Therefore, membrane covered in myelin is effectively passive. As shown in Fig. 7, the sheath does leave small regions of the neuron cell membrane exposed, called Nodes of Ranvier, which may fire an action potential. If an active patch of membrane fires at a Node of Ranvier, current will flow to the right but will not be able to easily cross the cross the membrane because of the high Rm . Instead, most current will follow the path of least resistance and jump farther down the cable. So, in effect, the high resistance of the myelin creates a short circuit that skips quickly from one Node of Ranvier to the next.

Simulation Problems (1) Program a passive membrane with input variables of Rm, Cm, dt, endtime, Stim start, Stim End, and Stim Strength. (2) Program a passive membrane with input variables of Rm, Cm, dt, endtime, Stim start, Stim End, and Stim Strength. 23 CHAPTER 3 Active Membranes In the previous chapter we considered the response of a membrane to a small stimulus. In these situations the resistance of the membrane was linear and Iion was modeled as a simple resistor and battery in series. In this chapter, we consider what happens when a stimulus causes Vm to reach threshold.

Instead, most current will follow the path of least resistance and jump farther down the cable. So, in effect, the high resistance of the myelin creates a short circuit that skips quickly from one Node of Ranvier to the next. Multiple Sclerosis (MS) is a disease that causes inflammation and scaring of the myelin sheath leading to degradation of neural impulse propagation. The symptoms are changes in sensations, muscle spasms, a lack of coordination and balance, pain, and eventually cognitive and emotional impairment.
