Magnetic fields applied to the brain can be used to treat ADHD, improve memory and even control your behavior and sense of morality. But unless you’re a neuroscientist, it’s hard to see the physiology of this phenomenon, other than trying to interpret colorful brain scans.
The following video accomplishes this beautifully. And not just because it cuts off a science editor’s ability to speak.
Watch below as New Scientist editor Roger Highfield’s recitation of "Humpty Dumpty" is interrupted by magnetic interference. Vincent Walsh from the Institute of Cognitive Neuroscience at University College London used magnets to shut off Highfield’s speech center, the British science mag reports.
Transcranial magnetic stimulation, as this is called, is a useful way to inhibit specific regions of the brain. Along with boosting visual memory, it can make you better at math, for instance. It’s even been shown to alter moral judgments; DARPA is studying the technique for use in battle helmets, allowing soldiers to manipulate brain functions to boost alertness, relieve stress or reduce the effects of traumatic brain injury.
Walsh and colleagues are studying the use of the technique to treat migraine and stroke, New Scientist says.
At publication time, PopSci editors were as yet unwilling to duplicate the experiment.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.

I'm guessing it can also be used to pacify dissidence (or kill them), which is what the government is REALLY after.
That looks like a scary-as-fuck experience. I would never volunteer for that, not because I'm afraid of damage (I don't think there'd be any), but because the sensation of suddenly losing your ability to speak, especially in the middle of a sentence, must be terrifying.

At the University I attended there was a professor that experimented with transcranial magnetic stimulation. He did an experiment where he was able to use TMS to shut off the centers of the brain that allow a person to lie. The participants of the experiment where asked to lie on a questionnaire, when the TMS was applied they were not able to lie. This experiment made me very uncomfortable and I wondered why this experiment did not generate a news story(maybe it did...who knows?). Anyway... seeing this article just reminded me of that experiment.
Can I get get a DIY?
This is scary (af) on a lot of levels.
1. It might just make some permanent changes
2. Some military apps might not be too nice
- inhibit some moral objections
- enable continued operation when injuries are bad
and you should really be trying to save your own
life
(you get the idea)
3. Who knows what some unscrupulous folks might try to do
with tech like this.
4. Somebody will try to use it to get high
Oh well, it's out there now -- one can only hope
this fellow walsh has a slight stutter, i wonder if he had this before or if it occured since his experimenting commenced or if it has gotten worse or better as he further experiments on his brain?
Please! You're still using New Scientist as a source? What a RAG. These guys are/were linked with the East Anglia climate change debacle and you're still supporting/quoting them. SHAME ON YOU.
Probaly what we observed here was something completely different given New Scientist's reputation for reporting consensus rather than science.
either way, I WANT ONE i need some copper coils and im done right just a high power magnet, right?
Anti-prior device!
I've been watching too much stargate...
Come on, everyone knows that the soul is what conrtols everything including moral behavior. This is obviously the devil's work HAHA
Seriously high power...several kilogauss from the look and sound of it, that has to be modulated fairly quickly to have an effect.
Changing magentic fields move electrons...makes sense that they are creating current flow in your brain that disrupts your abilitiy transmit information between neurons...especially if any of the chemicals are slightly ionic...
Basically with a big enough modulating magnetic field I can do a bunch of things to physical objects as well as brains...the power required to generate these magnetic fields are pretty high...nothing you'd be able to put on a helmet...maybe in an airport or medical facility, but not really someting portable. Also, this is NOT a subtle technique...basically an MRI system generates these type of fields.

i thought so, too!!!!!!!!!!!
wonder if it works on replicators?
