Usually the problem is not with freezing—but with thawing. Vitrification improves things further—but even without that an enormous quantity of information seems bound to be preserved. I don’t think scepticism about this has much scientific basis. We know enough about the brain, and about freezing to see that a mountain of information will be preserved.
Alcor says:
“It is a well-established fact that long-term memories are encoded in durable physical and chemical changes.”
