ABSTRACT
This chapter discusses membrane models involving the time behavior of electrochemical activity in excitable cells. These models are systems of ordinary differential equations where the independent variable is time. Electrical activity in plant and animal cells are caused by two main factors: First, there are differences in the concentrations of ions inside and outside the cell; and second, there are molecules embedded in the cell membrane that allow these ions to be transported across the membrane. The chapter examines the action potential of an electrically excitable cell.
