Summary
When adverse events occur, the lateral habenula, an old brain nucleus, helps calculate the wisest corrective action by contributing to the “brake” that controls the brain’s dopamine reward system. Our research will show how the lateral habenula links corrective changes in behavior with coordinated changes in temperature. Understanding this link will greatly contribute to understanding the brain mechanisms that regulate our physiology during stressful situations and as part of mental illness.
Mapping sites of visceral convergence connecting the colon and bladder. This project aims to develop multiple neuroanatomical approaches to identify where in the central nervous system the sensory signalling from the colon and bladder merge. The combination of such technologies is novel to the study of the central circuits relaying colon/bladder convergence into the brain and will generate new and detailed knowledge of the central pathways in which pelvic organ sensory (discomfort) and motor (de ....Mapping sites of visceral convergence connecting the colon and bladder. This project aims to develop multiple neuroanatomical approaches to identify where in the central nervous system the sensory signalling from the colon and bladder merge. The combination of such technologies is novel to the study of the central circuits relaying colon/bladder convergence into the brain and will generate new and detailed knowledge of the central pathways in which pelvic organ sensory (discomfort) and motor (defecation/urination) functions are coordinated. The expected outcomes are predicted to aid future discovery of mechanisms of cross-organ sensitisation and are anticipated to provide significant benefit to therapy development for chronic visceral pain syndromes associated with bowel and bladder dysfunction.Read moreRead less
Ultradian rhythms in basal metabolism; relationship to thermoregulation, cardiovascular function and behavioural arousal. Results from this project will be of basic theoretical biological importance, and may well provide a foundation for understanding basal metabolic regulation and its link with cardiovascular function. Our findings may provide a new foundation for discovering strategies that alter basal metabolic rate in a manner that improves health and reduces the incidence of obesity related ....Ultradian rhythms in basal metabolism; relationship to thermoregulation, cardiovascular function and behavioural arousal. Results from this project will be of basic theoretical biological importance, and may well provide a foundation for understanding basal metabolic regulation and its link with cardiovascular function. Our findings may provide a new foundation for discovering strategies that alter basal metabolic rate in a manner that improves health and reduces the incidence of obesity related disease such as heart attack and stroke. Thus this research proposal is of special relevance to National Research Priority 2: Promoting and Maintaining Good Health. Obesity and obesity-related medical conditions particularly affect older people, so that our research is also highly relevant to National Research Priority 2 sub-areas: Ageing well, Ageing productively.Read moreRead less

Summary
Pain and discomfort from the gut are common and unpleasant. We understand how gut sensory nerve cells work, at the cellular, molecular and genetic level. However, movement of the gut wall and contents are the major cause of activation of sensory neurons. We know little about which particular patterns of movement cause pain. This is crucial information for accurately diagnosing human gut disorders, for monitoring effectiveness of treatments and for identifying potential new drug targets.

Establishment of a South Australian rTMS Facility. It is proposed to establish a South Australian Facility for rapid rate transcranial magnetic stimulation (TMS) which will be the only one in Australia.

It is proposed to establish a South Australian Facility for rapid rate transcranial magnetic stimulation (TMS) which will be the only one in Australia. This Facility will provide enormous opportunities for collaborative cutting edge investigations into the role of the human cortical areas in a diverse range of tasks. For example, projects have been identified projects employing rTMS to study sensorimotor cortical plasticity, facilitate functional recovery following stroke and investigate the mechanisms of savant behaviour. Provision of this Facility will provide further support for this productive and internationally renowned group of scientists to develop their research programs.Read moreRead less
Afferent stimulation-induced plasticity and its functional significance. Certain regions of the brain can reorganise (plasticity) during motor learning or when there is damage to peripheral nerves or muscles. There is a large body of evidence for these plastic changes in animals. Until recently data showing that similar changes occurred in humans was limited. However, we have recently demonstrated that certain patterns of peripheral stimulation can indeed induce similar changes in human subjects ....Afferent stimulation-induced plasticity and its functional significance.

There is a large body of evidence for these plastic changes in animals. Until recently data showing that similar changes occurred in humans was limited. However, we have recently demonstrated that certain patterns of peripheral stimulation can indeed induce similar changes in human subjects. These findings are important for our understanding of the mechanisms of motor control and learning.Read moreRead less
Insect-inspired flapping wing robots: autonomous flight control systems. This project aims to design a novel control scheme for insect-inspired, flapping-wing, micro aerial vehicles. This type of micro aerial vehicle has complex, periodic, time-varying and inherently unstable dynamics, which are practically challenging to model and implement in hardware. This project will design energy-based automatic stabilization and task-dependent control, and develop the insect-inspired platform for testing ....Insect-inspired flapping wing robots: autonomous flight control systems.

This type of micro aerial vehicle has complex, periodic, time-varying and inherently unstable dynamics, which are practically challenging to model and implement in hardware. This project will design energy-based automatic stabilization and task-dependent control, and develop the insect-inspired platform for testing nonlinear control strategies. The expected outcomes will include new system and control theories, concepts, principles and technologies in controller design that can provide reliable flight control for bio-inspired, flapping-wing systems.Read moreRead less
"Evidence based" evaluation of treatment in ADHD.

Attention deficit hyperactivity disorder (ADHD) is marked by limitations in diagnostic accuracy, psychobiological characterisation and assessment of treatment efficacy. A national consortium of scientists and clinicians is planning to address these issues using an assessment protocol recently developed by the Brain Resource Company Ltd, which involves integrated neuroscientific and psychometric measurement that taps many of the brain's information processing networks. Specifically, the aims of the project are to identify biological and cognitive markers that reflect ADHD in its untreated form, and markers that discriminate treatment effects relative to the pre treatment profile. The results from this study will be translated into a product that uses the protocol to provide a service able to profile ADHD more accurately and evaluate the effects of treatment.Read moreRead less

Summary
Characterisation of visceral afferent spinal cord pathways. Sensory nerves in the gut wall are key mediators of chronic visceral pain. This project will characterise how sensory nerves supplying the bowel connect to the spinal cord and the spinal circuits mediating pain perception, providing information to identify sensory pathways underlying visceral pain.
