| Abstract | Research on the neural basis that underlies decision making in humans has revealed that these processes are mediated by distributed neural networks that incorporate different regions of the frontal lobes, the amygdala, the ventral striatum, and the dopamine system. In the present article, we review recent studies in rodents investigating the contribution of these systems to different forms of cost-benefit decision making and focus on evaluations related to delays, effort, or risks associated with certain rewards. Anatomically distinct regions of the medial and orbital prefrontal cortex make dissociable contributions to different forms of decision making, although lesions of these regions can induce variable effects, depending on the type of tasks used to assess these functions. The basolateral amygdala and the nucleus accumbens play a more fundamental role in these evaluations, helping an organism overcome different costs to obtain better rewards. Dopamine activity biases behavior toward more costly yet larger rewards, although abnormal increases in dopamine transmission can exert opposing actions on different types of decision making. The fact that similar neural circuits are recruited to solve these types of problems in both humans and animals suggests that animal models of decision making will prove useful in elucidating the mechanisms mediating these processes. |

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.
