| Abstract | Electroenterogram is the myoelectric signal of the smooth muscle of the small intestine. This biosignal traduces; bowel motility. However, an invasive method is necessary for placing electrodes on small bowel serosa. The aim of this paper is to relate surface recording spectral parameters of electroenterogram to intestinal motility Indexes from internal electoenterogram recordings. Bipolar electrodes where placed at different points along the small intestine serosa of two Beagle dogs in order to acquire internal myoelectric signals. Likewise two monopolar contact electrodes were situated on abdominal surface for external recording. Internal and surface signals were amplified and acquired simultaneously in fast state. Internal signals were parameterised in order to obtain intestinal motility indexes. In the same way surface recording was quantified to calculate several spectral parameters. Correlation coefficient functions are calculated and considered as results. Every spectral surface parameter reaches a high correlation with intestinal motility index of each internal recording point. Energy above 2 Hz from the external signal provides highest correlation (around 0.7). Small bowel contractile activity progression referred from abdominal surface recording point is detected. Best correlation is achieved when adjusting time lags. The energy over 2 Hz of surface recorded signal can be used to represent intestinal motility. |

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.
