    A M Howseman
    Wellcome Department of Cognitive Neurology, Institute of Neurology, London, UK
    Magn Reson Imaging 16:1-11. 1998
    ..Our data, in accordance with that of Bandettini et al., suggest that recoupling between blood flow and oxygen extraction is not a general phenomenon in the human brain when visual stimuli are presented for an extended time...
