Visualizing multiscale functional brain parcellations#

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

Retrieving multiscale group brain parcellations#

# import datasets module and use `fetch_atlas_basc_multiscale_2015` function
from nilearn import datasets

parcellations = datasets.fetch_atlas_basc_multiscale_2015(version='sym')

# We show here networks of 64, 197, 444
networks_64 = parcellations['scale064']
networks_197 = parcellations['scale197']
networks_444 = parcellations['scale444']

Visualizing brain parcellations#

# import plotting module and use `plot_roi` function, since the maps are in 3D
from nilearn import plotting

# The coordinates of all plots are selected automatically by itself
# We manually change the colormap of our choice
