Mathematical Modeling in Physiology

This minisymposium is sponsored by Society for Mathematical Biology, Inc.

2:00 PM-4:00 PM
Room: Sidney Smith 1087

Mathematical models have proved valuable in understanding the behavior of physiological structures. The mathematics must be rich enough to capture important phenomenon, such as oscillations, bursting, pattern formation and signal propagation. At the same time, a mathematical model must be simple enough to yield to analysis, yet provide insight into the complex dynamics present in vivo. Mathematical modeling and analysis of four physiological systems will be presented in this minisymposium. Several questions may present themselves, among them: How does a noisy signal affect the transmission of neural signals? What role does diffusion play in signal propagation? What role does bursting play in cell activity and signal processing? This minisymposium will bring together scientists in biology, biomedical engineering, mathematics, medicine and physiology, who share a common interest in understanding the dynamics of physiological structures.
