On the magnetic field and the electrical potential generated by bioelectric sources in an anisotropic volume conductor

Untitled

“…The conductivity values have been shown to be irrelevant even if the volume conductor has spherically symmetric anisotropy, i e . even if the conductivity in the radial direction differs from that in the tangential directions so that spherical symmetry is maintained [6]. These results are generalized in this paper by showing that the conductivity in the radial direction can be an arbitrary function of location with no consequence on the external magnetic field.…”

Biophysics of Temporal Interference Stimulation

“…where s xx , s yy , and s zz are the conductance in the x, y, and z directions, respectively. To solve Equation 6, we used the following nondimensionalization procedure (Peters and Elias, 1988):…”

Biomagnetic functional localization of a peripheral nerve in man

“…Replacing the argument of this function, Ix(t), by u = tx/vx yields a description of the propagation of this current pattern in time and space. The compound current conductivity tensor of the tissues involved, such as bone, muscle, fat, etc., differ considerably (17)(18)(19). Therefore, the impact of volume currents can be estimated by the asymmetry of the observed MCAF with respect to they = 0 plane.…”
