The membrane of this fiber is assumed passive. The PDE governing v ( x, t ) in this fiber is: 2 2 v m x 2 v m t v m = 2 r e I ( ( x + d ) ( x d )) u ( t ) . (1) 1. Determine the configuration of electrodes that stimulate this fiber. We need to know the position x of each electrode, its polarity, and whether it is in the intracellular or extracellular space. Make sure to document your reasoning. 2. Determine the steady-state solution of Eqn. (1). To make your job easier, you can use translation in space and superposition. 3. Without using Matlab, make a good sketch of the steady-state solution v m ( x ) computed in question 2. Assume that d . Label the axes and put all other pertinent information on the graph. Explain how you used the information that d ....
