The article cites two examples as evidence of fearless mice. The first example is the affected mice venturing to the center of their cage, presumably with no regard for their safety. The second example is the lack of Pavlovian conditioning in the affected mice (basically, they don't learn).
Why make the assumption that bravado is, in fact, the result of the experiment? One could instead assume even more plausible effects, such as disorentation, nerve damage (numbness), and mental retardation.

And this will be enforced... how?
