| Abstract | A multichannel high-throughput microchip device integrating arrays of Pt microelectrodes modified with Pt-black nanoparticles for the measurement of spike activity from individual cells was fabricated. The microfabricated microelectrode arrays with a good noise level and appropriate impedance on glass substrate combined with homemade multichannel acquisition system as a powerful tool for neuroelectrial monitoring. The activity of cortical neurons was recorded at spontaneous and excited state on the system. The changes in activity patterns of cultivated cortical neurons induced by the treatment with chemical (KCl) were analyzed. A detailed analysis of chemical effects on the neurons electrophysiological behavior including spike and burst activity is presented. The cells showed obviously improved activity after stimulation by K+, the firing frequency and firing amplitude increased as well as the higher number of firing channels. The application of chemical (KCl) stimulation modulates the electrophysiological activity of cortical neuronal networks with respect to the spontaneous activity intrinsically shown by the cultured neurons. The proposed approach coupled to MEAs and detection system allows for a more extensive use of in vitro cultured neurons for neuropharmacological applications and which supply the promise of MEA technology as a high throughput, rapid screening method for toxicity testing of chemical. |

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.
