  We present a mean field treatment of a strongly correlated model of electrons
in a three-dimensional anisotropic system. The mass of the bare electrons is
larger in one spatial direction (the c-axis direction), than in the other two
(the ab-planes). We use a slave fermion decomposition of the electronic degrees
of freedom and show that there is a transition from a deconfined to a confined
phase in which there is no coherent band formation along the c-axis.
