Abstract: Provided herein is method of modulating a plurality of neurons in a patient, by stimulating an area of the patient's central nervous system. The stimulation includes alternating first periods when a plurality of pulses of electrical stimulation are delivered and second periods when no pulses of electrical stimulation are delivered. The first periods have a duration of about 100 to about 400 ms and the second periods have a duration of about 500 ms to about 1900 ms. The pulses have a frequency of about 100 Hz to about 250 Hz.
