A five dimensional brane cosmology with non-minimally coupled scalar field to
gravity has been considered in a Jordan-Brans-Dicke frame. We derive an
effective four dimensional field equations on a 3+1 dimensional brane where the
fifth dimension has been assumed to have an orbifold symmetry. We have noticed
that the evolution equation for the matter component stuck to the brane is
non-trivially coupled to the scalar field living on the brane and the bulk.
Finally we discuss some cosmological consequences of this set-up.Comment: 8 pages. Major revision. Conclusions where change
