Freezer Storage

Post by jordansparks »

It looks like we will be moving our formalin-fixed brains from refrigerator storage into freezer storage. Yes, this will require some cryoprotection as a step after fixation. The freezer will be -20 C, which is much warmer than the -196 C achieved with liquid nitrogen. This means that the brains will not be in a solid state but will instead still be in liquid. In layman's terms, they will not be frozen even though they are in a freezer. There is probably not much advantage in doing this, but we decided that more neuroscientists might agree that this is preserving the necessary information. Since one of our claims is that we are simply using the best techniques available to mainstream science, this is important. There are scientific papers describing storage at -20, and mainstream scientists would appreciate this additional step.

In order to facilitate this, we are building a walk-in freezer that is about 40' long, 17' wide, and 10' high. That's a huge freezer. And it will all be inside our reinforced concrete vault. Hopefully, we will run out of space some day after about 3,400 brains. At that point, we will build a second vault. The other half of our vault is refrigerator space, which is handy for a variety of purposes, but probably not permanent storage. If the freezer ever fails (and it will), we can get it fixed fairly quickly. This would not cause damage to the brains. They wouldn't "thaw" or anything. Even if the freezer was down for months, it probably wouldn't really be a big deal.
