My area of research is effect tDCS (Trans-Cranial Direct Current Stimulation) on brain potentials.
I don’t have a good knowledge in tDCS modelling but would like use it a bit in my thesis. As I have already completed 2 years of my PHD I don’t want drift into new field or code the stuff for modelling. I would like to observe how current flows into brain when tDCS is applied. I looked for tDCS modelling software and couldn’t find many in my search. I found one named SPHERES (http://neuralengr.com/spheres/?page_id=17), which doesn’t have human brain model instead have a sphere but can play with parameters (amount of current, electrodes location where tDCS is applied etc).
Could anyone please help me with a simulation software where I can play with parameters like amount of current, electrodes location where tDCS is applied etc. Any help would be really appreciated.

This site might or might not be helpful. Not sure if the software they offer meets your specifications, but its worth investigating.
In this paper (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3477710/), they just ported the SPM-segmented MRI image into COMSOL and computed the conductances. Do you have an individual brain you're targeting specifically? The field gradients are going to be very different for different individuals.
Contact Pedro Miranda from Lisbon. He has developed TDCS modeling software.
You can try SCIRun 5.0 Brain Stimulator FEM Toolkit developed at the University of Utah:

hello.
did you find a good answer to your question about TDCS?if so , can you please tell me what the answer was?
thank you.
Hello all,
Many thanks for helping me out with your valuable suggestions. I've used COMETS for my research and published the work in Journal of Neural Engineering . Please find my work here

Many thanks once again.
Hi tDCS experts,
I'd like to follow up on this question and extend it to modeling brains with atrophy, such as Alzheimer's Disease brains, rather than healthy brains.
What would you suggest based off of your experience in using these aforementioned modeling softwares?
Thanks!
Sean
I would like to add that for the atlas known as Colin27 implemented in SCIRun 5.0 Brain Stimulator FEM Toolkit we have recently made individual scalp and skull electrical conductivity estimates using parametric EIT:
