INTERDISCIPLINARY STUDIES OF MULTISENSORY INTEGRATION: FROM SINGLE UNITS TO PERCEPTION
The integration of information from multiple sensory sources is a ubiquitous and highlyadaptive process that can dramatically alter behavior and shape perception. NeurophysiologicalÂ studies in animal models and in human subjects have begun to reveal the combinatorial rules byÂ which neurons and networks combine this multisensory information to create a coherent perceptualÂ unity. In addition, recent work has highlighted that the development of multisensory circuits isÂ strongly shaped by early sensory experience, and has the capacity for significant plasticity. MostÂ recently, studies have begun to focus on the plastic potential of adult multisensory processes.Â This work has found that significant plasticity can be engendered in adult multisensory systems,Â but only by coupling changes in the statistical relations of the combined stimuli withÂ reinforcement. Such findings have significant implications for our understanding of basicÂ integrative processes and have shed important light in bridging between neuronal and perceptualÂ levels of analysis.
