X-Message-Number: 13843 Date: Mon, 05 Jun 2000 07:31:31 -0700 From: Mike Perry <> Subject: Higher Temperature Storage In view of Doug Skrecky's posting, #13841, we can ask of the higher temperature storage that has been proposed as an accompaniment of a new suspension protocol would really be best for longterm preservation of identity-critical information. The higher-temperature storage may indeed lead to reversible cryopreservation, yet over many decades it could still promote degradation of memory information in the brain that would not occur at liquid nitrogen temperature. The cracking that occurred in lowering to this temperature might still be a favorable tradeoff. Something to investigate. Actually, though, I am inclined to optimism about storage of brain tissue at -130, in view of the successes Suda had with brainwave recovery at the much higher storage temperature of -20.
