I would think twice about using paralytic agents in awake animals: it's
banned here in Britain, and quite a few journals won't publish papers in
which the experimental protocol violated ethical principles. Humanitarian
considerations aside, it's also *extremely* stressful and would probably
mess up your results. It isn't an easy problem to solve. Rats can be
trained to do some quite odd things with patience and the right reward.
Good luck,
