Multisensory Integration: Frequency Tuning of Audio-Tactile Integration

Multisensory information can be crucial, yet in many circumstances we have little, if any, awareness of the effects of multisensory inputs on what appear to be entirely unisensory perceptions. A recent study shows robust effects of auditory input on tactile frequency discriminations and that this auditory cross-sensory interference has specific tuning.

TMS of posterior parietal cortex disrupts visual tactile multisensory integration.

Functional neuroimaging studies have implicated a number of brain regions, especially the posterior parietal cortex (PPC), as being potentially important for visual-tactile multisensory integration. However, neuroimaging studies are correlational and do not prove the necessity of a region for the behavioral improvements that are the hallmark of multisensory integration. To remedy this knowledge...

Neural Substrates of Reliability-Weighted Visual-Tactile Multisensory Integration

As sensory systems deteriorate in aging or disease, the brain must relearn the appropriate weights to assign each modality during multisensory integration. Using blood-oxygen level dependent functional magnetic resonance imaging of human subjects, we tested a model for the neural mechanisms of sensory weighting, termed "weighted connections." This model holds that the connection weights between...

Spatial-frequency tuning of visual contour integration.

We examine the mechanism that subserves visual contour detection and particularly its tuning for the spatial frequency of contour components. We measured the detection of contours composed of Gabor micropatterns within a field of randomly oriented distractor elements. Distractors were randomly assigned one of two spatial frequencies, and elements lying along the contour alternated between these...

Facilitation of multisensory integration

Whenever two or more sensory inputs are highly consistent in one or more dimension(s), observers will be more likely to perceive them as a single multisensory event rather than as separate unimodal events. For audiovisual speech, but not for other noncommunicative events, participants exhibit a “unity effect,” whereby they are less sensitive to temporal asynchrony (i.e., that are more likely to...
