| Abstract | Using functional magnetic resonance imaging (fMRI) or positron emission tomography (PET), much knowledge has been gained in understanding how the brain is activated during controlled experiments of language tasks in educated healthy subjects and in uneducated healthy subjects. While previous studies have compared performance in visual tasks, few data adopted auditory tasks, especially in Chinese-speaking individuals. In this study, we used fMRI to investigate brain activations in processing characters by auditory tasks in 26 Chinese subjects (13 illiterates and 13 literates). After comparison of the language stimuli to the control stimuli, we observed: activation regions in the literate group involve the left superior temporal gyrus (BA22), right inferior frontal gyrus (BA47), left middle frontal gyrus (BA9), right middle temporal gyrus (BA21), dorsal anterior cingulate (BA32), and left middle frontal gyrus (BA6); in the illiterate group, activations occur in the right middle temporal gyrus (BA21), left superior temporal gyrus (BA22) and left inferior frontal gyrus (BA47). Conclusively, the left middle frontal gyrus (BA9) is strongly related to Chinese character processing and this modulated brain plasticity may be acquired by literacy and education. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
