They are currents (nAm) for method='MNE' and noise-normalized versions of
these for other methods.

The `stc.vertices` are the left-hemisphere vertex numbers of the
high-resolution Freesurfer surfaces for the subject.

I have not used the sLORETA viewer so I can't comment on that, but yes it
should be possible to get these values. You can load the surfaces with
`rr_lh = mne.read_surface('subjects_dir/subject/surf/lh.white')`, then
your locations are `rr_lh[stc.vertices]`. For the right hemisphere, load
`rh.white` and use `rr_rh[stc.vertices]`.
I see that you have opened an MNE-Python issue about this, too. Perhaps we
should discuss there how to add a tutorial for the Freesurfer surfaces /
source-space information to make it clear how to get these values.
