    Institute of Cognitive and Decision Sciences, University of Oregon, Eugene 97403, USA
    Neuroimage 7:255-60. 1998

    Division of Nuclear Medicine, Massachusetts General Hospital and Harvard Medical School, Boston, MA 02114, USA
    Neuroimage 38:549-56. 2007

    Rajendra D Badgaiyan
    Department of Radiology, Harvard Medical School, Massachusetts General Hospital, MA 02114, USA
    Int J Psychophysiol 55:257-62. 2005
