Modulation of human extrastriate visual processing by audio-visual attention

Abstract: IntroductionThe orientation of attention within the specificsensory modality is known to evoke enhancedactivity in the modality-specific and/or stimulusfeature-specific region in the human brain by usinghemodynamic functional brain imaging methods(fMRI, PET) [1-4] and electrophysiological methods(EEG, MEG) [5-8]. Particularly, selective attentionto specific stimulus features like color, form,movement and face in the visual modalityselectively modulates the regional cerebral blood...
