These caveats do apply, but Alcor uses technology they licensed
from 21CM and we *did* see much improved brain cryopreservation in
the rabbit model, in the single case we did back then. It's been a
long while since I left the company, so things are bound to have
improved.

How the average patient looks, is entirely different story (in
most of the cases, you can't perfuse properly, and have to settle
for straight freeze for large portions of the brain).

What you do see in this pictures is how good cryopreservation
can get in the best case. This is the data set we should be planning
to work with.
