Title: Modeling Biomagnetic Processes in Excitable Tissue

Director(s): Brett A. Sims, Department of Mathematics


Dates of Program: June 6 - July 15, 2005

Summary: This program will give for undergraduate students the opportunity to study and perform an interdisciplinary research in modeling biomagnetic processes in neural and heart tissue. Students will also participate in writing code (C++) for simulations. Student research will be supported by short lectures on special topics that under gird their research. The lectures will be given by the PI. The students will learn how electrical properties of neural and excitable tissue are quantified and will participate in developing deterministic models for action potential propagation and biomagnetic fields at the tissue level. Existing models involving various bioelectric current distributions such as current dipoles and spiral waves responsible for bioelectric fields will be studied and discussed. Hodgkin-Huxley and Fitzhugh-Nagumo type models will be studied and compared. Action potential models containing piecewise linear source terms for membrane dynamics will also be considered. Investigative studies will include a theoretical analysis of solutions, eigenvalues, and eigenvectors for various wave propagation models of the form . Biological applications of wave propagation will be investigated via numerical simulations. Two students will be selected to present their research at a mathematics conference.
