How do past actions and rewards bias goal directed movement? This project aims to identify how different aspects of our past experience affect the accuracy of movements, and study the underlying brain mechanisms. This project will use timing methods and brain recordings to test how the history of movements we have executed in the past, and the rewards associated with those movements, interact to affect subsequent movement execution. The project should advance basic understanding of how the human ....How do past actions and rewards bias goal directed movement?

This project will use timing methods and brain recordings to test how the history of movements we have executed in the past, and the rewards associated with those movements, interact to affect subsequent movement execution. The project should advance basic understanding of how the human brain controls movement, and provide theoretical foundations needed to improve the design of human-machine interfaces, and training approaches in industry, rehabilitation and sport.Read moreRead less
The implications of resistance training for the control of movement. Resistance training (or weight lifting) is an essential element of comprehensive rehabilitation programs in a wide range of clinical settings. However, because we know little about how the organization of the nervous system is affected by training with high loads, the consequences of resistance training for our ability to control functional movements are unclear. The ultimate goal of this research is to generate basic knowledge ....The implications of resistance training for the control of movement. Resistance training (or weight lifting) is an essential element of comprehensive rehabilitation programs in a wide range of clinical settings. However, because we know little about how the organization of the nervous system is affected by training with high loads, the consequences of resistance training for our ability to control functional movements are unclear. The ultimate goal of this research is to generate basic knowledge about the impact of resistance training on nervous system function. The research will lead to the design of injury prevention and rehabilitation programs that are maximally effective, and provide a genuine benefit to the community.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 d ....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
A common sub-cortical system for human eye and limb control. This project aims to discover how the human brain controls reaching movements via structures and control mechanisms used for rapid eye movements, and for prey capture by lower vertebrates such as fish. Fast and accurate visually-guided movement was crucial for survival long before animals evolved a cerebral cortex, suggesting that basic control systems may be conserved across species. The notion that primitive sub-cortical systems can ....A common sub-cortical system for human eye and limb control. This project aims to discover how the human brain controls reaching movements via structures and control mechanisms used for rapid eye movements, and for prey capture by lower vertebrates such as fish. Fast and accurate visually-guided movement was crucial for survival long before animals evolved a cerebral cortex, suggesting that basic control systems may be conserved across species. The notion that primitive sub-cortical systems can control complex, human limb movements challenges conventional thinking about movement-related brain activity, and has important implications for the design of human-machine interfaces and training protocols in rehabilitation, industry and sport.Read moreRead less
Dynamics of Locomotion: Visualisation in skill acquisition & rehabilitation. 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 comp ....Dynamics of Locomotion: Visualisation in skill acquisition & rehabilitation. 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
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.

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
