> Llorens-Martin said she began carefully collecting and preserving brain samples in 2010, when she realized that many brains stored in brain banks were not adequately preserved for this kind of research. I was always curious about it, and this piece shed some light over it: as death is a process where all cells undergo chemical transformation, all you add to stop the process and preserve some state also induces changes. So, depending on how you preserve something, you will also lose information and won't be able to further study something. Interesting how we have a long road regarding preservation of bodies and how much we still can improve about it.
