   Abstract:
   The effects of anisotropy on potential gradient calculations in muscle tissue are investigated in an idealized two dimensional geometry. The percent of area above a gradient threshold (PAAT) is calculated in an uniform applied field and in a non-uniform field created by two point sources near the tissue. The percent RMS difference in PAAT between nominal anisotropic and isotropic conductivities in the uniform field is 37.6% compared to 3.3% in the non-uniform field. For the problem considered, an accurate anisotropy specification is required in uniform fields while an isotropic representation may be used in non-uniform fields.
