Subject: straight freezes

M.Darwin says in #4927:

All I can say here is that I know a number of neurobiologists and TEM 
people who are going to suggest that your results might be the same if you 
first put your patients' brains through blenders: hell, if you do that, you 
won't even have to straight-freeze, you can just pour in the 
cryoprotectant.

Thats pretty imaginative, but be sure to video tape the procedure so that
future doctors can back out the damage done by the blender blades.

One of the main points I've picked up from this straight freeze thread is that
the cost savings of a straight freeze over a cryoprotectant freeze are small
since most of the costs are tied up with getting the body quickly, cool-down
and long term storage costs.  Steve Bridge guessed the savings would be of the
order of 15K.  Therefore, all the negatives associated with a straight freeze
outweigh the small cost savings.  I'm happy to leave it at that and I enjoyed
your feedback.
