Neuroseparation

Neuroseparation or cephalic isolation is the surgical removal of the head from the body. It is done during when conducting neuropreservations.

The Alcor Life Extension Foundation performs neuroseparation below the neck at the level of the sixth cervical vertebra at a temperature near 0 ºC. The head is then perfused with cryoprotectants via the carotid and vertebral arteries prior to deep cooling. For neuropreservation patients cryopreserved before the year 2000, neuroseparation was performed at the end of cryoprotective perfusion via the aorta.

Neuroseparation is also conducted during neuroconversion, the conversion of an already cryopreserved whole-body patient into a neuropreservation patient.
