2-15. What were the circumstances under which cat brains produced normal-looking brain waves after being frozen?
This was reported by I. Suda and A.C. Kito in Nature, 212, 268-270 (1966).
The cat brains were perfused with 15% glycerol and cooled to -20 C
for five days and, upon rewarming and perfusion with fresh blood,
showed normal brain function (as measured by EEG). Since this experiment
was done so long ago, and technology has improved considerably since
then, there is some interest in redoing these experiments to see how
well we can do now.
The April 1992 Cryonics, volume 13 number 4 page 4, talks more about
this and gives more references. Appendix B of CRFT talks about the
plausibility of repair in general.
