| Abstract | Electroencephalography (EEG) signal is generated by electrical activity of human brain. EEG topographic maps (topomap) give an idea of the brain activation. Brain Mapping may be used to relate the connectivity and functionality of the brain through imaging. Brain functional connectivity helps to find functionally integrated relationship between spatially separated brain regions. Brain connectivity can be measured by several methods. The classical methods calculate the coherence and correlation of the signal. Brain connectivity can also be measured by using nonlinear methods like mutual information, generalized synchronization and phase synchronization. In this paper, we have developed an algorithm to map neural connectivity in brain by using full search block matching motion estimation algorithm. We have examined the behavior of human brain throughout a specific activity using Oddball Paradigm. In the first step the EEG signal is converted into topomaps. The activation between consecutive frames is tracked using motion vectors. Vector median filtering is used to obtain a smooth motion field by removing unwanted noise. In each activation several paths between brain lobes have been tracked. |

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.
