Transcranial Magnetic Stimulation project - part 2

I achieved neuronal stimulation of my primary motor cortex by using a single 15-turn coil and 1700 volt charge on the capacitor bank of about 190uF. The exact position of the coil on my scalp makes a very big difference in how much stimulation is achieved in the motor cortex. I would have suspected the single coil would produce much more diffuse stimulation and positioning would not be so critical. I never got any decent neuronal stimulation with the butterfly coil.

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

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

@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.

@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.

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.

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

@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?

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