In recent years there has been a dramatic progress in understanding how stimuli from different sensory modalities are integrated among each other. Multisensory integration results in a unitary representation of the world that strongly characterizes perception and cognition in humans. Knowledge about multi sensory integration has research techniques and approaches, including neurophysiology, experimental psychology, neuropsychology, neuroimaging, and computational modelling. This special issue aims at presenting an up-to-date integrative overview of the physiological, psychological, developmental, and functional processes associated with multisensory integration. The proposed collection of papers is organized thematically into sections, each featuring a state-of-the-art review of key themes in multisensory research, from more approaches in the animal, to the study of multisensory perception and cognition in humans. Specifically, this special issue will consider: The physiological mechanisms of multisensory processing in cortical and subcortical brain structures of model animal species, (rat, cat, and monkey); current biologically inspired computational modelling of multisensory integration; evidence about the multisensory contributions to perception in humans, as highlighted by psychophysical and neuropsychological evidence; the neural basis of multisensory processing in the human brain uncovered by recent neuroimaging techniques, including EEG, PET, fMRI; the consequences of the breakdown of normal sensory integration as shown by studies with techniques of brain stimulation in humans; developmental processes of multisensory perception in humans and the constrains for the emergence of multisensory processes in relation to sensory experience; the issue of crossmodal neuroplasticity concerning behavioral and neural changes following sensory deprivation. The challenge of this Research Topic is to provide an interdisciplinary context allowing to understand the basic principles of multisensory integration in humans and the key issues that this fascinating field of study rises for future research.

This book is concerned with sensory cue integration both within and between sensory modalities, and focuses on the emerging way of thinking about cue combination in terms of uncertainty. These probabilistic approaches derive from the realization that our sensors are noisy and moreover are often affected by ambiguity. For example, mechanoreceptor outputs are variable and they cannot distinguish if a perceived force is caused by the weight of an object or by force we are producing ourselves. The probabilistic approaches elaborated in this book aim at formalizing the uncertainty of cues. They describe cue combination as the nervous system's attempt to minimize uncertainty in its estimates and to choose successful actions. Some computational approaches described in the chapters of this book are concerned with the application of such statistical ideas to real-world cue-combination problems. Others ask how uncertainty may be represented in the nervous system and used for cue combination. Importantly, across behavioral, electrophysiological and theoretical approaches, Bayesian statistics is emerging as a common language in which cue-combination problems can be expressed.

To derive the precise estimates of self-motion necessary to perform mobility-related tasks like walking and driving, humans integrate information about their movement from across their sensory systems (e.g. visual, auditory, proprioceptive, vestibular). However, recent evidence suggests that the way in which multiple sensory inputs are integrated by the adult brain changes with age. The objective of this thesis was to consider, for the first time, whether age-related changes in multisensory integration are observed in the context of self-motion perception. Two research approaches were used. First, I used a simple, simulated driving task to provide visual cues to self-motion and to manipulate the availability of auditory and/or vestibular cues to self-motion (i.e., unisensory versus multisensory conditions). The results revealed that relative to younger adults, older adults generally demonstrate greater differences in performance between multisensory and unisensory conditions. However, the driving task could not disentangle the effects of age-related differences in real-world driving experience from age-related differences in sensory integrative mechanisms. Second, I used an established and highly controlled psychophysical heading perception task to evaluate whether, like younger adults, older adults integrate visual and vestibular cues to self-motion in a statistically optimal fashion. I considered conditions where each of the two cues was presented alone, in combination and congruent, or in combination but indicating conflicting heading angles. Results showed that while older adults did demonstrate optimal integration during congruent conditions, they were comparatively less tolerant to spatial conflicts between the visual and vestibular inputs. Overall, these results may have important implications for the way that older adults perform mobility-related tasks under various perceptual and environmental conditions.

It has become accepted in the neuroscience community that perception and performance are quintessentially multisensory by nature. Using the full palette of modern brain imaging and neuroscience methods, The Neural Bases of Multisensory Processes details current understanding in the neural bases for these phenomena as studied across species, stages of development, and clinical statuses. Organized thematically into nine sub-sections, the book is a collection of contributions by leading scientists in the field. Chapters build generally from basic to applied, allowing readers to ascertain how fundamental science informs the clinical and applied sciences. Topics discussed include: Anatomy, essential for understanding the neural substrates of multisensory processing Neurophysiological bases and how multisensory stimuli can dramatically change the encoding processes for sensory information Combinatorial principles and modeling, focusing on efforts to gain a better mechanistic handle on multisensory operations and their network dynamics Development and plasticity Clinical manifestations and how perception and action are affected by altered sensory experience Attention and spatial representations The last sections of the book focus on naturalistic multisensory processes in three separate contexts: motion signals, multisensory contributions to the perception and generation of communication signals, and how the perception of flavor is generated. The text provides a solid introduction for newcomers and a strong overview of the current state of the field for experts.

We perceive and understand our environment using many sensory systems-vision, touch, hearing, taste, smell, and proprioception. These multiple sensory modalities give us complementary sources of information about the environment. This book explores how we develop the ability to integrate our senses.

The major reference work for a rapidly advancing field synthesizes central themes, reports on current findings, and offers a blueprint for future research. Scientists' attempts to understand the physiology underlying our apprehension of the physical world was long dominated by a focus on the individual senses. The 1980s saw the beginning of systematic efforts to examine interactions among different sensory modalities at the level of the single neuron. And by the end of the 1990s, a recognizable and multidisciplinary field of "multisensory processes" had emerged. More recently, studies involving both human and nonhuman subjects have focused on relationships among multisensory neuronal ensembles and their behavioral, perceptual, and cognitive correlates. The New Handbook of Multisensory Processing synthesizes the central themes in this rapidly developing area, reports on current findings, and offers a blueprint for future research. The contributions, all of them written for this volume by leading experts, reflect the evolution and current state of the field. This handbook does more than simply review the field. Each of the volume's eleven sections broadly surveys a major topic, and each begins with a substantive and thought-provoking commentary by the section editor that identifies the major issues being explored, describes their treatment in the chapters that follow, and sets these findings within the context of the existing body of knowledge. Together, the commentaries and chapters provide an invaluable guide to areas of general agreement, unresolved issues, and topics that remain to be explored in this fast-moving field.
