Not sure where to stick this story, entertainment seems best.
According to Live Science:
When ferrets watch the mind-bending movie The Matrix, brain activity is only slightly higher than when they stare at nothing. Scientists say this might mean something about how much of your brain is in use. Ferret brain activity increased just 20 percent when looking at Keanu Reeves compared to looking at darkness, the study found.
Did they ever think that maybe it was the movie that caused such a lack of response? The Matrix had the same effect on me. I bet ferret brain usage would have increased more if they saw a ferret-sex-flick. Don’t ask me why I think this.
