Drug Selectively Removes Rats' Memory

rednuhter writes "Nature online is reporting scientists have used drugs to selectively remove one memory while not affecting another. Musical tones were played to the rats and at the same time the subjects were given a mild electric shock. Half the study group were given the drug (not approved for use in humans) and then the experiment was repeated with a new tone. The following day the rats that had not been given the treatment were afraid of both tones while the treated half were only afraid of the second tone: the memory of fear of the first had been erased."

Are they sure?

Are they sure the reason is so clearcut and simple?

We took the entire study group and displayed both Tubgirl and Goatse to them, this made them all extremely nervous.
We then took one half of the group and after injecting them with a drug (not approved for humans yet) and once again shown them goatse.

The next day when we displayed goatse on the projector, only half the group were nervous.

Hypothosis 1: The drug made them forget.
Hypothosis 2: The repeated viewings made them immune to the shock (O RLY?)
Hypothosis 3: They were still drugged up from yesterday to care about the shock.
Hypothosis 4: The drug gave them super powers. Electricity makes them stronger.

I, for one, hail our super electricity feeding super rat overlords.
