Dielectric behaviour of gap junction connected cells: a microscopic approach.

The dielectric behaviour of interconnected cells is simulated by taking into account the 'real' shape. In previous work, we derived the polarizability of non-spherical, shelled, particles by solving the related integral equation using a spectral decomposition. The permittivity and impedance modulus spectra of gap junction connected cells are compared with those provided by a suspension of ellipsoids (prolate spheroids) having the same shape as the individual cells connected through gap junction, and the same volume fraction.
