Brain Source Localization synthetic Data

[unes1111]

Hello there
I am very new to BrainStrom and source localization in general
Is there anyway to simulate EEG data for source localization , i.e select the location of the sources and then multiply them by a leadfield matrix to get the EEG data.
My primary goal is to use this data is to validate my source localization (inverse model) method, So i want to make sure that I know where exaclty the source are
Any help would be appriciated
Best Regards
Younes

Hi Younes,

You have this menu to simulate EEG recordings from existing source maps:

If you want to attribute your own signals to the active ROIs, refer to this post:

Simulate scalp recording

After you import the subject anatomy, you should do the following: Set a default EEG cap Edit the EEG cap to fit in on the subject’s head (at least project the electrodes on the head surface) http://neuroimage.usc.edu/brainstorm/Tutorials/Epilepsy#Register_electrodes_with_MRI Compute a forward model http://neuroimage.usc.edu/brainstorm/Tutorials/Epilepsy#Register_electrodes_with_MRI Define some source activity, with the process "Simulate > Simulate generic signal" http://neuroimage.usc.ed…

Cheers,
Francois
