Book Description
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.
The Neural Bases of Multisensory Processes
Author: Micah M. MurrayPublisher: CRC Press
ISBN: 1439812179
Category : Science
Languages : en
Pages : 800
Book Description
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.

Pages : 131
Book Description
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.
Sensation of Movement
Author: Thor GrünbaumPublisher: Routledge
ISBN: 1317238559
Category : Psychology
Languages : en
Pages : 255
Book Description
Sensation of Movement explores the role of sensation in motor control, bodily self-recognition and sense of agency. The sensation of movement is dependent on a range of information received by the brain, from signalling in the peripheral sensory organs to the establishment of higher order goals. Through the integration of neuroscientific knowledge with psychological and philosophical perspectives, this book questions whether one type of information is more relevant for the ability to sense and control movement. Addressing conscious sensations of movement, experimental designs and measures, and the possible functions of proprioceptive and kinaesthetic information in motor control and bodily cognition, the book advocates the integration of neuroscientific knowledge and philosophical perspectives. With an awareness of the diverse ideas and theories from these distinct fields, the book brings together leading researchers to bridge these divides and lay the groundwork for future research. Of interest to both students and researchers of consciousness, Sensation of Movement will be essential reading for those researching motor control, multimodal perception, bodily self-recognition, and sense of agency. It aims to encourage the integration of multiple perspectives in order to arrive at new insights into how sensation of movement can be studied scientifically.
Multisensory Control of Posture

Pages : 613
Book Description
From recent developments in the rapidly growing area of neuroscience it has become increasingly clear that a simplistic description of brain function as a broad collection of simple input-output relations is quite inadequate. Introspection already tells us that our motor behavior is guided by a complex interplay between many inputs from the outside world and from our internal "milieu," internal models of ourselves and the outside world, memory content, directed attention, volition, and so forth. Also, our motor activity normally involves more than a circumscribed group of muscles, even if we intend to move only one effector organ. For example, a reaching movement or a reorientation of a sensory organ almost invariably requires a pattern of preparatory or assisting activities in other parts of the body, like the ones that maintain the body's equilibrium. The present volume is a summary of the papers presented at the symposium "Sensory Interaction in Posture and Movement Control" that was held at Smolenice Castle near Bratislava, Slovakia, as a Satellite Symposium to the ENA Meeting 1994 in Vienna. The focus of this meeting was not only restricted to the "classical" sensory interactions such as between vestibular and visual signals, or between otolith and semicircular canal inputs. Rather, the symposium tried to consider also the interplay between perception and action, between reflexive and volitional motor acts as well as between sensory driven or self-initi ated motor acts and reafferent inputs.
Vestibular Cognition

Pages : 305
Book Description
In this volume specific cognitive sub-functions are identified and indications of how basic vestibular input contributes to each are described. The broad range of these functions is consistent with the broad spread of vestibular projections throughout the cortex. Combining vestibular signals about the head’s orientation relative to gravity with information about head position relative to the body provides sufficient information to map body position onto the ground surface and underlie the sense of spatial position. But vestibular signals are also fundamental to sensorimotor control and even to high-level bodily perception such as the sense of body ownership and the anchoring of perspective to the body. Clinical observations confirm the essential role of vestibular signals in maintaining a coherent self-representation and suggest some novel rehabilitation strategies. The chapters presented in this volume are previously published in a Special Issue of Multisensory Research, Volume 28, Issue 5-6 (2015). Contributors are: M. Barnett-Cowan, O. Blanke, J. Blouin, G.
