Abstract: A method of treating a neurological disorder comprises introducing an electrical stimulation lead within a patient's head, locating the stimulation lead within the 4th ventricle of the patient's head, and placing the stimulation lead adjacent the fastigium nucleus of the patient's brain. The method may further comprise stimulating the fastigium nucleus with the stimulation lead to treat the neurological disorder, for example, by increasing the flow of blood within the patient's brain.

Abstract: A method for treating a patient suffering from chronic neuropathic pain, comprises epidurally applying electrical stimulation energy to a spinothalamic tract of the patient, thereby treating the chronic neuropathic pain. The method may further comprise increasing the activation threshold of a side-effect exhibiting neural structure relative to the activation threshold of the spinothalamic tract of the patient, wherein the electrical stimulation energy is applied to the spinothalamic tract of the patient while the activation threshold of the neural structure relative to the spinothalamic tract is increased, thereby treating the chronic neuropathic pain without stimulating the neural structure.
