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 steadystate 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 steadystate 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 ....
