Ah, the famous Segal Beagle experiment. It was a hoax inasmuch as Paul Segal and associates created such a confused media blitz in the late 1980's with their experiment that to this day most people apparently believe that the dog was frozen. It was not. It was subjected to a few minutes of hypothermic circulatory arrest, and revived. Human neurosurgical patients in fact routinely recover from much longer periods of circulatory arrest than that dog did. The reality is that cryobiologists are only now beginning to have some success at cryopreserving *isolated organs* like hearts and kidneys. The practice of cryonics today leans very heavily on projected future technologies (like nanotechnology) to heal injuries that are not reversible by current means. In cryonics, we hope to improve this situation somewhat by adapting technologies developed to cryopreserve hearts and kidneys, and apply them to cryopreserve the brain of terminal human patients.
