============================
Plot a cortical parcellation
============================
In this example, we download the HCP-MMP1.0 parcellation
:footcite:`GlasserEtAl2016` and show it on ``fsaverage``.
We will also download the customized 448-label aparc
parcellation from :footcite:`KhanEtAl2018`.
.. note:: The HCP-MMP dataset has license terms restricting its use.
Of particular relevance:
"I will acknowledge the use of WU-Minn HCP data and data
derived from WU-Minn HCP data when publicly presenting any
results or algorithms that benefitted from their use."
