| Abstract | The role of the ryanodine receptor (RyR) in modifiability of synapses made by the basket interneurons onto the hippocampal CA1 pyramidal cells was examined in rats. Associating single-cell RyR activation with postsynaptic depolarization increased intracellular free Ca2+ concentrations and reversed the basket interneuron–CA1 inhibitory postsynaptic potential into an excitatory postsynaptic potential. This synaptic transformation was accompanied by a shift of the reversal potential from that of chloride toward that of bicarbonate. This inhibitory postsynaptic potential–excitatory postsynaptic potential transformation was prevented by blocking RyR or carbonic anhydrase. Associated postsynaptic depolarization and RyR activation, therefore, changes GABAergic synapses from excitation filters to amplifier and, thereby, shapes information flow through the hippocampal network. |

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.
