In a book of this character we would expect to find articles on surgical relief of pain, stenosis of the spinal canal producing intermittent claudication in the legs, intracerebral hemorrhage, normal pressure hydrocephalus, brain scanning, and monitoring of patients with multiple injuries. Less obviously anticipated are articles on computers, data processing, radiation detection, and other features of "Space-Age Research Methods." Implanted electrodes may measure metabolic functions in the brain or may be part of Lewin's prosthesis to be placed over the visual cortex so that stimulation might produce images to make the blind "see." Dougherty and Schneebeli use electron micrographs to explain the anti-inflammatory effects of steroids; Lillehei's group illustrate their concepts of vasodilation in physiology and treatment of shock. A central biasing mechanism is invoked by Melzack to explain phantom limb pain, while Feindel's group report on external and internal radioisotopic and fluorescein techniques for studying cerebral circulation.
