Mice get smarter with bits of human brains in their heads.

On the first try, for instance, altered mice perceived the connection between a noise and an electric shock a standard learning test in mouse research. Normal mice need a few repetitions to get the idea. Memories of the doctored mice were better too: they remembered mazes, object locations, and the shock lessons longer.
