...troop question. "We have claimed for years that we were getting stronger," Thieu replied. "If it is so, we have to be willing to see some Americans leave." Thieu agreed that the announcement might help the Paris negotiations. Said Nixon: "We do not want to break the umbilical cord to your people." The troop replacement would not, said Thieu...
...pain felt? As long ago as 1826, Johannes Peter Müller promulgated the "law of specific nerve energies." He suggested that stimulation of specific pain receptors in the skin, like those for heat or pressure, sends impulses along specific nerve fibers to equally specific parts of the spinal cord and brain. This concept has since been called the "direct telephone-line system." The latest research shows that the system is by no means so simple as direct dialing. It is full of crossovers and redundancies, creating the effects of multiple conference calls and party lines...
...neurophysiologists now see it, when a man gets a shot of penicillin in the buttock, the stab sends an impulse along the nerve fibers to the fourth lumbar vertebra (see diagram). Then the impulse travels upward and soon crosses over to the opposite side of the spinal cord for its journey toward the brain. Along the way it triggers an automatic reflex that causes the man to flinch and tighten his gluteal muscle. After the impulse reaches the thalamus, a major (and evolutionally ancient) junction box at the base of the brain, where it is perceived as pain, it proceeds...
...analgesia, or relief of pain without loss of consciousness, is far more difficult to achieve. For cancer patients with intractable pain of indisputably physical origin, neurosurgeons have devised a number of radical operations. One of the commonest, for pain anywhere below the neck, is cordotomy-literally, cutting the spinal cord-a remedy that is less drastic than it sounds. In the standard operation, the cord is exposed and a small cut is made in the nerve bundles controlling the pain-afflicted area. The so-called cut may actually be a tiny electrical burn. Crue and his colleagues have just reported...
...Betty left, Martin's head began to reel again. Everything became distorted; he fell down four times just walking back to his room. He thought he was going carzy, for now he was having one of his dreams in the daytime. He was an earthworm, burrowing through a telephone cord into the receiver; Betty was in the other part of the telephone, and he was getting closer and closer to the receiver there, and something was about to happen--but before it could, he would see pictures, wildly distorted, of his old biology book's photographs of the cells...
