Scientists have long known that there is some electrical activity in the body, and that a change in the normal action may be a warning of disease. The knowledge has been used to diagnose ailments of the heart (by electrocardiograph) and of the brain (by electroencephalograph). Could the same principle be applied to cancer...
...three hours, each of the 40 snoozed in two sections of his laboratory (he could tell they were really asleep by means of an electroencephalograph, a brain machine with electrodes and straps reminiscent of electric chairs). Twenty students slept undisturbed; while the other 20 slept, records repeated the word list 30 times at intervals...
...famed Ether Dome of Massachusetts General Hospital, a blond British electroencephalographer named William Grey Walter unveiled his invention-a yellow box, resembling a deep-freeze unit, full of vacuum tubes, condensers, switches, wires. Walter applied to a patient's head the electrodes of an electroencephalograph (a machine that traces the peaks and valleys of the brain waves, helps to diagnose epilepsy, brain tumors, etc.). Then he attached his analyzing machine to the electroencephalograph...
...patient's brain waves traced their wavering lines on the electroencephalograph, Walter's machine swiftly interpreted the message, wrote its analysis on a tape. Said Walter: "The analysis . . . [reveals] . . . components 4, 7, 12 and 24 cycles per second." (Translation: brain waves were coming in prominently at those frequencies.) The fascinated delegates applauded warmly; in ten seconds the machine had reached a conclusion that would have taken them hours...
...breathes can be pumped away to simulate altitudes up to 60,000 feet. As the Gs begin to multiply, a television tube will stare him in the face, flashing his tortured grimaces to a screen in the control room. Elaborate instruments will study his fluttering heart; an electroencephalograph will record his troubled brain waves. An X-ray motion picture camera will photograph the slithering of his internal organs. Before his eyes, little lights will flash. In his ear a buzzer will buzz. He can put out the lights and still the buzzer by pressing the proper buttons. When...
