This neurological\n disorder entails a loss of awareness for stimuli in the field\n contralateral to a brain lesion when stimuli are simultaneously\n presented on the ipsilateral side, even though early visual areas may\n be intact, and single contralateral stimuli may still be perceived.\n Functional MRI and event-related potential study were performed during\n a task where faces or shapes appeared in the right, left, or both\n fields. Unilateral stimuli produced normal responses in V1 and\n extrastriate areas. In bilateral events, left faces that were not\n perceived still activated right V1 and inferior temporal cortex and\n evoked nonsignificantly reduced N1 potentials, with preserved\n face-specific negative potentials at 170 ms. When left faces were\n perceived, the same stimuli produced greater activity in a distributed\n network of areas including right V1 and cuneus, bilateral fusiform\n gyri, and left parietal cortex. Also, effective connectivity between\n visual, parietal, and frontal areas increased during perception of\n faces. These results suggest that activity can occur in V1 and ventral\n temporal cortex without awareness, whereas coupling with dorsal\n parietal and frontal areas may be critical for such activity to afford\n conscious perception.<\/jats:p>","DOI":"10.1073\/pnas.051436898","type":"journal-article","created":{"date-parts":[[2002,7,26]],"date-time":"2002-07-26T10:36:44Z","timestamp":1027679804000},"page":"3495-3500","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":175,"title":["Neural fate of seen and unseen faces in visuospatial neglect: A combined event-related functional MRI and event-related potential study"],"prefix":"10.1073","volume":"98","author":[{"given":"Patrik","family":"Vuilleumier","sequence":"first","affiliation":[{"name":"Department of Neurology, University of California, Davis, CA\r 95616; Veterans Administration Medical Center, Martinez,\r CA 94553; Department of Psychology, University of\r California, Berkeley, CA 94720; National Aeronautics and\r Space Administration\u2013Ames Research Center, Moffett Field, CA\r 94035; Department of Psychology, Stanford University, Stanford, CA\r 94305; Massachusetts General Hospital, NMR Center,\r Charlestown, MA 02129; School of Psychology, Bangor,\r Wales LLS7 2DG, United Kingdom; and..."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Noam","family":"Sagiv","sequence":"additional","affiliation":[{"name":"Department of Neurology, University of California, Davis, CA\r 95616; Veterans Administration Medical Center, Martinez,\r CA 94553; Department of Psychology, University of\r California, Berkeley, CA 94720; National Aeronautics and\r Space Administration\u2013Ames Research Center, Moffett Field, CA\r 94035; Department of Psychology, Stanford University, Stanford, CA\r 94305; Massachusetts General Hospital, NMR Center,\r Charlestown, MA 02129; School of Psychology, Bangor,\r Wales LLS7 2DG, United Kingdom; and..."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eliot","family":"Hazeltine","sequence":"additional","affiliation":[{"name":"Department of Neurology, University of California, Davis, CA\r 95616; Veterans Administration Medical Center, Martinez,\r CA 94553; Department of Psychology, University of\r California, Berkeley, CA 94720; National Aeronautics and\r Space Administration\u2013Ames Research Center, Moffett Field, CA\r 94035; Department of Psychology, Stanford University, Stanford, CA\r 94305; Massachusetts General Hospital, NMR Center,\r Charlestown, MA 02129; School of Psychology, Bangor,\r Wales LLS7 2DG, United Kingdom; and..."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Russel A.","family":"Poldrack","sequence":"additional","affiliation":[{"name":"Department of Neurology, University of California, Davis, CA\r 95616; Veterans Administration Medical Center, Martinez,\r CA 94553; Department of Psychology, University of\r California, Berkeley, CA 94720; National Aeronautics and\r Space Administration\u2013Ames Research Center, Moffett Field, CA\r 94035; Department of Psychology, Stanford University, Stanford, CA\r 94305; Massachusetts General Hospital, NMR Center,\r Charlestown, MA 02129; School of Psychology, Bangor,\r Wales LLS7 2DG, United Kingdom; and..."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Diane","family":"Swick","sequence":"additional","affiliation":[{"name":"Department of Neurology, University of California, Davis, CA\r 95616; Veterans Administration Medical Center, Martinez,\r CA 94553; Department of Psychology, University of\r California, Berkeley, CA 94720; National Aeronautics and\r Space Administration\u2013Ames Research Center, Moffett Field, CA\r 94035; Department of Psychology, Stanford University, Stanford, CA\r 94305; Massachusetts General Hospital, NMR Center,\r Charlestown, MA 02129; School of Psychology, Bangor,\r Wales LLS7 2DG, United Kingdom; and..."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Robert D.","family":"Rafal","sequence":"additional","affiliation":[{"name":"Department of Neurology, University of California, Davis, CA\r 95616; Veterans Administration Medical Center, Martinez,\r CA 94553; Department of Psychology, University of\r California, Berkeley, CA 94720; National Aeronautics and\r Space Administration\u2013Ames Research Center, Moffett Field, CA\r 94035; Department of Psychology, Stanford University, Stanford, CA\r 94305; Massachusetts General Hospital, NMR Center,\r Charlestown, MA 02129; School of Psychology, Bangor,\r Wales LLS7 2DG, United Kingdom; and..."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"John D.
