In a provocative 1974 article entitled “Harvesting the Dead,” Willard Gaylin explored potential uses of “neomorts,” or what are currently referred to as “heart-beating cadavers”—that is, humans determined to be dead by neurological criteria and whose cardiopulmonary function is medically maintained by ventilators, vasopressors, and so forth. Medical research was one of the potential uses Gaylin identified. He pointed out that tests of drugs and medical procedures that would have unacceptable health risks if performed on living human subjects could be performed on neomorts without any health risks. According to Gaylin, the potential benefits of such research could be enormous, including not subjecting patients to ineffective or harmful medical procedures and eliminating delays in providing effective therapies to dying patients.
