Has anyone ever used brainstorm to source intracranial EEG from a subdural grid to a sulci/gyri octal onset?
Localizing the source of subdural grid data is tricky because of the numerical instabilities due to the proximity of sensors to the cortical sources. We have looked at this issue a while ago and indeed these errors need to be under careful control. Developing the handling and analysis of intracranial and basic electrophysiological recordings is in Brainstorm’s development plan. You can use Brainstorm to review and process your iEEG and ECOG data, but no source analysis is available as of today.
