[extropy-chat] RE: freezing frogs & brain freeze helmet & Rip VanWinkle Pets

[Hara Ra]

I have the original article, appeared in OMNI magazine. Without circulatory 
access, there is no way to cool the brain rapidly enough. Conduction 
through the skull is not nearly fast enough. A major limitation is that if 
you use a really cold gas, you freeze the outer flesh. I'd have to look it 
up, but I believe there were fluids introduced through the carotids and 
jugulars. Cannulation of these is incredibly difficult, so such a device 
needs a skilled operator. If it were available and worked, we would surely 
use it!
