Simulating tCS Electric Fields in the Brain

We discuss here first the methodology for computing electric fields in the brain as implementd in our software. We then provide and overview as well as tips on use of our StimWeaver software and service.

StimViewer

StimViewer is the software component embedded in NIC for StarStim. StimViewer is a fast simulation engine to produce electric fields in the brain associated with a particular tCS montage.

<math>
 \operatorname{erfc}(x) =
 \frac{2}{\sqrt{\pi}} \int_x^{\infty} e^{-t^2}\,dt =
 \frac{e^{-x^2}}{x\sqrt{\pi}}\sum_{n=0}^\infty (-1)^n \frac{(2n)!}{n!(2x)^{2n}}
</math>

StimWeaver

StimView is an optimization tool based on StimViewer technology.

Using StimWeaver you can define stimulation targets in the cortex and test different montages using matching measures.

You can also use this software to define an optimization problem and send it to Neuroelectrics. Our staff will produce a mathematically optimized montage based on your specifications.
