摘要
发展性阅读障碍(下文简称为"阅读障碍")不仅会影响个人的终身发展,还会对社会造成沉重的经济负担,深入探讨相关的神经机制,对实现阅读障碍的早期预测和干预十分重要。以往关于阅读障碍神经机制的模型多集中于大脑,近些年的研究发现,阅读障碍也与小脑异常有关,但到目前为止我们仍不清楚两者的关系。通过总结最新的研究进展,我们发现小脑在阅读障碍中可能发挥着多种功能,且小脑异常与阅读障碍可能互为因果。在此基础之上,我们提出了"阅读中小脑与大脑的功能映射假说",旨在从一个全新的角度揭示小脑与阅读的关系,以及两者与大脑的关系。相关内容对全面揭示阅读障碍的神经机制,以及小脑在高级认知加工中的作用,具有重要的启示意义。
Developmental dyslexia(hereinafter referred to as“dyslexia”)will not only affect the life-long development of individuals,but also impose a heavy economic burden on society.Digging into the relevant neural mechanisms contributes to the early prediction and intervention of dyslexia.Established models of the neural bases of dyslexia primarily focused on the cerebrum.In recent years,extensive studies have shown that dyslexia is also associated with cerebellar abnormalities.However,it remains unclear about the relationships between the two.By summarizing recent findings,we found that the cerebellum could play multiple roles in reading and a bi-directional causal relationship may explain the associations between cerebellar abnormalities and dyslexia.Based on these findings,we proposed the“cerebro-cerebellar mapping hypothesis of word reading”.This new framework aims to reveal the relationship between reading,the cerebellum,and the cerebrum from a new perspective.This review offers important insights into the neural mechanism of dyslexia and the role of the cerebellum in high-level cognitive processing.
