Human jejunal smooth muscle model

This study proposes a model of human jejunal smooth muscle cell electrophysiology. This is the first biophysically based model of an intestinal SMC, and the first model of a human GI cell. The resulting cellular description is able to reproduce experimentally recorded slow wave activity and produces realistic responses to a number of perturbations, providing a solid platform on which the causes of intestinal myopathies can be investigated. Various implementations of the model were prepared by Poh Yong Cheng and provided below:

The following selected figures were generated from COR using the hJSMC model encoded in CellML.
