Abstract: We discuss causality properties of extra-dimensional theories allowing foreffectively superluminal bulk shortcuts. Such shortcuts for sterile neutrinoshave been discussed as a solution to the puzzling LSND and MiniBooNE neutrinooscillation results. We focus here on the sub-category of asymmetrically warpedbrane spacetimes and argue that scenarios with two extra dimensions may allowfor timelike curves which can be closed via paths in the extra-dimensionalbulk. In principle sterile neutrinos propagating in the extra dimension may bemanipulated in a way to test the chronology protection conjectureexperimentally.
