What do you guys think? I mean electrode stimulation can galvanize cells and may deal with this. But magnetic stimulation?

 

[Microglia]

This actually seems legit at first glance. I haven't checked the literature so I can't comment anything useful but I saw one in action recently and it definitely at the very least stimulates areas of the brain. Whether it is an effective treatment, well that I'd have to do a literature search for.

Edit: just skimmed a paper on it in a good journal (but haven't thoroughly reviewed literature):

Definitely not snake oil, but can't say whether it would work in depression without the evidence.

A magnetic field creates an electric field.

More evidence is likely needed but some researchers are interested in rTMS for Parkinson's as well.

I'm pretty sure that's the opposite.

Evidence is lacking but some researchers are interested in rTMS for Parkinson's as well.

I don't imagine it working as well as deep brain stimulation though, at least not in the later stages when all nigral neurons have died.

That's right. The MD in the video on the website said the opposite thing, I did not think it over.

I wouldn't think so, but I don't think they are trying to replace DBS with rTMS. The vast majority of dopaminergic neurons are already gone before the later stages.

Yah, but you have compensatory upregulation of D1 receptors, i.e why you don't feel any symptoms until you have lost over 95% of neurons. But yah, I don't know what exactly the application would be then though at that point.
But regardless, it's interesting stuff. I'd like to hear research on it when it comes out.

More like 80-85%, but you get the picture.

It works both ways.

It's actually correct both ways. Faraday's law + Lorentz force law.

Nope it works both ways. Think Induction cooker, or those giant anti-theft devices, and take physics.

Yeah, didn't you all take the MCATs, where this was on the test?

I got the one question where you had to guide a charged particle through a magnetic field. Which is the same idea; magnetic field-->Inducing changes in charged particles or inducing a current.

Ya. Current carrying wire creates a magnetic field. A stand alone magnetic field causes electrons to move through the field creating a current... but don't the e- already have to be moving to feel the magnetic force though??

I wonder is TMS has been used involuntarily and to what extent.

Electrons in orbitals are always moving. Hell, everything is moving.
