The Brain Preservation Foundation has created a two-part prize for a team that can demonstrate high fidelity preservation of neural tissue.
The first part of this prize, the Small Mammal Brain Preservation Prize (for a rabbit brain) was won in 2016.
The winning team (21st Century Medicine) had to demonstrate complete ultrastructural preservation of 99+% of the animals connectome, as validated by electron microscopy.
When will the Brain Preservation Foundation announce a winner of the currently-outstanding Large Mammal Brain Preservation prize (a pig or larger animal)?
Resolution data is determined by the date of public announcement. Resolution is ambiguous if the prize is canceled, significantly altered in terms, or not awarded by 2040.
