Dynamic collaboration of reading neural pathways driven by the processing demands

Dang Min, Wenqi CAI, Fakun CHEN, Xiaojuan Wang et autres

摘要： 建构统一的认知和神经生理模型是词汇阅读认知神经科学研究面临的核心问题。阅读的认知理论模型一致认为阅读是语音和语义加工通路分工协作的结果, 认知神经科学研究也表明词汇阅读是背侧和腹侧神经通路动态协作的结果。为了系统地阐述阅读网络的这种动态协作机制, 结合神经功能和生理基础两个层面, 从以下三个方面对最新研究进展进行系统疏理：首先, 指出潜在的加工需求是背/腹侧神经通路动态协作的实质; 然后进一步阐明潜在加工需求驱动了不同正字法深度下背/腹侧神经通路的分工合作模式; 最后, 深入剖析了潜在加工如何通过语言经验塑造了神经通路间的动态协作。从而揭示出阅读神经通路动态协作的实质可能是特定任务下加工需求驱动的结果, 这种动态协作可能成为跨语言普遍的词汇阅读理论模型。

Helical carbon nanofibers modified with Fe 2 O 3 as a high performance anode material for lithium-ion batteries

Ting Qing, Naiqiang Liu, Yongzhong Jin, Ge Chen et autres

Helical carbon nanofibers (HCNFs) modified with Fe2O3 (Fe2O3/HCNFs) with a particle size of about 10-20 nm were first introduced for potential use as a novel anode material for lithium-ion batteries (LIBs). Fe2O3/HCNFs were successfully prepared via a chemical liquid deposition (CLPD) method …

The Interaction Between Phonological and Semantic Processing in Reading Chinese Characters

Dang Min, Rui Zhang, Xiaojuan Wang, Jianfeng Yang

The contemporary models of visual word recognition reached a consensus on a cooperative division of labor between phonological and semantic processing. We examine how reading is influenced by the interaction of two processing in Chinese character reading since the ideographic property of …

The neural circuit of semantic processing and its dynamic cooperation with the neural circuit of phonological processing in reading Chinese characters

Dang Min, Xiaojuan Wang

摘要： 从神经网络的角度研究词汇阅读的大脑神经机制, 需要揭示语义和语音神经回路的动态协作机制, 而语义加工神经回路是探讨该问题的一个亟待解决的瓶颈问题。利用汉字表义的独特性, 以形旁语义作用的神经机制为切入点, 计划开展的4个fMRI实验拟探讨汉字阅读的语义神经回路及其与语音回路的动态协作机制。实验1利用多参数相关分析技术, 识别与汉字语义和语音属性相关的功能脑区; 实验2和实验3集中考察形旁语义加工的大脑神经机制, 深入探讨形旁语义作用的实质, 揭示汉字阅读中语义加工的神经回路; 实验4通过建构汉字阅读的动态因果模型, 考察在刺激驱动和任务调节下, 阅读相关脑区联结模式的动态变化, 阐明语义和语音神经回路的相互协作机制。研究结果将从跨语言的角度, 阐明阅读神经网络的内部动态机制, 为联结主义理论提供神经生理方面的直接证据; 并为基于脑科学的教育教学和阅读障碍矫治等实践应用提供理论依据。
