This research may lead to the design of new therapeutics, diagnostics and applications that will benefit the Australian community, and will provide excellent training of researchers in skills required for employment in the biotechnology and pharmaceutical fields.Read moreRead less
Identifying the basis for perceptual stability and perceptual omission during saccadic eye movements. The ability to explore the world via eye movements is an important feature of visual capabilities. This project will establish how the brain maintains the perception of a stable and stationary world despite the several eye movements made each second. This knowledge will fill a conspicuous gap in the understanding of the human visual system.

Electrical stimulation of nerve fibres is an emerging physiological technique with great promise towards rehabilitation. The field lacks techniques for detailed, focal application of stimuli to recruit specific fibres for fine muscle control or conveying useful neurosensory information. The investigator has developed microtechnology for delivering stimuli to 100 sites, conceivably facilitating recruitment of specific fibres within a given bundle. Effects of muscle stimulation are readily measured and shall be used to model and refine techniques for generic high-resolution fibre recruitment. Benefits include, improved muscle control in functional electrical stimulation, sensory perception for amputees and patterned vision from optic nerve stimulation.Read moreRead less
Large-scale Parallelization of Neural Stimulation in a Visual Prosthesis. Over time, engineers have been able to treat a large number of disorders through new technologies. For example, the deaf can now hear again through cochlear implants. Similar efforts to provide vision to the blind, however, have met with difficulties owing to the high quantities of sites that must be stimulated to provide 'useful' vision. This study addresses the important issues relating to the delivery of large quantitie ....Large-scale Parallelization of Neural Stimulation in a Visual Prosthesis. Over time, engineers have been able to treat a large number of disorders through new technologies. For example, the deaf can now hear again through cochlear implants. Similar efforts to provide vision to the blind, however, have met with difficulties owing to the high quantities of sites that must be stimulated to provide 'useful' vision. This study addresses the important issues relating to the delivery of large quantities of electrical stimulations to surviving nerves in the eyes of blind patients in an effort to devise a beneficial visual prosthesis or 'bionic eye'. The outcomes of this study could substantially enhance Australia's already prominent reputation in neurostimulation and provide much needed treatments to vision disorders.Read moreRead less
Radiolabelled MMP binding agents for the identification, quantification, and targeting of MMPs in central nervous system (CNS) disorders and tumours. Cancer and diseases of the central nervous system (CNS) represent two of the major health challenges facing Australia because of the aging population.

Cancer and diseases of the central nervous system (CNS) represent two of the major health challenges facing Australia because of the aging population. In order to address these challenges we need to develop methods for identifying tumours and CNS diseases using non-invasive technologies and at an early stage so that treatments can be applied when they are most likely to work. In this project, we are developing new radiolabelled compounds that will enable the imaging of tumours, tumour metastases and CNS diseases states.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

INVESTIGATION OF A BRAIN RHYTHM. Elucidation of brain function remains a frontier for human discovery. To date, research has largely focussed on brain connectivity with major advances in knowledge of input/output function of brain regions. Yet, there remains little understanding of higher order processes that underlie functions such as mood states and consciousness. Investigation of brain rhythms represent a step to unravelling such processes, as rhythms both act as autonomous clocks and generat ....INVESTIGATION OF A BRAIN RHYTHM. Elucidation of brain function remains a frontier for human discovery. To date, research has largely focussed on brain connectivity with major advances in knowledge of input/output function of brain regions. Yet, there remains little understanding of higher order processes that underlie functions such as mood states and consciousness. Investigation of brain rhythms represent a step to unravelling such processes, as rhythms both act as autonomous clocks and generate synchronised neuronal activity. This project aims to investigate mechanisms underlying a specific class of brain rhythm implicated in control of mood states. Positive outcomes from this basic research may lead to better drug therapies for controlling specific mental disorders.Read moreRead less
Calcium Signalling and Sequestration at Vertebrate Motor-Nerve Terminals. A fundamental process at Synapses is the release of transmitter from nerve terminals due to the initiation of calcium signalling in the temrinals by impulses. This calcium signalling must be terminated by sequestering processes. The aim of this project is to identify these processes in a vertebrate motor-nerve terminal and to determine the means by which calcium signals the changes in efficacy of transmitter release during ....Calcium Signalling and Sequestration at Vertebrate Motor-Nerve Terminals. A fundamental process at Synapses is the release of transmitter from nerve terminals due to the initiation of calcium signalling in the temrinals by impulses. This calcium signalling must be terminated by sequestering processes. The aim of this project is to identify these processes in a vertebrate motor-nerve terminal and to determine the means by which calcium signals the changes in efficacy of transmitter release during trains of impulses. This work will give a complete description of calcium signalling in a vertebrate nerve terminal and provide the basis for ameliorating failures in transmission from nerve to muscle.Read moreRead less
Structure and function of a new class of multi-zinc finger (MZF) transcriptional regulators. An understanding of how genes are switched on and off during the development and lifetime of an organism is central to developing the ability to fight many diseases in a rational way. This project will advance our knowledge in this area at a fundamental molecular level by examining the mechanisms through which a specific set of proteins controls gene expression.
