Transcranial Magnetic Stimulation project - part 2

[pgqneto]

your previous butterfly coil didn't work? I mean the one with regular wire.

[bkraz333]

@pgqneto Nope. It may have been a lousy design, or I just didn't target the motor cortex accurately enough.

[pgqneto]

@bkraz333 you said your job involves TMS machines. are the coils of TMS devices made with grounding brade or flat copper? I've done 15 sessions of TMS of a Neurosoft device. rTMS actually. I also am an electronic technician. I inttend to build my own TMS device. Yes, I think you would need a larger capacitor bank to make it work with the butterfly coil because it is like 2 singular coils in series but you said you're not going to buy caps anymore... you got a nice workshop.

[bkraz333]

@pgqneto I used to work with researchers who used TMS machines -- not at the TMS machine manufacturing companies. I believe most commercial TMS coils are solid copper for better conductor/space efficiency.

Can I use this to control the minds of my enemies?

Brain washing, mind control 1:03 I believe the Government are the best :)

your new name is egon

[vk2zay]

I've always wanted to try this, but was a bit cautious about triggering a seizure... Now I am feeling more confident. :)

[bkraz333]

@vk2zay If you use single pulses, you are very unlikely to cause a seizure or any other ill effects. Beware of using repetitive pulses (eg 30Hz for 1 second), as this has been shown to cause lasting effects.

Nice Delorean shirt.

[abulmagd3]

Another question, can this thing get you high??

[bkraz333]

@abulmagd3 No.

[abulmagd3]

you trust your science too much to mess with your brain that way

[bkraz333]

@abulmagd3 Science is the process by which we make logical conclusions based on our observations of the universe. It is how knowledge is created. If you can't trust that, what can you trust?

[onesevenfiveone]

hey man i'm only 18 so i don't know if what i'm saying would work, but if you rearrange the capacitors in the capacitor bank so more are in parallel with each other and not series, wouldn't that increase the capacitance of the bank overall?

[bkraz333]

@onesevenfiveone You are right, arranging more capacitors in parallel will increase the bank capacitance. The total energy storage will be the same though, since the maximum allowed voltage will be lower with fewer capacitors in series. Total stored energy is 1/2 C V^2. In this application, the voltage must be high enough to overcome the coil's inductance -- otherwise any capacitance/voltage combination should work in theory. As it turns out my pulses are too short, so I might rearrange.

[johnello]

The reason why indians wear thoughs head things that cover their head is just a cover up for people or w.e to be able to control people by hiding it in thoughs hats

[ejonesss]

judging by the uf and voltage of the capacitors it looks like you can use the large caps from old computer power supplies and save your self money

junk power supplies can be obtained from your local computer repair shops, dumpsters and maybe your local electronics recycling center if they will let you take electronics

[Grundalizer]

Try shutting the lights off or closing your eyes and then trying for the visual center

Brian Reading Methods made easy :)

[300000hp]

Nice one! What's your day job? I was wondering for a long time, what you do for a living? I guess it's somehow connected with medical appliances?

[bkraz333]

@300000hp I build MRI-compatible computer hardware (mice, joysticks, keyboards, etc) that is used in brain-imaging research studies. Recently, TMS has also been used inside MRI scanners so that researchers can monitor brain activity while also causing direct stimulation.

[nonickisfreefthat]

Don't melt your brain,mate:D Nice vid,thanks!

[uberscientist]

Awesome! I haven't been able to get that kind of reaction from my machine, I don't have a HV supply that can do 1kv. I'm glad to see another home experimenter getting results with this technology :) abovesobelow (. com) /TMS/

[v01d4d3pt]

I was able to produce a coil to self stimulate using an electromagnetic field based neural stimulation. It uh has therapeutic potential. and stuff. I totally like the feeling of being blank. ECT is barbaric and should be stopped the skull is a large dialectric shocking the skin is like shocking the outside of an insulated wire in order to charge a battery in-circuit. idiotic. to notice the carnage caused to the brain by ECT watch the calf area of the leg of a patient being shocked.

[TheFreak1ger]

Mad scientist at self experiments :o

[orbiter8]

Flippin' eck Ben be careful. We don't want a deep fried Ben on our hands :)

[RussellTuan]

maybe sometimes shock will cure something.at least i know i fell better after shock.

[daito]

wow

[jeriellsworth]

Sweet!

[pikuorguk]

Youtube video 6b5HhR4ZNfE does something similar with speech which was on UK TV last year sometime.

[hr1100]

Hey, why don't you get some animals and experiment on them?

[antekone1]

Isn't this dangerous? I mean, you don't know the neuron structure in your brain and the way the neurons are laid out. Don't you think that by artificially stimulating neurons you're damaging the network?

[lexichronicle2]

@antekone1 I seriously doubt it'd doing any damage. TENS machines send current directly into the body tissue and are fine, this is even weaker. The sections of the brain that control primary life supporting functions, like our heartbeat, is buried right at the core, and this coil is struggling with just the surface. However, if that coil were to for some reason short directly to his skin, it could trigger a seizure or kill him.

[Vlakpage]

@lexichronicle2 Well but here you have kV and kA, that's MW in short bursts which could induce some damaging field/currents. Maybe you're right but it sure doesn't look safe to me.

[lexichronicle2]

@Vlakpage MW pulses yep, but not very large coils, so not much field. I had a quick search and discovered the maximum field strengths are usually 1 or 2 teslas, which is about the same as an MRI scan. This magnetic stimulation thing is miles and miles behind the scanning technology. A MEG scanner can pick up a few thousand neurons firing and is accurate to about 1-2kHz. Whereas the stimulation seems to be entire regions of the brain and one or a few pulses.

[angryDAnerd]

I hope you never get the idea of building a death ray from anywhere

[89rafa]

this scares me a bit.

[googacct]

I remember in one of my particle accelerator books, there is a formula to add specific values of L and C to add higher frequency components to the pulse and improve the rise time. Essentially you would be creating a pulse forming network.

[oisiaa]

You know that Dos Equis who is the most interesting man in the world? I think you have him beat Ben! You are amazing in the nerdiest way possible!

[masteranza]

Wow, can't say how much I waited for the second part! Any plans for memory stimulation or frontal cortex?:)
