Bursting Dynamics

4:00 PM-6:00 PM
Koali (Salon 5)

A system is said to exhibit bursting dynamics when its behavior alternates between oscillation and quiescence. Bursting is prominent in many biological systems, especially in neurons. It is exhibited by individual cells as well as their populations. Understanding the biophysical and dynamical mechanism of bursting is a major problem in mathematical biology. The speakers will address this issue using various geometrical methods from bifurcation and singular perturbation theories.
