Visualizing multiscale functional brain parcellations
=====================================================

This example shows how to download and fetch brain parcellations of
multiple networks using :func:`nilearn.datasets.fetch_atlas_basc_multiscale_2015`
and visualize them using plotting function :func:`nilearn.plotting.plot_roi`.

We show here only three different networks of 'symmetric' version. For more
details about different versions and different networks, please refer to its
documentation.
