How The Lateral Habenula Integrates Behavioral And Autonomic Functions: The VTA Dopamine Connection

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.
Mechanical Factors In Normal Human Colonic Motility

Summary
Abnormal human colonic contractions cause significant medical, societal and financial burdens. Diagnosis and treatment of motility disorders requires an understanding of normal colonic contractility against which to measure dysfunction. Through state-of-the-art recording and analytical techniques, developed by the applicants, this project will provide the first clear description of normal human colonic motor patterns and how they are generated.

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. 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 functiona ....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. 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. 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. These findings are important for our understanding of the mechanisms of motor control and learning.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 informati ...."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
Central pathways regulating visceral pain. This project aims to investigate the neural pathways within the spinal cord and brain processing colorectal pain perception. The project aims to identify the spinal cord neurons relaying colorectal signalling into the brain and the influence of descending modulation from the brainstem upon these pathways. The outcomes will greatly benefit fundamental understanding of the central pathways processing visceral pain.
Toll Like Receptor signalling as a mediator of sex differences in pain, opioid and alcohol action. Brain immunology will be examined in this project to see if the signalling of a receptor called Toll Like Receptor 4 can explain sex differences in pain, and the action of pain killers and alcohol. These findings will have significant implications on the understanding of male and female brains, and will assist in the design of new drugs to treat brain and spinal cord diseases.
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
Proteomic analysis of central nervous system inflammation in multiple sclerosis. This project aims to identify new therapeutic targets and diagnostics for Multiple Sclerosis (MS) the most common neurological disease in young adults. The estimated economic burden of this disease in Australia is around $2 billion per annum. There is also a large social cost to take into account. In spite of a great deal of research, current therapies are limited.

The estimated economic burden of this disease in Australia is around $2 billion per annum. There is also a large social cost to take into account. In spite of a great deal of research, current therapies are limited. We expect that this this research will: lead to new therapies and better diagnostics, which will reduce the financial and human cost of this disease; generate IP with subsequent economic benefits and; expand proteomics technologies which will have flow on effects including economic benefits and benefits to a wide range of basic research.

Summary
The Science of Learning Research Centre. In this innovative new Centre, researchers in education, neuroscience and cognitive psychology will work together with teachers to understand the learning process. This collaboration will establish new criteria to assess the impact of different types of learning and strategies to inform teaching practices of benefit to all Australians.
