Let's face it: it's a cortical networkAlumit Ishai
Institute of Neuroradiology, University of Zurich, Winterthurerstrasse 190, 8057 Zurich, Switzerland
Neuroimage 40:415-9. 2008..A model for face perception is proposed, in which the flow of information through the network is shaped by cognitive demands...
Comparison of fMRI activation as measured with gradient- and spin-echo EPI during visual perceptionConny F Schmidt
Institute for Biomedical Engineering, University of Zurich and Swiss Federal Institute of Technology, Switzerland
Neuroimage 26:852-9. 2005..Our data indicate that optimized GE sequences that reduce susceptibility artefacts are sufficient to detect activation in regions such as the orbitofrontal cortex...
Seeing faces and objects with the "mind's eye"Alumit Ishai
Institute of Neuroradiology, University of Zurich, Switzerland
Arch Ital Biol 148:1-9. 2010..The relation of these findings to other cognitive functions is discussed, as well as their clinical implications for patients with impaired states of conscious awareness...
Perception, memory and aesthetics of indeterminate artAlumit Ishai
University of Zurich, Winterthurerstrasse 190, 8057 Zurich, Switzerland
Brain Res Bull 73:319-24. 2007..Indeterminate art works therefore comprise a rich set of stimuli with which the neural correlates of visual perception can be investigated...
Recognition memory of newly learned facesAlumit Ishai
Institute of Neuroradiology, University of Zurich, Winterthurerstrasse 190, 8057 Zurich, Switzerland
Brain Res Bull 71:167-73. 2006....
Effective connectivity within the distributed cortical network for face perceptionScott L Fairhall
Institute of Neuroradiology, University of Zurich, Winterthurerstrasse 190, 8057 Zurich, Switzerland
Cereb Cortex 17:2400-6. 2007..Our results demonstrate content-specific dynamic alterations in the functional coupling between visual-limbic and visual-prefrontal face-responsive pathways...
Neural correlates of object indeterminacy in art compositionsScott L Fairhall
Institute of Neuroradiology, University of Zurich, Winterthurerstrasse 190, 8057 Zurich, Switzerland
Conscious Cogn 17:923-32. 2008..Our results suggest that perception of familiar content in art works is mediated by object recognition, memory recall and mental imagery, cognitive processes that evoke activation within a distributed cortical network...
Temporal dynamics of face repetition suppressionAlumit Ishai
Institute of Neuroradiology, University of Zurich, Winterthurerstrasse 190, 8057 Zurich, Switzerland
Brain Res Bull 70:289-95. 2006..Our data indicate that valence enhancement and context effects can be detected in extrastriate visual cortex within 250 ms and that these processes likely reflect feedback from other regions...
Sex, beauty and the orbitofrontal cortexAlumit Ishai
Institute of Neuroradiology, University of Zurich, Winterthurerstrasse 190, 8057, Zurich, Switzerland
Int J Psychophysiol 63:181-5. 2007..These findings suggest that the OFC represents the value of salient sexually-relevant faces, irrespective of their reproductive fitness...
Face perception is mediated by a distributed cortical networkAlumit Ishai
Institute of Neuroradiology, University of Zurich, Winterthurerstrasse 190, 8057 Zurich, Switzerland
Brain Res Bull 67:87-93. 2005..These results indicate that a mere percept of a face is sufficient to localize activation within the distributed cortical network that mediates the visual analysis of facial identity and expression...
Face perception is modulated by sexual preferenceFelicitas Kranz
Institute of Neuroradiology, University of Zurich, Zurich, Switzerland; Institute for Biomedical Engineering, Swiss Federal Institute of Technology, Zurich, Switzerland
Curr Biol 16:63-8. 2006..Our findings suggest that sexual preference modulates face-evoked activation in the reward circuitry...
Recognition memory is modulated by visual similarityElena Yago
Institute of Neuroradiology, University of Zurich, Winterthurerstrasse 190, 8057 Zurich, Switzerland
Neuroimage 31:807-17. 2006..Our findings suggest that recognition memory is mediated by classification of novel exemplars as a match or a mismatch, based on their visual similarity to familiar prototypes...
Repetition suppression of faces is modulated by emotionAlumit Ishai
Laboratory of Brain and Cognition, National Institute of Mental Health, National Institutes of Health, Bethesda, MD 20892, USA
Proc Natl Acad Sci U S A 101:9827-32. 2004..Our findings demonstrate a three-way interaction between emotional valence, repetition, and task relevance and suggest that repetition suppression is influenced by high-level cognitive processes in the human brain...
Famous faces activate contextual associations in the parahippocampal cortexMoshe Bar
Martinos Center at Massachusetts General Hospital, Harvard Medical School, Charlestown, MA 02129, USA
Cereb Cortex 18:1233-8. 2008..Taken collectively, these findings indicate that the PHC should be regarded as mediating contextual associations in general and not necessarily spatial or episodic information...
Where bottom-up meets top-down: neuronal interactions during perception and imageryAndrea Mechelli
Wellcome Department of Imaging Neuroscience, Institute of Neurology, 12 Queen Square, London, WC1N 3BG, UK
Cereb Cortex 14:1256-65. 2004..Additionally non-selective, top-down processes, originating in superior parietal areas, contribute to the generation of mental images, regardless of their content, and their maintenance in the 'mind's eye'...
Visual imagery of famous faces: effects of memory and attention revealed by fMRIAlumit Ishai
Laboratory of Brain and Cognition, NIMH, National Institutes of Health, Bethesda, Maryland 20892-1366, USA
Neuroimage 17:1729-41. 2002..g., eyes, lips, or nose) resulted in increased activation in the right IPS and right IFG. Our results suggest differential effects of memory and attention during the generation and maintenance of mental images of faces...
