Abstract

Sufficient activation of the left fusiform gyrus is important in reading ability acquisition due to its role in reading and naming, working memory (WM), and balance tasks. Recently, a newly-designed training program, Verbal Working Memory-Balance (VWM-B), has been evaluated on children with dyslexia, and its positive effects were shown on reading ability, WM capacity, and postural control. In the present study, we aimed to estimate the functional connectivity alterations of the left fusiform gyrus following training by the VWM-B. Before and after 15 sessions of training, the fMRI and other tools data were collected on a sample of children with dyslexia, who were allocated into two control and experiment groups. Data analyses showed the increased functional connectivity of the left fusiform gyrus between the left anterior temporal fusiform cortex, left and right Crus II regions of the cerebellum, and the left middle frontal gyrus. Moreover, VWM-B training significantly improved the reading and naming ability, WM capacity, and postural control of participants in the experiment group in comparison to the control. The current study findings emphasize the critical role of the left fusiform gyrus in reading ability. Moreover, it provides evidence to support the existence of cerebellar deficits in dyslexia.

言语工作记忆平衡程序训练改变左梭状回静息状态功能连通性:阅读障碍儿童的随机临床试验研究
由于左梭状回在阅读和命名、工作记忆和平衡任务中起着重要作用,因此左梭状回的充分激活对阅读能力的习得非常重要。最近,一项新设计的言语工作记忆平衡(VWM-B)训练计划在阅读障碍儿童中被评估,并显示出其在阅读能力、言语工作记忆能力和姿势控制方面的积极作用。在本研究中,我们旨在评估VWM-B训练后左梭状回功能连通性的改变。在15次训练之前和之后,研究人员收集了一组患有阅读障碍的儿童样本的功能磁共振成像和其他工具数据,他们被分为对照组和实验组。数据分析显示,左梭状回与左颞前叶梭状皮质、小脑左、右小腿II区和左额叶中回之间的功能连通性增加。此外,与对照组相比,VWM-B训练显著提高了实验组参与者的阅读和命名能力、WM能力和姿势控制能力。目前的研究结果强调了左梭状回在阅读能力中的关键作用。此外,它提供了证据支持小脑缺陷的存在在阅读障碍。

期刊介绍: DYSLEXIA provides reviews and reports of research, assessment and intervention practice. In many fields of enquiry theoretical advances often occur in response to practical needs; and a central aim of the journal is to bring together researchers and practitioners in the field of dyslexia, so that each can learn from the other. Interesting developments, both theoretical and practical, are being reported in many different countries: DYSLEXIA is a forum in which a knowledge of these developments can be shared by readers in all parts of the world. The scope of the journal includes relevant aspects of Cognitive, Educational, Developmental and Clinical Psychology Child and Adult Special Education and Remedial Education Therapy and Counselling Neuroscience, Psychiatry and General Medicine The scope of the journal includes relevant aspects of: - Cognitive, Educational, Developmental and Clinical Psychology - Child and Adult Special Education and Remedial Education - Therapy and Counselling - Neuroscience, Psychiatry and General Medicine
