Fig. 2.
Representation of the inhomogeneous fiber. The first half of the fiber (cells 1–30; gray) is poorly coupled (Rg = 60–70 Ω-cm) and the second half of the fiber (white) is well coupled [gap junction resistivity (Rg) = 1.5 Ω-cm]. ρoeff is varied between 0.5 and 2.5 kΩ-cm in the first half of the fiber and kept constant at 0.5 kΩ-cm in the second half of the fiber. Rg(PC), Rg of the poorly coupled region of the inhomogeneous fiber; Rg(WC), Rg of the well-coupled region of the inhomogeneous fiber.
