== Presentation of the experiment ==
==== Experiment ====
 * One subject
 * Two runs of 10 min of resting state recordings
 * Eyes open

==== MEG acquisition ====
 * Acquisition at '''2400Hz''', with a '''CTF 275''' system, subject in seating position
 * Recorded at the Montreal Neurological Institute in 2012
 * Anti-aliasing low-pass filter at  600Hz, files saved with the 3rd order gradient
 * Recorded channels (301):
  * 26 MEG reference sensors (#2-#27)
  * 272 MEG axial gradiometers (#28-#299)
  * 1 ECG bipolar (#300)
  * 2 vertical EOG bipolar (#301)
  * 1 Unused channels (#1)
 * 3 datasets:
  * '''subj002_spontaneous_20111102_01_AUX.ds''': Run #1, 10min resting state
  * '''subj002_spontaneous_20111102_02_AUX.ds''': Run #2, 10min resting state
  * '''subj002_noise_20111104_02.ds''': Empty room recordings, 100s

==== Head shape and fiducial points ====
 * 3D digitization using a Polhemus Fastrak device ('''subj002_11022011.pos''')
 * Position of the anatomical references used for these recordings:<<BR>>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
