...associate sounds with their sources and respond directly to external stimuli. He will also not learn to talk on schedule. But simple tests by doctors can usually discover whether the cause of such symptoms is deafness, and there is now a new tool for more difficult diagnoses, a computerized electroencephalogram. Electrodes are taped to the infant's head to measure brainwave responses to sounds. The responses are averaged by the computer, and the results are compared with those of a normal child...
...drastic as it is technically delicate. First a bunch of holes are drilled into the patient's skull; metal guides are screwed into place and steel electrodes are jabbed through the guides, as far as two inches into the brain, to make a special kind of electroencephalogram (EEC). The electrodes are left in place for three weeks or so, and repeated EEGs are taken-when the patient is asleep, during a spontaneous seizure, or when the doctors induce a seizure with a drug or electricity. The position of the implanted electrodes is changed if necessary. Then, after the offending...
Many physicians now believe that the question "Is this patient dead?" should be answered largely on the basis of his electroencephalogram (EEC or "brain wave") tracings. "Although the heart has been enthroned through the ages as the sacred chalice of life's blood," says Boston's Neurosurgeon Dr. Hannibal Hamlin, "the human spirit is the product of man's brain, not his heart." Yet generally, in legal practice, a pronouncement of death is based only upon the heart's having stopped beating and takes no account of the brain...
...moment of revelation he sees that the way to turn chaos into creativity is to stop brooding about the hobgoblins of his dreams and to start working on a film about the real people who surround him. 8½ is at least a wildly pictorial electroencephalogram, at best a fascinating ride down Fellini's stream of unconsciousness. Says he: "All I can say is that it did me good to make it. It was a liberating experience." But is that a reason for showing it publicly...
...member of Physiologist Nathaniel Kleitman's research team at the University of Chicago, Dr. Dement had helped to settle an age-old question: Is dreaming continuous during sleep? The answer is no: it is intermittent. The beginning of a dream is signaled by brainwave changes shown on the electroencephalogram and by rapid eye movements...
