How brain oscillations influence our behaviour. This project aims to reveal how sudden, intense stimuli impair or facilitate concurrent actions. Startling sounds can disrupt the execution of movements and distract attention from vital events in the environment, with potential disastrous consequences when handling complex equipment such as airplanes, cars and trucks, or surgical instruments. This project will combine classic experimental and novel neuro-modulatory techniques with the measurement ....How brain oscillations influence our behaviour. This project aims to reveal how sudden, intense stimuli impair or facilitate concurrent actions. Startling sounds can disrupt the execution of movements and distract attention from vital events in the environment, with potential disastrous consequences when handling complex equipment such as airplanes, cars and trucks, or surgical instruments. This project will combine classic experimental and novel neuro-modulatory techniques with the measurement of oscillatory brain activity. Expect outcomes will inform theories of cognitive function and the design of interventions to reduce the negative effects of sudden, distracting events.Read moreRead less
Structural and neural determinants of stress and strain in human muscle.

This project aims to further our understanding of the biomechanical stress and strains experienced by contracting human muscles. Using innovative imaging techniques such as microendoscopy and supersonic shear imaging, we expect to generate new significant evidence on the structural and neural factors that lead to areas of high stress in human muscles. Outcomes of this project include not only a new understanding of muscle design on multi-scale level, but also of muscle function and adaptation. This should provide significant benefits in better predicting muscle injury and prescribing safe exercise, knowledge that would benefit biomechanical engineers and sport and exercise professionals.Read moreRead less
Experimental and computational assessment of the mechanical, musculo-skeletal and neuromuscular contributions to rhythmic multi-joint arm movements. The human body is a complex mechanical system that is controlled by a vast neural network comprising many millions of connections. To date, realistic descriptions of the interactions between these neuro-mechanical features have proved elusive.

The human body is a complex mechanical system that is controlled by a vast neural network comprising many millions of connections. To date, realistic descriptions of the interactions between these neuro-mechanical features have proved elusive. This project seeks to develop a mathematical model that accurately describes the essential features of the control system for human movement, and yet is simple enough to inform the design of artificial devices to generate or assist movement. The knowledge derived should improve mechanical and neural prosthetic systems, and guide rehabilitation protocols. The work will ultimately provide a considerable benefit to the community by reducing the social cost of a range of movement disorders.Read moreRead less
An inverse control approach to resolving the neural basis of spatial and muscular dependencies in coordinated multi-limb movements. Each year 48,000 Australians suffer from stroke with many survivors left with problems that limit limb function. With reduced duration of hospital care, the opportunities for retraining in the period immediate following stroke are rapidly diminishing.

Each year 48,000 Australians suffer from stroke with many survivors left with problems that limit limb function. With reduced duration of hospital care, the opportunities for retraining in the period immediate following stroke are rapidly diminishing. Effective and efficient strategies of rehabilitation that will maximise the level of recovery following stroke will result in benefits expressed in terms of enhanced quality of life and functional life-span, as well as significantly reduced costs of health care. In understanding the fundamental principles underlying the stability and adaptability of movement coordination, this research is likely to make a significant contribution to the design of programs for movement rehabilitation.Read moreRead less
Learning control and computational models of human motor systems.

The results will lead to improvements in smart industrial automation and the development of more effective rehabilitation stategies.
Interceptive Action: Performance, Neuromotor Control and Learning. Natural, everyday environments are dynamic. People, animals and other objects move around and human behaviour must be geared to these motions: people must anticipate where things are going and when they will get there so that undesirable collisions and contacts can be avoided and desirable ones achieved. This project investigates basic modes of interacting with dynamic environments - intercepting and evading objects in motion. T ....Interceptive Action: Performance, Neuromotor Control and Learning. Natural, everyday environments are dynamic. People, animals and other objects move around and human behaviour must be geared to these motions: people must anticipate where things are going and when they will get there so that undesirable collisions and contacts can be avoided and desirable ones achieved. This project investigates basic modes of interacting with dynamic environments - intercepting and evading objects in motion. The aim is to extend our understanding of the principles, control mechanisms and brain structures involved. Such understanding has the potential to contribute to areas such as road safety, autonomous robotics, sports training and neurological rehabilitation.Read moreRead less
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. 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

Facilitatory and inhibitory mechanisms during interlimb coordination in young and older adults. The project seeks to understand how people coordinate their limbs and the factors which limit and enhance this capacity. This is of critical importance because coordination is a dominant deficit in aging and in patients suffering brain insult and neurodegenerative diseases. Disruption of this capacity compromises individual work productivity, mobility and independence. Proficient motor functioning is ....Facilitatory and inhibitory mechanisms during interlimb coordination in young and older adults. The project seeks to understand how people coordinate their limbs and the factors which limit and enhance this capacity. This is of critical importance because coordination is a dominant deficit in aging and in patients suffering brain insult and neurodegenerative diseases. Disruption of this capacity compromises individual work productivity, mobility and independence. Proficient motor functioning is an important lifestyle factor as humans age and deficits in coordinated muscle activity will increase the risk of falls which are the leading cause of injury in elderly adults. Identification of changes in brain processes involved in interlimb coordination will allow for the development of strategies to improve motor functions in the aged.Read moreRead less
Determining the neural mechanisms of visual stimuli and motor responses. This project aims to determine how we select actions to visual cues rapidly, unconsciously and automatically. Learning associations between visual stimuli and motor responses is part of normal development and continues throughout life.

This project aims to determine how we select actions to visual cues rapidly, unconsciously and automatically. Learning associations between visual stimuli and motor responses is part of normal development and continues throughout life. Rapid deployment of these actions is often critical for safety yet we have limited knowledge of how the human brain does this. This project will use neuroimaging tools to characterise the spatial and temporal neural architecture underlying these processes and determine how the dorsal and ventral streams of visual processing, specialised for motor control and recognition respectively, interact in vision-based actions as these actions become learned.Outcomes will provide new frameworks for driving improvement in any domain in which goal-directed actions depend on the rapid processing of visual information, including human-machine interfaces for defence, economic development, education, health, science and technology.Read moreRead less
