It has been shown recently that phantom-like behavior of DGP scenario can be extended by incorporation of the curvature effect via inclusion of the Gauss-Bonnet term in the bulk action. It is possible also to realize self-acceleration on the normal branch of the DGP scenario by modification of the induced gravity on the brane in the spirit of gravity. The purpose of the present study is to treat these issues in a unified manner: we study the phantom-like nature of a modified induced gravity in the presence of the Gauss-Bonnet effect.
