[FieldTrip] EEG Leadfield computation for eyeballs

[Carsten Wolters]

Dear Thomas,

 

we have not yet extended our source space into the retina, so have not yet really done it ourselves, but it should principally work with DUNEuro 

https://www.medizin.uni-muenster.de/duneuro/startseite.html

https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0252431 

if you make sure that the head model and source space contain the retina

and sufficient grey matter thickness and/or high enough FEM resolution of the retina.

 

As the source might additionally then be close to the sensors, the source model might have special importance, check e.g.

https://epubs.siam.org/doi/10.1137/23M1582874

 

Best regards

Betreff: [FieldTrip] EEG Leadfield computation for eyeballs

 

Dear colleagues,

 

I am looking for a way to compute an EEG lead-field matrix for two single dipoles at the centers of the eyeballs. Has anybody worked on or ideally solved this problem? 

 

Thanks, Thomas
