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

[sheraz at nmr.mgh.harvard.edu]

hi Alex,

my 2 cents, if you look at the waveform carefully, the responses follows
the same time course as the cortical responses. Putting this example will
give very wrong impression about MEG and deep sources.

Putting premature examples might not be great idea :)
