1) I'm concerned with what they tasks will they be having the rats perform once it's out of testing phase. Why set up rats to follow commands that are outside the rat's inclinations -- i.e. go straight across a lit, cleared area, etc.

2) What animals will they expand this to should it prove successful.

3) Scientists controlling another creature's mind to have it do the scientist's direction seems as arrogant an experiement with life as cloning does, at least to me.

Doesn't this seem dreadfully 'Stepford Wife'-ish or slavery oriented to you? Or am I over-reacting here?
