Auditory and Visual Contributions to Multisensory Integration
Multisensory integration, or the merging of information from multiple sensory modalities, is important for many everyday tasks. One methodology used for examining this process is the Sound Induced Flash Illusion (SIFI), which presents participants with a number of flashes and either the same number of beeps (congruent) or a different number of beeps (incongruent), and requires the participant t...
متن کاملIntegration of Visual Information in Auditory Cortex Promotes Auditory Scene Analysis through Multisensory Binding
How and where in the brain audio-visual signals are bound to create multimodal objects remains unknown. One hypothesis is that temporal coherence between dynamic multisensory signals provides a mechanism for binding stimulus features across sensory modalities. Here, we report that when the luminance of a visual stimulus is temporally coherent with the amplitude fluctuations of one sound in a mi...
متن کاملContinuous flash suppression modulates cortical activity in early visual cortex.
A salient visual stimulus can be rendered invisible by presenting it to one eye while flashing a mask to the other eye. This procedure, called continuous flash suppression (CFS), has been proposed as an ideal way of studying awareness as it can make a stimulus imperceptible for extended periods of time. Previous studies have reported robust suppression of cortical activity in higher visual area...
متن کاملMultisensory Integration: Vision Boosts Information through Suppression in Auditory Cortex
Signals from non-primary modalities can influence neural activity in 'unimodal' sensory areas of the neocortex, but whether this 'extra-modal' influence has any relevant consequences for neural coding has been unclear. Recent findings show that vision enhances the information content of neural signals in auditory cortex, but in a counter-intuitive fashion.
