简介
Multisensory object-recognition processes were investigated by examining the combined influence of visual and auditory inputs upon object identification — in this case, pictures and vocalizations of animals. Behaviorally, subjects were significantly faster and more accurate at identifying targets when the picture and vocalization were matched (i.e. from the same animal), than when the target was represented in only one sensory modality. This behavioral enhancement was accompanied by a modulation of the evoked potential in the latency range and general topographic region of the visual evoked N1 component, which is associated with early feature processing in the ventral visual stream. High-density topographic mapping and dipole modeling of this multisensory effect were consistent with generators in lateral occipito-temporal cortices, suggesting that auditory inputs were modulating processing in regions …
