On this page a calculation is attempted to determine how many neurons need to survive for cryonics to work. The flaw in this approach should
It is common medical knowledge that after 5 minutes of cardiac arrest the prospects of successful resuscitation without neurological impairment become progressively bleak. But there
Under ideal circumstances cryonics patients are stabilized immediately after pronouncement of legal death by restoring blood flow to the brain, lowering temperature, and administering medications.
It has been shown that perfusability of the brain is significantly compromised after long-term (>5 min) ischemic events (the “no reflow” phenomenon). Improving cerebral blood
In “The chemistry of neuroprotection”, the author argues convincingly that there could be great benefit from a systematic and rigorously scientific study of the physical
In a review of the 1998 21st Century Medicine seminars, Cryonics Institute president Ben Best writes: “The presentations impressed upon me how much witchcraft and
One concern about prolonged cardiopulmonary support in cryonics is that its decreasing effectiveness may not be able to meet cerebral oxygen demand, and may even become detrimental.
Induction of hypothermia can reduce injury to the brain when it is deprived of oxygen. How fast do we need to cool a patient during
The blog Al Fin reports on polyethylene glycol (PEG) as an acute treatment for traumatic brain and spinal cord injury. PEG is hypothesized to confer
