  It is shown that the Dirac-nambu-Goto brane can be described as a point
particle in an infinite dimensional brane space with a particular metric. This
suggests a generalization to brane spaces with arbitrary metric, including the
"flat" metric. Then quantization of such a system is straightforward: it is
just like quantization of a bunch of non interacting particles. This leads us
to a system of a continuous set of scalar fields. For a particular choice of
the metric in the space of fields we find that the classical Dirac-Nambu-Goto
brane theory arises as an effective theory of such an underlying quantum field
theory. Quantization of branes is important for the brane world scenarios, and
thus for "quantum gravity".
