| Abstract | The localization of active sources inside the brain is termed as brain source localization. However, when the neuroimaging technique is EEG, then it is specifically termed as EEG source localization. This problem is also referred to as EEG inverse problem. The source localization problem is defined by forward problem and inverse problem. For the forward problem, head modelling is carried out by using either analytical methods or by using numerical techniques such as finite element method (FEM), boundary element method (BEM) and finite difference method (FDM). This head modelling information is further used to localize the active regions by estimating the current density by using various inverse algorithms. This research discusses the usage of boundary element method (BEM) for the modelling of head and consequently generation of simulated data. The results have shown that by simulating dipole on the cortical surface, the simulated EEG data can be generated. Hence, after the generation of simulated data, the inverse techniques are applied for the localization of active sources. This information can be used for the estimation of active sources inside the brain during various physical activities and for localizing of brain parts for the diagnoses of various brain disorders. |

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.
