...spokesman for the medical center said yesterday the electroencephalograph (EEG) tests, which measure electrical activity in the brain, would be repeated this week, and all life support procedures would be continued...
...interrupt a device that is performing lifesaving functions." The experts agreed that despite the seriousness of Karen's condition, she meets none of the accepted criteria for determining death. She has not suffered "brain death," the legal measure of death in eight states-though not New Jersey. An electroencephalograph shows that there is still brain activity. She has, on occasion, breathed spontaneously, for up to half an hour, though most experts doubt that she could do so much longer without the aid of the respirator...
...Association adopted a similar standard. As a guide to determining brain death, many doctors-and the Kansas and Maryland state legislatures-have adopted a set of standards suggested in 1968 by researchers at Harvard University. These require, among other things, that doctors wait at least 24 hours after an electroencephalograph (EEG) has shown no brain activity, then check again. If the second EEG is as flat as the first, the doctor can then assume that even if machines are keeping the patient breathing, his brain, and thus the patient, has died...
Brain Waves. Although Pinneo and others have experimented with computer systems that respond to voice commands, he decided that there might be a more direct method than speech. The key to his scheme: the electroencephalograph, a device used by medical researchers to pick up electrical currents from various parts of the brain. If he could learn to identify brain waves generated by specific thoughts or commands, Pinneo figured, he might be able to teach the same skill to a computer. The machine might even be able to react to those commands by, say, moving a dot across a TV screen...
Doctors searching for a workable definition have had to protect themselves from lawsuits and murder charges as well as protect the patient from the scalpels of overzealous transplant surgeons. Usually, they have called in an outside, objective judge: the electroencephalograph (EEG). The EEG measures electrical activity in the brain, which has displaced the heart as the recognized center of individuality. Cessation of that electrical activity is "death...
