| Abstract | A new method is proposed for describing the shape of the induced artifact in the electroencephalography (EEG) applied transcranial magnetic stimulation (TMS) using two equivalent circuit models, the TMS equipment model and the equivalent circuit model of bioelectric measurement system. The TMS equipment circuit is switched into three modes, and one of them is the oscillation mode by a capacitance in the equipment and a TMS coil. The electromagnetic induction from the TMS coil to the brain in this mode corresponds to the TMS. The bioelectric measurement system forms a closed circuit by a bioelectric equivalent circuit and an EEG measurement system, and the TMS induces the electromotive force into the closed circuit. The artifact induced by the TMS is measured as the TMS artifact, which is appended to the measured EEG. Under some simplified approximations, the TMS artifact is expressed by two modes, the TMS oscillation mode and the discharge mode, and the solutions of the TMS artifact are solved from circuit equations for each mode. The simulation output calculated from these solutions successfully describes the TMS artifact in the measured EEG data by considering the frequency property of the bioelectric circuit parameters. |

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.
