That work has been pretty thoroughly debunked. What's getting transferred is stress hormones, and you can "duplicate" the results by using animals that have been stressed (but have never seen the maze) as the donors. They don't know anything about the maze, so can't transfer any knowledge. The recipients do better in the maze because they are more alert, due to the transfer of stress hormones.

I would love to see some sources for this. Sounds super interesting. When do we get Matrix-style learning modules?
