Multisensory visual-auditory object recognition in humans: a high-density electrical mapping study.
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...
متن کاملMultisensory auditory-visual interactions during early sensory processing in humans: a high-density electrical mapping study.
Integration of information from multiple senses is fundamental to perception and cognition, but when and where this is accomplished in the brain is not well understood. This study examined the timing and topography of cortical auditory-visual interactions using high-density event-related potentials (ERPs) during a simple reaction-time (RT) task. Visual and auditory stimuli were presented alone ...
متن کاملMultisensory auditory-somatosensory interactions in early cortical processing revealed by high-density electrical mapping.
We investigated the time-course and scalp topography of multisensory interactions between simultaneous auditory and somatosensory stimulation in humans. Event-related potentials (ERPs) were recorded from 64 scalp electrodes while subjects were presented with auditory-alone stimulation (1000-Hz tones), somatosensory-alone stimulation (median nerve electrical pulses), and simultaneous auditory-so...
متن کاملMultisensory processing in children with autism: high-density electrical mapping of auditory-somatosensory integration.
Successful integration of signals from the various sensory systems is crucial for normal sensory-perceptual functioning, allowing for the perception of coherent objects rather than a disconnected cluster of fragmented features. Several prominent theories of autism suggest that automatic integration is impaired in this population, but there have been few empirical tests of this thesis. A standar...
متن کاملMultisensory processing of naturalistic objects in motion: a high-density electrical mapping and source estimation study.
In everyday life, we continuously and effortlessly integrate the multiple sensory inputs from objects in motion. For instance, the sound and the visual percept of vehicles in traffic provide us with complementary information about the location and motion of vehicles. Here, we used high-density electrical mapping and local auto-regressive average (LAURA) source estimation to study the integratio...
