Creating nice brain graphics for publication - software ?

Hi,

may I ask how the brain graphics (e.g. Fig 2, Fig 2 etc.) were  created in the paper: Standardizing the intrinsic brain: Towards robust measurement of inter-individual variation in 1000 functional connectomes. NeuroImage, 80, 246–262. doi:10.1016/j.neuroimage.2013.04.081

What kind of software did you use?

greetings :)
