Integration 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 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.
متن کاملAuditory 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 and segregation in auditory scene analysis.
Assessment of the neural correlates of auditory scene analysis, using an index of sound change detection that does not require the listener to attend to the sounds [a component of event-related brain potentials called the mismatch negativity (MMN)], has previously demonstrated that segregation processes can occur without attention focused on the sounds and that within-stream contextual factors ...
متن کاملAuditory-driven phase reset in visual cortex: Human electrocorticography reveals mechanisms of early multisensory integration
Findings in animal models demonstrate that activity within hierarchically early sensory cortical regions can be modulated by cross-sensory inputs through resetting of the phase of ongoing intrinsic neural oscillations. Here, subdural recordings evaluated whether phase resetting by auditory inputs would impact multisensory integration processes in human visual cortex. Results clearly showed audi...
