[Simnibs-discuss] Relative influence of cortical surface-based parameters on resulting efield model

[Mccalley, Daniel]

Hi all,

I was wondering how/if different features of the cortical surface are modeled in SIMNIBS.

While I'm sure coil-to-cortex distance accounts for a substantial portion of variance between individual electric field size/strength, I would imagine that local features of the cortex such as cortical thickness, orientation/complexity of gyri and/or sulcal depth are incorporated into the modeling. Are these features somehow weighted or accounted for when modeling electric fields?

If so, what is the relative weighting or contribution of these factors in determining the efield model? or alternatively, is it known what portion of individual variance these features explain?

Best,
