读发展神经机制的研究，使得研究者可以洞察大脑是如何调整和优化阅读过程的。这不仅有助于揭示阅读网络形成和发展的内在机制，也有助于进一步揭示了人脑可塑性的深层原理。除此之外，这些研究还有助于阐明阅读障碍的成因及其发展机制，为实施有针对性的阅读干预措施提供科学依据。尽管在阅读发展的神经机制领域，研究者已经取得了一定的研究成果，但依然有许多关键性问题尚待解决。比如，视觉阅读网络与语言网络之间的融合机制，以及阅读网络发展如何与个体的一般脑网络发展相互关联，都是当前研究中的难题。为了深入解答这些问题，迫切需要借助新的方法和工具，来推动阅读神经机制的研究向更深层次发展。

Abstract: Reading is a profound innovation, which promotes the process of human civilization. Numerous researches have been conducted for the neural mechanism about reading, However, there remains a paucity of study about the neural development of reading acquisition and the neural mechanisms underlying reading development is still unclear. The neural mechanisms underlying reading development shed light on how the brain adapts and optimizes the reading process, which is of great importance for neural plasticity of our brains, as well as the cause of reading disability. It also plays a significant role in improving educational practices, and developing personalized learning strategies. Recent progress in research indicates that reading development occurs in three to four distinct phases, with corresponding changes in brain function. Specifically, reading emerged as the functional specification of the left occipitotemporal regions, and the brain function became more complexity as reading development. During reading acquisition, reading development is also characterized by dynamic changes in neural pathways. Begin readers initially started to learn to read through decoding ability, which relied much on the dorsal pathway, but when reading is skilled, readers turned to the ventral pathway to enhance reading efficiency. Although substantial progress has been made in the field, the intricacies of the neural mechanisms of reading development still need further investigation. The recently developed methods now offer fresh perspectives to unravel the mechanism underlying reading development.
