Controlling Brain Activity With Magnetic Nanoparticles
sciencehabit writes: Deep brain stimulation, which now involves surgically inserting electrodes several inches into a person's brain and connecting them to a power source outside the skull, can be an extremely effective treatment for disorders such as Parkinson's disease, obsessive compulsive disorder, and depression. The expensive, invasive procedure doesn't always work, however, and can be risky. Now, a study in mice (abstract) points to a less invasive way to massage neuronal activity, by injecting metal nanoparticles into the brain and controlling them with magnetic fields. The technique could eventually provide a wireless, nonsurgical alternative to traditional deep brain stimulation surgery, researchers say.
I am IRON MAN...hey wait turn that off... AAAAAAGGGGGHHHHHH!!!! That hurts!!!
I only look human.
My mother is a halfling and my dad is an ogre, so that makes me an Ogreling
Can they 3d print me a new brain to erase all the memories of these crappy stories?
You know it's bad when "injecting metal nanoparticles into the brain and controlling them with magnetic fields" is LESS invasive.
I need warning so I can get drunk before I read this shit
I'm pretty sure this is our cue to throw out the tinfoil hats and embrace our new singular existence.
"Controlling Brain Activity with Magnetic Monopoles", and thought that it didn't seem like a terribly practical technique.
What could possibly go wrong?
the above is my personal opinion and does not necessarily reflect that of the little voices in my head
So, we can inject a brain and then play games with it magnetically. I'm sure no one will use it to punish people, alter their behavior at will, or to try to change rebellious people into get-along types. Oh, oh, yes - or to try to quiet their kids down to get better grades and do more homework. After all, we nail them with chemicals to do those very things. No one will try to take a solid-state shortcut. 'Cause we don't trust tech that much, do we? No siree. We don't have blind faith in our programming skill and computer use, which is what is required to pull this off.
If the brain is effected by near-field electrical activity, then it is also effected by far-field effects too. So, just use a very high gain microwave beam of low intensity, pulsed at sub 1KHz rates of verious waveforms to drive the depolarisation and electronically steer it across the head.
Now you are writing to the brain and various nervous systems of the body.
Then you can teach a computer the patterns and allow it to drive the interface. I bet you can insert words, images, etc....
i mean, c'mon man.
vinge imagined in his novel "A Deepness Upon the Sky" a paramagnetic virus that puts human brains into a form of artificial hyper-focus, very autistic. then they sit and program computers until they drop dead of constipation. they are humans pared of most personality, and it is all tuned by magnetic fields interacting with the virus which has iron atoms in its molecular structure ; a whole caste system and cruel society evolves from this technology. people who are 'focused' desire their area of focus with intense craving.

. . . injected custom-made, 20-nanometer iron oxide particles into a region of the rodents' brains called the ventral tegmental area (VTA), a well-studied deep brain structure essential to the experience of reward, which plays a central role in disorders such as addiction and depression in people
Think of Larry Niven's "wire head' addicts and the Puppeteer's Tasp in Ring World. There are potentials for both private and governmental abuse.
..as cue to Shut Up. Just yesterday for SD posting.
And I still consider the commanding authority behind this some old fart with fat cigar and a some moderately ugly looking garment.
The nano particles - metal dust from the sand thrown into the Gears Of War ????
Wireless brain electrodes? Now I'll feel even MORE anxious when I walk through a store's anti-theft gates. So much for having electrodes implanted to cure my anxiety. I imagine paranoiacs will double their tin-foil hat thickness to ensure noone accesses their brain electrodes without authorization.
is indistinguishable from Star Trek technobabble, apparently.
Post may contain irony: discontinue use if experiencing mood swings, nausea or elevated blood pressure.
98% of population voluntarily buy a Programming Device For Their Brains. And then they run the Programming Device for several hours per day.
Read Mr McLuhan on that subject. No need for hugely complicated and bullshit-ridden pseudo-electrical-engineering stuff.
Also, get yourself a PROPER electrical engineering education. Your current knowledge comes from some Maoist AgitProp Fearmonger Social Science Shitter.
They will just double the tinfoil around their Zombie-Trackers aka "smart" phones.
Sounds like the Molecular Control tech tree.
When you want to take over the world... always start with the children...
What better place to hide metal particles?
This sounds like the modern-day lobotomy. I wonder how it will be viewed a few decades from now.
what's strange about this is anti psychotic injections: invega and risperidone consta, already contain nano particles as their method of delivering the medication to the brain/blood stream. believe me, I would have never done this to myself but otherwise I'd be without a place to live right now.
Time to start selling copper mesh or paramagnetic nickle wire Faraday Beanies!
to iron-cobalt alloy foil.
Sheldon said that Leonard's mom already wrote a paper that disproves this.
