Within the framework of modified gravity model namely Slotheon model, inspired by the theory of extra dimensions, we explore the behaviour of Dark Energy and the perturbations thereof. The Dark Energy and matter perturbations equations are then derived and solved numerically by defining certain dimensionless variables and properly chosen initial conditions. The results are compared with those for standard quintessence model and $$arLambda $$ ΛCDM model. The matter power spectrum is obtained and also compared with that for $$arLambda $$ ΛCDM model. It appears that Dark Energy in Slotheon model is more akin to that for $$arLambda $$ ΛCDM model than the standard quintessence model.
