Dear Fieldtrippers,

I have a question about the source space selection for MEG/EEG source

Some source localization algorithms restrict the reconstruction to sources
located on cortical surface. To implement such kind of algorithm, I used
mne_setup_source_space to create a source space on cortical surface. By
default mne_setup_source_space creates a decimated dipole grid on the
white matter surface. Although this setting is widely used, some papers
create a source space on the gray matter surface instead. Are there any
specific reasons for selecting any of the two options?
