Abstract:
Our understanding of the neural correlates of crossmodal binding in the human brain derives almost exclusively from studies of audition, vision and somatosensation. A new study by Gottfried and Dolan extends our understanding of multisensory integration by showing that facilitation of odor detection by visual cues depends on object congruency, as well as on enhanced activity in the superior temporal sulcus and a region of the orbitofrontal cortex that is adjacent to olfactory association cortex.
