Passive Membranes,body can be characterized by their electrical properties, the nervous and muscular system in particular use electrical impulses to communicate information between cells. In this chapter, we will explore the basic principles of cellular electrophysiology which may be applied to any cell in the body.

Active Membranes,d . was modeled as a simple resistor and battery in series. In this chapter, we consider what happens when a stimulus causes . to reach threshold. The result is that . no longer behaves linearly. The nonlinearity of the membrane is represented in a circuit model as the . in Fig. 3.1.

Propagation,patch of membrane to the next, and so on, around the cell. Likewise, electrical impulses spread down dendrites to the soma by moving from one patch of membrane to the next. A similar process is involved in the spread of electrical impulses from the axon hillock down the axon. These waves of electric

The first half of this chapter will focus largely on the work of Roger Traub’s research group on simulating thousands of multicompartment neurons. The s
