  The low temperature behaviour of the in-plane and c-axis conductivity of
electron-doped cuprates like NCCO is examined; it is shown to be consistent
with an isotropic quasiparticle scattering rate and an anisotropic interlayer
hopping parameter which is non-zero for planar momenta along the direction of
the d$_{x^2-y^2}$ order parameter nodes. Based on these hypotheses we find that
both, the in-plane and the c-axis conductivity, vary linearly with temperature,
in agreement with experimental data at millimiter-wave frequencies.
