| Abstract | A new approach to assess autonomic nervous system (ANS) activity and its response to drug action is presented. The authors' approach is based on using a cumulative plot of data obtained by power spectral analysis (PSA) of heart rate variability (HRV), in defined frequency bands, during short time epochs in rats. The substantial temporal variability in power evolving from the constant balancing nature of the ANS activity is minimized by this approach and produces a measurable index of ANS activity vs. time. The cumulative plot emphasizes the temporal response pattern of different components of the ANS and thereby facilitates the investigation of the kinetics of action of drugs affecting the ANS. The authors used this method to measure the activity of cholinergic drugs in freely moving Sabra rats. The pharmacodynamic (PD) data obtained by this method was combined with the drug concentration versus time (PK) profile to enable PK/PD modeling of the kinetics of the parasympathetic effect. |

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.
