Methods of providing therapy to a patient are provided. In one method, the patient has a neuron to which a sub-threshold biological electrical stimulus is applied. The method comprises applying electrical noise energy to the neuron, wherein resonance between the biological electrical stimulus and the electrical noise energy is created, such that an action potential is propagated along the axon of the neuron. In another method, the patient has a neuron to which a supra-threshold biological electrical stimulus is applied. This method comprises applying supra-threshold electrical noise energy to the neuron, thereby preventing an action potential from being propagated along the axon of the neuron. Still another method comprises applying an electrical stimulus to a neuron, and applying supra-threshold electrical noise energy to the neuron, thereby preventing or reversing any neurological accommodation of the neuron that may occur in response to the electrical stimulus.
