Pilots training time cut in half with transcrainial electrical stimulation...

Turns out you can up learning rate with a small current across brain Scientific American:
Amping Up Brain Function: Transcranial Stimulation Shows Promise in Speeding Up Learning
Electrical stimulation of subjects' brains is found to accelerate learning in military and civilian subjects, although researchers are yet wary of drawing larger conclusions about the mechanism....
I believe I've also seen some posts on external (strong) magnetic fields being able to hinder or help learning as well. Strange times we live in.
This is also known as the Venkman Method.

If 2ma provides a small improvement, think what 200ma would do.

So many conflicted emotions about this. On one hand - awesome! But on the other hand, it's sad that this effect was discovered so the US military could train people more efficiently in the techniques of drone bombing. And on the gripping hand, I wonder if it holds up over time. The article says there were observed changes in the brain, but if this is like any other kind of electrical stimulation (except maybe pacemakers) it will get less effective with repeated use.
Still awesome, though.

I'm going to make my new hat of equal halves -- one side zinc, the other copper.
When I need to think slower, I'll just turn my hat around and reverse the current flow.

I once pissed on an electrical fence. I learned to never do that again. It was the fastest lesson ever. I'm 41 and I still burn myself on a stove, but you'll never see me making that fence mistake again.

fMRI accelerates learning to identify concealed objects.
Just to be clear, fMRI is not the causal agent here, it is an imaging method. But you probably meant that.

I'm guessing this would work for muscle memory, too -- reading between the lines at the wiki page suggests the mechanisms are similar. This is relevant to my interests. MAKE, get on it!

As someone who has undergone some brain stimulation experiments before (not court ordered! I was helping out a fellow grad student with his research project), I think it is safe to say that this research should be taken with an enormous grain of salt. I took part in a learning/memory type study that looked at the effect of TMS (transcranial magnetic stimulation), which is similarish to this study, and the one thing I took out of it as a scientist was that it was impossible to do a proper control study of this technology. Basically it is difficult to do something that "feels" like your brain is being zapped without actually zapping it.
The article mentions that they did controls by producing "a similar sensation in the scalp" but if it's anything like the controls used for TMS, I'd be inclined to think that it wasn't that similar at all. It was really easy to tell the difference between the "on" and "off" conditions and it's hard to imagine that this doesn't affect the subject's responses.
Which isn't to say that this isn't a real, and interesting effect. They also saw "changes" in Diffusion Tensor Imaging maps of the brain, which, although a very new MRI technique, is definitely an interesting sign that there is something real going on. Now, of course, those changes could be coming from the fact that you zapping the brain over and over, so... grain of salt and whatnot.

Also saw a recent article surveying some of the external scanning techniques that are beginning to learn how to read what's going on in there. Perhaps artichoke_enthusiast could comment...

Not quite what you meant, but on the subject of electrical stimulation to develop muscle memory, see PossessedHand (previously). Or you could take your volition out of the loop entirely.

You could partially control for the placebo effect by using local shocks that wouldn't pass through the brain.
