| Abstract | Retinal ganglion cell receptive fields have been successfully described using the difference of Gaussians model introduced by Rodieck. As the basic elements of retinal receptive fields are well described by the Gaussian function, it is natural to model receptive fields beyond this level as a convergence of Gaussian subunits. In this paper the full two-dimensional solution to the problem of calculating the response to drifting gratings of a model receptive field composed of Gaussian subunits is presented. The subunits are not required to be radially symmetric, any number is allowed, with any temporal phase delays; and responses are predicted to gratings of any spatial frequency at any orientation. This solution will greatly extend the range of receptive fields that can be modeled as a convergence of Gaussian subunits, including those with orientational and directional selectivities. |

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.
