Deep Brain Stimulation
Ongoing electrical stimulation of structures deep within the brain – the periaqueductal gray and periventricular gray for nociceptive pain, and the internal capsule, ventral posterolateral nucleus and ventral posteromedial nucleus for neuropathic pain – has produced impressive results with some patients but results vary and appropriate patient selection is important. One study of seventeen patients with intractable cancer pain found that thirteen were virtually painless and only four required opioid analgesics on release from hospital after the intervention. Most ultimately did resort to opioids, usually in the last few weeks of life.

Famous quotes containing the words deep, brain and/or stimulation:
“A perfect personality ... is only possible in a state of society where man is free to choose the mode of work, the conditions of work, and the freedom to work. One to whom the making of a table, the building of a house, or the tilling of the soil, is what the painting is to the artist and the discovery to the scientist,—the result of inspiration, of intense longing, and deep interest in work as a creative force.”
—Emma Goldman (1869–1940)
“Let every woman ask herself: “Why am I the slave of man? Why is my brain said not to be the equal of his brain? Why is my work not paid equally with his? Why must my body be controlled by my husband? Why may he take my labor in the household, giving me in exchange what he deems fit? Why may he take my children from me? Will them away while yet unborn?” Let every woman ask.”
—Voltairine Decleyre (1866–1912)
“The lore of our fathers is a fabric of sentences. In our hands it develops and changes, through more or less arbitrary and deliberate revisions and additions of our own, more or less directly occasioned by the continuing stimulation of our sense organs. It is a pale gray lore, black with fact and white with convention. But I have found no substantial reasons for concluding that there are any quite black threads in it, or any white ones.”
—Willard Van Orman Quine (b. 1908)
