Rhombomeric Topography of Structures in the Adult Mouse: Evidence from Avian Homologies and Transgenic Mice. The brainstem of birds has been shown to be formed by a line of segments, like carriages of a train. The same arrangement exists in the embryos of mammals, but is hidden in the adult mammalian brain. We will transfer our detailed knowledge of bird brains to make a maps of the brainstem segments in adult mice.

We will transfer our detailed knowledge of bird brains to make a maps of the brainstem segments in adult mice. We will then test this map with special gene markers which will reveal the occult segmental pattern in adult mice. This work will give us a new way of understanding the organisation of brainstem centres that control breathing, cardiovascular functions and emotional states.Read moreRead less

The high-speed confocal microscope live cell recording system we are establishing represents new generation equipment. It allows quality imaging of selected subcellular regions of live cells combined with simultaneous electrophysiological recording at rates and sensitivity hitherto not possible. This equipment provides a window of opportunity for major research advances in that it allows real-time two and three-dimensional imaging of fundamental cellular activities that previously could not be viewed. It will allow major advances in priority health-related research and will provide an ideal research tool to introduce young scientists and students to cutting edge research.Read moreRead less
Central command neurons integrating cardiorespiratory drive in exercise. The ability to perform exercise is fundamental to human health and welfare. This ability depends upon the co-ordination by the brain of respiratory and cardiovascular function, such that the delivery of oxygen to exercising muscles is maximised. This project will test the idea that there is a specific group of neurons in the brain that drive both the respiratory and cardiovascular changes that occur during exercise, and w ....Central command neurons integrating cardiorespiratory drive in exercise. The ability to perform exercise is fundamental to human health and welfare. This ability depends upon the co-ordination by the brain of respiratory and cardiovascular function, such that the delivery of oxygen to exercising muscles is maximised. This project will test the idea that there is a specific group of neurons in the brain that drive both the respiratory and cardiovascular changes that occur during exercise, and will determine the location and functions of such neurons. Such new knowledge will help us understand how the brain optimises the ability of the body to perform exercise. This is of fundamental importance in sports science, a field in which Australia excels.Read moreRead less
Improved identification of patients 'at risk' of depression, and optimal targeting of rehabilitation post-stroke through novel brain imaging and biomarkers. Use of novel brain imaging and biomarkers for identification of stroke survivors at risk of depression and recurrent stroke will permit early access to preventative and effective treatments for depression and improve capacity to benefit from rehabilitation. Development of predictive models to guide selection of most optimal rehabilitation st ....Improved identification of patients 'at risk' of depression, and optimal targeting of rehabilitation post-stroke through novel brain imaging and biomarkers. Use of novel brain imaging and biomarkers for identification of stroke survivors at risk of depression and recurrent stroke will permit early access to preventative and effective treatments for depression and improve capacity to benefit from rehabilitation. Development of predictive models to guide selection of most optimal rehabilitation strategies based on viable brain will maximise the capacity for persons with stroke to reach their full potential for recovery and ensure rehabilitation is more targeted and cost efficient. Improved capacity to benefit from treatment will have ongoing benefits for activity participation and productive living in Australians who experience stroke.Read moreRead less
Unravelling the sub-nuclear complexity of the brain. Understanding the function of the brain is a major frontier of scientific research. The ability to increase knowledge of brain function is reliant upon the development of novel methods.

The ability to increase knowledge of brain function is reliant upon the development of novel methods. This application will develop a novel approach for understanding the function of particular nerve cells. One outcome will be demonstration of the applicability of a novel method of benefit to all brain researchers. Another outcome will be increased understanding of one brain region that is known to contribute to the development of cardiovascular disease. It is expected that increased knowledge of brain function will lead to novel theories of brain disease and therapeutic strategies.Read moreRead less

A redox sensor and triple receptor function for guanylyl cyclase. Nitric oxide (NO) protects from blood vessel spasms and clot formation. Conversely, insufficient NO occurs in cardiovascular disease. Life-saving drugs like glycerol trinitrate supply more NO to blood vessels, however these drugs are limited in their action when their target protein (NOGC) is decreased or defective, eg. in hypertension or arteriosclerosis. We have elucidated the reason for this defect and simultaneously discovered ....A redox sensor and triple receptor function for guanylyl cyclase. Nitric oxide (NO) protects from blood vessel spasms and clot formation. Conversely, insufficient NO occurs in cardiovascular disease. Life-saving drugs like glycerol trinitrate supply more NO to blood vessels, however these drugs are limited in their action when their target protein (NOGC) is decreased or defective, eg. in hypertension or arteriosclerosis. We have elucidated the reason for this defect and simultaneously discovered an entirely novel group of drugs which activate NOGC without NO. Impressively, these drugs are most effective in diseased blood vessels. The aim is the development of novel blood pressure lowering/anti-anginal drugs with higher effectiveness and less side-effects because they work in an entirely new way.Read moreRead less

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

This project will benefit our community by providing the basic cell biology knowledge required to understand disease mechanisms and ultimately provide avenues for better treatments. Aspects of the project will focus on the modification of apoE by carbohydrates and the interaction of apoE with cellular carbohydrate-containing structures. The importance of carbohydrates in the regulation of cellular and protein function is increasingly recognised and forms a foundation for the rapidly expanding discipline of glycobiology. This project will strengthen Australia's glycobiology research capacity.Read moreRead less
Molecular control of apoptosis and protein homeostasis. A million cells are produced every second by cell division. At the same time a million cells commit suicide by a process called apoptosis. When cells fail to die when they should they can develop into cancers.

A million cells are produced every second by cell division. At the same time a million cells commit suicide by a process called apoptosis. When cells fail to die when they should they can develop into cancers. In heart attacks, stroke and neurodegenerative diseases, many cells appear to activate their self destruct mechanism to die unnecessarily. Drugs that can cause cancer cells to kill themselves, or drugs that prevent cells dying when they shouldn't, would make a major impact on many important diseases. Understanding the molecular mechanisms of cell death is the first step towards developing these drugs.Read moreRead less
