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:
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)
