Plot the head model inside MRI to check anatomical alignment¶

MNE-HCP facilitates source level analysis by supporting linkage between MRT/anatomy files and the MEG data. Here, inspect the head model that is used to compute the BEM solution.

from mne.viz import plot_bem

storage_dir = op.expanduser('~/mne-hcp-data')
subject = '105923'
subjects_dir = storage_dir + '/hcp-subjects'

We assume that all directory structures are set up. Checkout hcp.make_mne_anatomy() to achieve this necessary step. See also Extract essential anatomy information.

plot_bem(subject=subject, subjects_dir=subjects_dir)

Out:
