Emerging scientific evidence has established that the human brain remains biologically viable hours after circulatory arrest. The fine structure of the “postmortem” brain persists even longer and gradually changes in a time- and temperature-dependent fashion. Today, our simplistic “binary” definitions of death increasingly look dated, lack scientific rigor, and need to be updated.
Contemporary cryopreservation technologies permit ice-free preservation of the fine structure of the brain at ultra-low temperatures. These technologies can be used to induce metabolic arrest in terminally ill patients to prevent further deterioration.
Cryonics (or human cryopreservation) is an experimental medical procedure that aims to stabilize critically ill patients at low temperatures with the aim of restoring them to good health in the future. As our understanding of the biology of death, vitrification technologies, and molecular medicine are converging on the technical feasibility of cryonics, the time has come for the medical community to embrace metabolic arrest as a treatment option.
This aim of this website is to increase the understanding of cryonics and advocate its use as an elective medical procedure. We also report on related topics such as rejuvenation technologies, dementia prevention, neuroprotection after cerebral ischemia, and medical nanorobotics.
