| Abstract | We proposed an approach to searching for a new drug that suppress increased daytime sleepiness induced by dopaminergic drugs during treatment of Parkinson’s disease. The search is based on the results of analysis of the effects of neuromodulators (dopamine, adenosine, and acetylcholine) on the mutually dependent functioning of the neuronal circuit motor cortex-basal ganglia-thalamus-motor cortex, which is involved in motor activity, and neural networks that regulate the sleep-wakefulness cycle and contain histaminergic cells of tuberomammillary nucleus and cells of the lateral hypothalamus, which express hypocretin/orexin and melanin- concentrating hormone (MCH). We used the unified rules of modulation of synaptic transmission, which we previously proposed. Our analysis suggests that to suppress increased daytime sleepiness it is necessary to decrease the dose of dopaminergic drugs and use drugs that contain antagonists of adenosine A1 and A2A receptors (for example, caffeine). These antagonists have an antiparkinsonian effect because they, like dopamine, can modulate corticostriatal outputs and, hencethus, facilitate motor activity. In contrast to dopaminergic drugs, they do not cause dyskinesia and cognitive disorders. Antagonists of A1 and A2A receptors also have anti-somnolent effect because they decrease MCH concentration and prevent the depressing action of endogenous adenosine on the activitiesy of cells that release orexin and histamine. Maintenance of high concentrations of orexin and histamine should promote wakefulness. |

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.
