Shared and unique functional connectivity underpinning rapid naming and character reading in Chinese
Although a few neuroimaging studies have examined the role of rapid automatized naming in reading, they have all been conducted in alphabetic orthographies and have focused on brain activation. The present study investigated the shared and unique functional and effective connectivity of Chinese character naming with alphanumeric (digits) and non-alphanumeric (objects) RAN in 20 Chinese university students by using fMRI. Compared to RAN objects, character naming recruited an additional connection between the visual word form area and the left superior temporal gyrus. Compared to RAN digits, character naming recruited more connections between the language-related regions in the right hemisphere. Character naming had similar connections in the language-related regions with RAN digits and in the right hemisphere with RAN objects. These results support the notion that RAN is a “microcosm” of reading and integrates neural resources involved in object identification and naming.
期刊介绍：
The Journal of Neurolinguistics is an international forum for the integration of the neurosciences and language sciences. JNL provides for rapid publication of novel, peer-reviewed research into the interaction between language, communication and brain processes. The focus is on rigorous studies of an empirical or theoretical nature and which make an original contribution to our knowledge about the involvement of the nervous system in communication and its breakdowns. Contributions from neurology, communication disorders, linguistics, neuropsychology and cognitive science in general are welcome. Published articles will typically address issues relating some aspect of language or speech function to its neurological substrates with clear theoretical import. Interdisciplinary work on any aspect of the biological foundations of language and its disorders resulting from brain damage is encouraged. Studies of normal subjects, with clear reference to brain functions, are appropriate. Group-studies on well defined samples and case studies with well documented lesion or nervous system dysfunction are acceptable. The journal is open to empirical reports and review articles. Special issues on aspects of the relation between language and the structure and function of the nervous system are also welcome.
