[Mne_analysis] GSoC Update: dSPM source reconstruction for the right amygdala in the SPM dataset

[Alexandre Gramfort]

hi Alan,

nice work !

I have a few comments to make on the code so a PR on github would allow
me to comment inline.

Regarding the approach, it does what it is supposed to do in a pretty
elegant way, but
it is dangerous to only run the inverse method on such a tiny
source space. An activation from the cortex would necessarily be projected
to the amygdala. My hunch, is that an LCMV beamformer would suffer
less from this.

I think the next step would be to be able to combine a surface source space
and the deep volume source space you create.

best,
Alex
