Multisensory integration: resolving sensory ambiguities to build novel representations

Multimodal integration: Resolving sensory ambiguities to build novel representations

Summary—Multisensory integration plays several important roles in the nervous system. One is to combine information from multiple complementary cues to improve stimulus detection and discrimination. Another is to resolve peripheral sensory ambiguities and create novel internal representations that do not exist at the level of individual sensors. Here we focus on how ambiguities inherent in vest...

Multisensory integration, sensory substitution and visual rehabilitation.

Sensory substitution has advanced remarkably over the past 35 years since first introduced to the scientific literature by Paul Bach-y-Rita. In this issue dedicated to his memory, we describe a collection of reviews that assess the current state of neuroscience research on sensory substitution, visual rehabilitation, and multisensory processes.

Resolving Motion Ambiguities

D. Geiger* Courant Institute, NYU Mercer Street New York, NY 10012 We address the problem of optical flow reconstruction and in particular the problem of resolving ambiguities near edges. They occur due to (i) the aperture problem and (ii) the occlusion problem, where pixels on both sides of an intensity edge are assigned the same velocity estimates (and confidence). However, these measurements...

Development of Multisensory Integration: Transforming Sensory Input into Motor Output

By pooling and integrating signals from different sensory channels, specialized populations of ‘‘multisensory’’ neurons not only help to maximize the brain’s ability to detect and identify external events, but also help to initiate reactions to them. Although multisensory neurons are found in many areas of the brain, those in the midbrain (i.e., superior colliculus, SC) have been studied most e...
