Jeff,

<div>You could start with checking the tutorial on minimum norm estimation. This contains a section on how you can create a cortically constrained source model using Freesurfer.</div>

I am thinking of using FieldTrip for EEG source modeling, and wish to use an FEM formulation. I have found documentation on creating an FEM head model, but am unsure how to create a matching source model. Can someone please point me to documentation for this?
Ideally I would want to place sources perpendicular to the local cortical surface. Also I would want to be able to create distributed sources combining several adjacent cortical elements.<o:p></o:p></div>
