[Neuroimaging] Use of atlas to compute Z-Scores

[Christophe Pallier]

you can use

`nilearn.input_data.NiftiLabelsMasker`

to extract the data, then it is only a matter of computing the z score
using your subject's average value in each ROI, and the corresponding mean
and std in the control group.
