The present invention generally relates to patterned intensity modulation ofneural tissue. Certainembodiments provide a method of treating medical conditions by providing anelectrode and modulatingstimulation parameters delivered by the electrode. The stimulation parametersthat are modulated relate tostimulation intensity and are varied according to a stimulation inputparameter or time. The stimulation inputparameter can be a choice of an individual waveform (i.e. .PSI. or psi), whichmay be varied for each pulse.
