Segmentation of the parasagittal dura mater on multi-center 3D-FLAIR MRI

Le Guan, Miao Lin, Ruiting Zhang, Xian Shao et autres

The parasagittal dura (PSD), located bilaterally alongside the superior sagittal sinus (SSS), has been increasingly implicated in cerebrospinal fluid-meningeal lymphatic communication, contributing to CSF waste clearance and immune surveillance. We assembled a training set of 55 3D-Fluid-Attenuated Inversion Recovery (3D-FLAIR) scans from …

The Behavioral and Neurophysiological Evidence of the Hierarchical Orthographic Representation of Chinese Characters

Rui Zhang, Li Ma, Min Dang, Xiaojuan Wang et autres

Studies of alphabetic languages have proposed a hierarchical organization of visual features/units for word orthographic representations. The Chinese writing system has a highly complex spatial structure in which a character is a combination of components that can be split into basic radicals …

A meta-analysis of resting-state fMRI in postherpetic neuralgia using AES-SDM

Guanzuan Wu, Yuejia Luo, Danling Guo, S. Lv et autres

Background: Resting-state fMRI (rs-fMRI) has revealed a range of neural activity patterns in patients with postherpetic neuralgia (PHN). However, inconsistencies in study design have led to conflicting findings in previous research studies. This meta-analysis used the anisotropic effect size-signed differential mapping (AES-SDM) …

The role of the left Angular Gyrus in lexical-semantic processing

Xiangyang ZHANG, Xiaojuan Wang, Jianfeng Yang

摘要： 大脑左侧角回是语言认知神经科学研究发现的一个重要语义加工脑区。该脑区在词汇语义加工中的具体功能还没有得到统一的认识, 成为研究者广泛关注的热点和焦点问题。结构上, 角回位于颞叶、枕叶和顶叶交接区, 并且具有广泛的白质纤维束连接, 这决定了它可能具有跨区域信息整合的功能。它在高水平语义表征、模态和特征信息联合表征、语义关系表征以及语义整合加工中参与激活, 可能是语义表征和加工的信息“聚合区”。然而, 左侧角回在语义表征枢纽、语义执行控制加工、默认模式网络的语义加工三方面还存在功能争论, 未来研究需要综合考虑左侧角回的解剖结构基础及其与广泛脑区连接的特点, 对角回子区域的功能进行深入细致地探讨。

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。

Time course of the integration of the morpho-semantics and the meaning of two-character Chinese compound words

Wenqi CAI, Xiangyang ZHANG, Xiaojuan Wang, Jianfeng Yang

摘要： 研究表明语素意义会自动激活并影响整词语义加工。但是, 汉语复合词识别中语素意义何时被激活以及如何参与并影响复合词语义整合的时间进程还缺乏清晰的认识。研究采用事件相关电位(ERP)技术, 构建了三类双字词材料: 语素意义与词义相关的透明复合词(如炽热)、语素意义与词义不相关的不透明复合词(如风流)、以及作为控制条件的单语素词汇(如伶俐), 对比考察双字词的首词素和尾词素语义参与复合词语义加工的时间进程。结果发现, 首字加工的早期(300~400 ms)和晚期(460~700 ms)都表现出语素效应, 即两类复合词要比单语素词诱发更负的波幅。在尾字加工的早期阶段(260~420 ms)不仅发现了语素效应, 还发现了语义透明度效应, 即不透明复合词比透明复合词诱发了更负的波幅。而在尾字加工的晚期(480~700 ms), 出现了反转的语素效应, 即两类复合词比单语素词诱发更正的波幅。结果表明了语素作为独立表征单元, 在早期加工阶段就得到了自动激活; 语义透明度在复合词早期加工过程发挥了重要作用, 透明复合词语素整合加工能够顺利获取整词语义, 而不透明复合词语素整合加工则会阻碍整词语义获取。

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 …

Orthographic and Phonological Representations in the Fusiform Cortex

Libo Zhao, Chunhui Chen, Luying Shao, Yapeng Wang et autres

Mental and neural representations of words are at the core of understanding the cognitive and neural mechanisms of reading. Despite extensive studies, the nature of visual word representation remains highly controversial due to methodological limitations. In particular, it is unclear whether the …
