講 師：Roberto Barrio (University of Zaragoza, Spain)
演 題：Dynamics of excitable cells: neurons and cardiomyocytes
概要：In recent years, much attention has been paid to the description of　excitable media, such as the
　　　dynamics of the brain and heart. In both　cases, the building blocks are excitable cells, neurons, and　
　　　cardiomyocytes, and a detailed look at the mathematics behind some of　their mathematical models
　　　provides a good starting point for answering　some observed phenomena. In this talk we show how some
　　　apparently simple　phenomena, such as the spike-adding process, have important consequences　in the
　　　models and how various elements intervene behind their formation,　such as homoclinic bifurcations,
　　　fast-slow decompositions, “canards”,　the completion of the Smale topological template, the formation
　　　of Morse　surfaces creating geometric bifurcations, etc. Finally, we will　illustrate its relevance in insect
　　　gait patterns and in the formation of　cardiac arrhythmias.
