| Abstract | The present study investigated the role of dopamine receptors within the nucleus accumbens in place conditioning induced by D-amphetamine. Previous work has shown that conditioned place preference can be established by intra-accumbens infusion of amphetamine. The present study further examined whether bilateral co-infusion of the selective dopamine receptor antagonists with D-amphetamine into this region would disrupt the development of conditioned place preference induced by intra-accumbens amphetamine treatment. Bilateral infusions of D-amphetamine into the nucleus accumbens at the dose of 10 microg per side significantly induced conditioned place preference. At the tested doses of 1 microg and 10 microg, either the selective D1 dopamine receptor antagonist (SCH23390) or the selective D2 dopamine receptor antagonist (raclopride) infused with the high dose into the nucleus accumbens significantly blocked the development of conditioned place preference induced by intra-accumbens amphetamine treatment. Furthermore, the sole infusion of SCH23390 or raclopride into the nucleus accumbens produced little or no place conditioning effect. It is concluded that the dopamine D1 and D2 receptors in the nucleus accumbens are critically involved in the development of amphetamine induced conditioned place preference. |

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.
