Liaison between neuroscience and education has resulted in significant advances in our understanding of the neurobiological learning requirements of individuals with reading disability, the neuroplasticity of the developing brain, and the participation of the right hemisphere in reading. Research in neural network theory and cortical oscillations suggests that the hemispheres collaborate in high-level language processes. The right hemisphere specializes in coding low frequencies of the speech envelope and interhemispheric cognitive control, while the left is specialized for local high frequency, verbal computations. Studies in neural networks, and cortical oscillations which controlled for reading-level, converge in identifying an impaired right hemisphere circuitry of frontoparietal attention networks as a primary cause of dyslexia. Occurring in early development, such a dysfunction would have a cascading negative effect on phonemic processing in the left hemisphere dorsal reading network. Such integrative hemispheric cooperation suggests a more comprehensive approach to early reading instruction and interventions in dyslexia.
神经科学与教育的结合,使得我们对阅读障碍者的神经生物学学习需求、大脑发育的神经可塑性以及右脑在阅读中的参与有了更深入的理解。神经网络理论和皮层振荡的研究表明,大脑两个半球在高级语言过程中协同工作。右脑专门负责编码语音包络的低频和半球间认知控制,而左脑则专门负责本地高频、言语计算。对神经网络和皮层振荡的研究,在控制阅读水平的情况下,得出了一致的结论,即前额顶叶注意网络的右脑回路受损是阅读障碍的主要原因。这种功能障碍发生在早期发育中,会对左半球背侧阅读网络中的语音处理产生级联的负面影响。这种整合的半球间合作表明,对于早期阅读教学和阅读障碍的干预,需要采取更全面的方法。
