How exactly is neuropreservation done?
The goal of neuropreservation is to preserve the whole brain without injury. The brain is therefore preserved within the head to avoid injuries that removal would cause. This has the additional advantage of preserving the nerve connections of our most complex senses (vision and hearing). “Neuroseparation” is performed by surgical removal of the body below the neck at the level of the sixth cervical vertebra at a temperature near 0ºC. (This leads to the mistaken belief that neuropreservation preserves “heads,” but the preservation target is really the brain.) The cephalon (head), is then perfused with cryoproectants via the carotid and vertebral arteries prior to deep cooling. For neuropatients cryopreserved before the year 2000, neuroseparation was performed at the end of cryoprotective perfusion via the aorta.
