Audio-visual Information for Speech-hand Gestures. How does audio-visual information influence human movement and communication? We will investigate whether speech and hand gestures involve shared information about the timing of rhythmic movements. Using dynamical systems theory and brain imaging techniques, we will study rhythms that emerge during simultaneous speaking and finger tapping in both stutterers and non-stutterers, and in left-handers and right-handers. The communicative interaction ....Audio-visual Information for Speech-hand Gestures. How does audio-visual information influence human movement and communication? We will investigate whether speech and hand gestures involve shared information about the timing of rhythmic movements. Using dynamical systems theory and brain imaging techniques, we will study rhythms that emerge during simultaneous speaking and finger tapping in both stutterers and non-stutterers, and in left-handers and right-handers. The communicative interaction of two persons performing speech-hand gestures will be examined. Results will clarify how brain asymmetry affects gestural coordination in stutterers, how stuttering can be treated, and the hypothesis that speech and language evolved from a communication system based on hand gestures.

How does visual information and attention determine the control and coordination of locomotion? Using large-screen projection of computer graphics and immersive virtual reality, we will examine the influence of visual information on driver training, gait in the elderly, cardiorespiratory control, and the attentional interference of mobile phones on driving. Experiments will be based on principles from dynamical and complex systems theory and will inform the design of innovative algorithms for autonomous mobile robots. Expected outcomes include improved road safety, new methods for the rehabilitation of those with gait disorders, and a deeper understanding of the physiological response to virtual exercise.Read moreRead less
Competing demands on the axial muscles: Effects, consequences, compensations and mechanisms. Back and neck pain are major health issues and are associated with considerable cost to society and an individual's quality of life. A major issue is to identify factors that increase the chance of developing pain. This project will investigate a novel and innovative possibility; that competition between the many functions of the trunk muscles may increase the possibility for injury. We will study how th ....Competing demands on the axial muscles: Effects, consequences, compensations and mechanisms. Back and neck pain are major health issues and are associated with considerable cost to society and an individual's quality of life. A major issue is to identify factors that increase the chance of developing pain. This project will investigate a novel and innovative possibility; that competition between the many functions of the trunk muscles may increase the possibility for injury. We will study how the nervous system coordinates functions as diverse and movement of the spine, breathing, and control of head and eye movement. A key issue will be to identify whether situations arise in which control of the spine is compromised, potentially leading to increased risk of pain and injury. Such data can aid prevention and rehabilitation.Read moreRead less
Urinary continence and incontinence in men: New insight through new technologies. Healthy ageing in men is largely overlooked. Disorders of continence are surprisingly common with increasing age, and are socially debilitating. To understand changes in continence and address healthy ageing it is first necessary to gain an understanding of continence mechanisms in healthy men. Continence in women has received wide attention, but anatomy and function differ, as do the challenges throughout life (ch ....Urinary continence and incontinence in men: New insight through new technologies. Healthy ageing in men is largely overlooked. Disorders of continence are surprisingly common with increasing age, and are socially debilitating. To understand changes in continence and address healthy ageing it is first necessary to gain an understanding of continence mechanisms in healthy men. Continence in women has received wide attention, but anatomy and function differ, as do the challenges throughout life (childbirth vs. prostate disease). Using novel methods we will test a new hypothesis of male continence with the goal to provide new physiological discoveries, new methods, and baseline data upon which strategies to enhance healthy ageing and reduce the economic burden of disorders of continence can be developed and refined.

Revealing the beneficial effects of acoustic stimulation on the human brain. This project aims to provide greater understanding of the neural mechanisms by which initiation of motor responses can be improved by unexpected auditory stimulation. Initiating motor actions appears natural and effortless, but is underpinned by complex neural mechanisms that are not well understood.

This project aims to provide greater understanding of the neural mechanisms by which initiation of motor responses can be improved by unexpected auditory stimulation. Initiating motor actions appears natural and effortless, but is underpinned by complex neural mechanisms that are not well understood. Using novel brain stimulation techniques, the project aims to assess the potential for properly timed strong sensory stimulation during movement preparation to induce neural plasticity and motor learning. This knowledge would have important implications across a number of fields, including neuroscience, sports science, and applied ergonomics.Read moreRead less

Summary
The predictive brain and control of anticipatory actions. The ability to predict events in a dynamic environment is an important skill for survival as it can guide our actions when time pressures are severe. How predictions come about to guide our actions is not clear and project results will have great theoretical significance to understand how we generate them.
The influence of resistance training upon movement control in the elderly. The primary aim of this applied research project is to investigate the impact of resistance training in the elderly. We will assess the responses to training that occur in the elderly, and determine the time course and persistence of adaptation. It is anticipated that the knowledge derived will be applied by clinicians and health practitioners in the design of resistance training programmes for the elderly, and thereby en ....The influence of resistance training upon movement control in the elderly.
