Before revision:  However, the robustness against the extrinsic noise and the transmitted information are trade-off in the linear model and in the threshold model without SR , whereas they can be simultaneously increased in the threshold model with SR .
After revision:  However, the robustness against the extrinsic noise and the transmitted information are trade-off in the linear model and in the threshold model without stochastic resonance , whereas they can be simultaneously increased in the threshold model with SR .
