    Pierre Levan
    Dept of Radiology, Medical Physics, University Medical Center Freiburg, Freiburg, Germany
    Neuroimage 75:1-11. 2013
    ..The large contributions of pure translational parameters and of non-linear terms to the BCG waveforms indicate that non-rigid motion of the EEG wires (originating from rigid head motion) is likely an important cause of the artifact...

    Benjamin Zahneisen
    Department of Radiology, Medical Physics, University Hospital Freiburg, Germany
    Magn Reson Med 68:484-94. 2012
    ..The technique allows the observation of changes in blood oxygenation level dependent signal as a measure of brain physiology at very high temporal resolution...
