Claim 14:
15. The method of claim 13, further comprising:
determining a largest frequency component of a first time-varying measurement of the CSD corresponding to a first electrode of the plurality of electrodes;
determining a largest frequency component of a second time-varying measurement of the CSD corresponding to a second electrode of the plurality of electrodes;
calculating a Fourier transform of the first time-varying measurement of the CSD at the largest frequency component of the first time-varying measurement of the CSD, wherein the Fourier transform of the first time-varying measurement of the CSD indicates the first phase;
calculating a Fourier transform of second first time-varying measurement of the CSD at the largest frequency component of the first time-varying measurement of the CSD, wherein the Fourier transform of the second time-varying measurement of the CSD indicates the second phase; and
determining a difference between the first phase and the second phase in order to determine the phase relationship between the two or more tissue regions within the target area.
