>The position of the CTF head localization coils, pictures available in file '''fiducials.jpg''' * Around 100 head points distributed on the hard parts of the head (no soft tissues) ==== Subject anatomy ==== * Subject with 1.5T MRI * Processed with FreeSurfer 5.2 <)>> == Tutorials using this dataset == * [[Tutorials/Resting|MEG resting state and phase-amplitude coupling]]
