Functional and spatial hierarchical organization of increasingly language-like word forms has been proposed for alphabetic languages at the occipitotemporal cortex for visual word recognition. In the logographic Chinese language system, similar functional and spatial hierarchical presentations of brain responses to sublexical orthographic structure are beginning to be explored. In this study, we used whole-brain fMRI to show that a hierarchical coding of increasingly language-like character… Expand
Functional organization of the ventral occipitotemporal regions for Chinese orthographic processing
Abstract Previous studies have found that the orthographic representation of alphabetic languages is hierarchically organized from the posterior to the anterior parts of the left ventralExpand
A meta-analysis of fMRI studies on Chinese orthographic, phonological, and semantic processing
TLDR
The results provide better understanding of the neural networks underlying Chinese orthographic, phonological, and semantic processing, and consolidate the findings of additional recruitment of the left middle frontal gyrus and the right fusiform gyrus for Chinese character processing as compared with the universal language network that has been based on alphabetic languages.

The differences of visual word form processing mechanism between Chinese and Western pure alexia
Pure alexia is a dysfunction with simple symptoms and specific impaired regions, which happens at early stage of reading called visual word form processing, and involves visual word form area (VWFA).Expand
HEMISPHERIC LATERALIZATION FOR LANGUAGE EXAMINED WITH CHINESE CHARACTERS
The extent and nature of right cerebral hemisphere (RH) contributions to language processing remain a matter of debate. Exploiting unique features of Chinese characters, two studies investigated twoExpand
Rethinking the function of brain regions for reading Chinese characters in a meta-analysis of fMRI studies
Abstract Neuroimaging studies have proposed specific brain regions for reading Chinese characters. For example, compared to alphabetic languages, Chinese reading has revealed more activation of theExpand
Functional and anatomical dissociation between the orthographic lexicon and the orthographic buffer revealed in reading and writing Chinese characters by fMRI
TLDR
The results provide the first evidence for the functional and anatomical dissociation between the orthographic lexicon and buffer in reading and writing Chinese characters and demonstrate the critical roles of the left fusiform area and the frontoparietal network to the long-term and short-term representations of orthographic knowledge, respectively, across different orthographies. Expand
fMRI evidence for the interaction between orthography and phonology in reading Chinese compound words
TLDR
It is demonstrated that phonological activation alone is not sufficient to drive access to lexical representations of compound words, and that orthographic information interacts with phonology, playing a gating role in the recognition of Chinese compound words. Expand
Seeing Chinese characters in action: An fMRI study of the perception of writing sequences
TLDR
It is suggested that a domain-general sequence processing network is implicated in the perception of Chinese character writing and that the left fusiform encodes not only the visual configuration but also the dynamic aspect of the writing script. Expand
Neural Correlates of Chinese and Japanese Semantic Processing: A Meta-analysis
TLDR
The current meta-analysis conducted direct contrasts between foci reported in published Chinese and Japanese fMRI studies to seek convergent activation across studies and found that Chinese evoked increased right hemispheric activation than Japanese, suggesting that semantic radicals might be more beneficial to Chinese than Japanese comprehension. Expand
Effects of Literacy in Early Visual and Occipitotemporal Areas of Chinese and French Readers
TLDR
The results suggest that the effects of extensive practice can be found at the lowest levels of the visual system, and reveal their cross-script variability: Alphabetic reading involves enhanced engagement of central and right meridian V1 representations that are particularly used in left-to-right reading, whereas Chinese characters put greater emphasis on intermediate visual areas.

The Visual Word Form Area: Evidence from an fMRI study of implicit processing of Chinese characters
TLDR
Implicit processing of Chinese characters showed that when the three character types were contrasted to one another, there was significantly greater activation in the left middle fusiform gyrus during real and pseudo character processing compared to artificial characters. Expand
The Neural System Underlying Chinese Logograph Reading
TLDR
It is suggested that the left middle frontal area (BA 9) coordinates and integrates the intensive visuospatial analysis demanded by logographs' square configuration and the semantic (or phonological) analysis required by the present experimental tasks. Expand
Orthographic and phonological processing of Chinese characters: an fMRI study
TLDR
The stronger activation of the dorsal visual stream by Chinese homophone judgment pinpoints a tight coupling between phonological representation of Chinese characters and corresponding orthographic percepts, consistent with the notion of distributed parallel processing. Expand
Hierarchical Coding of Letter Strings in the Ventral Stream: Dissecting the Inner Organization of the Visual Word-Form System
TLDR
It is concluded that the left occipitotemporal visual word-form area presents a high degree of functional and spatial hierarchical organization which must result from a tuning process during reading acquisition. Expand
Brain activation in the processing of Chinese characters and words: A functional MRI study
TLDR
The results indicated that reading Chinese is characterized by extensive activity of the neural systems, with strong left lateralization of frontal (BAs 9 and 47) and temporal (BA 37) cortices and rightateralization of visual systems(BAs 17–19), parietal lobe, and cerebellum. Expand

TLDR
The results suggest that visual familiarity, phonological processing, and semantic processing all make significant but different contributions to shaping the fusiform activation. Expand

We used the activation likelihood estimation (ALE) method to quantitatively synthesize data from 19 published brain mapping studies of phonological processing in reading, six with Chinese and 13 withExpand

TLDR
This result demonstrates that the VWFA is initially plastic and becomes attuned to the orthographic regularities that constrain letter combination during the acquisition of literacy. Expand

TLDR
Overall, there are no differences in terms of hemispheric specialization between alphabetic and nonalphabetic scripts, however, differences in language surface form appear to determine relative activation in other regions. Expand
