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.

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.

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 monograph has been written for clinicians who are involved in the management of the dizzy patient and for scientists with a particular interest in the multi-sensorimotor mechan isms that subserve spatial orientation, motion perception, and ocular motor and postural con trol. Special emphasis has been put on making the correct diagnosis, and detailed recommendations have been given for specific treatments. The second edition has resulted in an almost completely new book due to the dramatic expansion in the 1990s of our understanding of vestibular function and dis orders. A few rele vant examples include the novel concept of canalolithiasis, as opposed to cupulolithiasis, both of which are established causes of typical posterior and horizontal canal benign paroxysmal positioning vertigo; familial episodic ataxia land II have been identified as inherited chan nelopathies; otolithic syndromes were recognized as a variety separate from semicircular canal syndromes; several new central vestibular syndromes have been described, localized, and attributed to vestibular pathways and centres; a new classification based on the three major planes of action of the vestibulo-ocular reflex is available for central vestibular syn dromes; and the mystery of the location and function of the multisensory vestibular cortex is slowly being unravelled. This book differs from other clinical textbooks in that it is not divided into two parts: anatomy and physiology, on the one hand, and disorders, on the other.

A comprehensive examination of head-direction signals and their importance in explaining orienting and navigation behaviors. Head direction cells—neurons that fire only when an animal orients its head in a certain direction—are found in several different brain areas, with different neurons selective for different head orientations; they are influenced by landmarks as well as motor and vestibular information concerning how the head moves through space. These properties suggest that head direction cells play an important role in determining orientation in space and in navigation. Moreover, the prominence, strength, and clarity of head direction signals indicate their importance over the course of evolution and suggest that they can serve as a vital key for understanding brain function. This book presents the latest findings on head direction cells in a comprehensive treatment that will be a valuable reference for students and researchers in the cognitive sciences, neuroscience, computational science, and robotics. The book begins by presenting head direction cell properties and an anatomical framework of the head direction system. It then looks at the types of sensory and motor information that control head direction cell firing, covering topics including the integration of diverse signals; the relationship between head direction cell activity and an animal's spatial behavior; and spatial and directional orientation in nonhuman primates and humans. The book concludes with a tutorial demonstrating the implementation of the continuous attractor network, a computational model of head direction cells, and an application of this approach for a navigational system for mobile robots.
