I don't think ASC would be any cheaper than ALCOR's current method, it
might even cost more, but I do think it would be better, possibly much
better.  With ASC you'd still have to carefully infuse the brain with
cryoprotectant, its just

with ASC you'd also infuse it with glutaraldehyde. And for the long term
you'd still have to store the brain in liquid nitrogen at -196C.  Actually
-135C would be slightly better for both methods, going colder than -135
produces some cracks, but the cracks are very narrow and its pretty obvious
which parts belongs where so little information would be lost by the
cracks, and as liquid nitrogen boils at -196
its simpler and cheaper to store things at that temperature.
