Development of integrated biological markers of brain function. With the rapid growth of both brain imaging and genetics, we can now examine the biological basis of complex brain functions, such as memory. Our goal is to combine these techniques to develop evidence-based biological markers of normal function. These markers can then be used to screen for early signs of abnormal function (eg. in Alzheimer's disease) and to assess treatment effects. Two unique features ensure the project's feasibil ....Development of integrated biological markers of brain function. With the rapid growth of both brain imaging and genetics, we can now examine the biological basis of complex brain functions, such as memory. Our goal is to combine these techniques to develop evidence-based biological markers of normal function. These markers can then be used to screen for early signs of abnormal function (eg. in Alzheimer's disease) and to assess treatment effects. Two unique features ensure the project's feasibility: a) access to the first standardized, normative brain database (from the Brain Resource Company Ltd) and b) a scientific collaboration supporting the integration of brain imaging and genetics.Read moreRead less
The effect of cochlear implants on cognitive decline in ageing Australians. This project aims to investigate the impact of cochlear implants on cognitive function in elderly people with deafness. Deafness has been found to be independently associated with a 30–40 per cent accelerated rate of cognitive decline in elderly adults. There is currently no effective treatment for cognitive decline. The intended outcomes of this observational study will help us to understand the biological process of co ....The effect of cochlear implants on cognitive decline in ageing Australians. This project aims to investigate the impact of cochlear implants on cognitive function in elderly people with deafness. Deafness has been found to be independently associated with a 30–40 per cent accelerated rate of cognitive decline in elderly adults. There is currently no effective treatment for cognitive decline. The intended outcomes of this observational study will help us to understand the biological process of cognitive decline, whether hearing loss is causal, and whether the process can be altered. These findings should be applicable to all individuals with hearing loss. If cochlear implants delay cognitive decline, this would significantly affect policy, quality of life for the elderly, and the cost to society.Read moreRead less
The role of attention re-training in pain tolerance. Chronic pain is one of the most debilitating and expensive chronic health problems in westernized countries. Chronic pain develops when an individual is injured and is fearful of the pain that they experience. This causes them to become hypervigilant to pain, avoid activity and results in a vicious cycle of increasing disability. This research has two, related aims. First, we aim to test this model to see whether hypervigilance influences resp ....The role of attention re-training in pain tolerance. Chronic pain is one of the most debilitating and expensive chronic health problems in westernized countries. Chronic pain develops when an individual is injured and is fearful of the pain that they experience. This causes them to become hypervigilant to pain, avoid activity and results in a vicious cycle of increasing disability. This research has two, related aims. First, we aim to test this model to see whether hypervigilance influences response to pain, as predicted. Second, we will develop and test an intervention to reduce hypervigilance to pain in healthy people and those with acute injuries. If the intervention is successful, it will have the potential to prevent the development of chronic pain or reduce its severity.Read moreRead less
Motherhood choices: a decision aid for women with rheumatoid arthritis. Decisions about pregnancy in the context of debilitating rheumatoid arthritis impact directly on both the mother and the child as well as their family and wider social unit. Providing evidence-based information to support women in making informed decisions about motherhood is critical in maximizing the well-being of the mother and ensuring a healthy start to life for a baby. The project will contribute to the national resear ....Motherhood choices: a decision aid for women with rheumatoid arthritis.

Providing evidence-based information to support women in making informed decisions about motherhood is critical in maximizing the well-being of the mother and ensuring a healthy start to life for a baby. The project will contribute to the national research priority area of promoting and maintaining good health, addressing the goal of supporting a healthy start to life.Read moreRead less
Validation of a New Conceptual Model of ADHD based on Underlying Central Nervous System Dysfunction. ADHD is a debilitating problem that affects 5% of children and approximately half as many adults. ADHD causes substantial problems at school and if untreated, predisposes the individual to increased drug and alcohol use, marital breakdown, criminal prosecution and psychiatric problems in later life. One problem is that we do not fully understand what are the causes of the disorder. This project w ....Validation of a New Conceptual Model of ADHD based on Underlying Central Nervous System Dysfunction. ADHD is a debilitating problem that affects 5% of children and approximately half as many adults. ADHD causes substantial problems at school and if untreated, predisposes the individual to increased drug and alcohol use, marital breakdown, criminal prosecution and psychiatric problems in later life. One problem is that we do not fully understand what are the causes of the disorder. This project will test the validity of several models of brain dysfunction in ADHD which have been influential in the literature, but poorly tested. Through better understanding of the basic underlying problems, more effective intervention can be developed.Read moreRead less
The efficacy of a physical activity intervention in the management of psychological and physical symptoms among breast and prostate cancer patients. The vastly improved survival rates for breast and prostate cancer in recent years has resulted in an ever-increasing number of people living with a history of cancer. Treatment for cancer is often associated with negative side effects like fatigue, depression and sleep disturbance, and an overall impaired quality of life.

The vastly improved survival rates for breast and prostate cancer in recent years has resulted in an ever-increasing number of people living with a history of cancer. Treatment for cancer is often associated with negative side effects like fatigue, depression and sleep disturbance, and an overall impaired quality of life.
This project will assess the effectiveness of a physical activity program in alleviating these symptoms of treatment. The program will include regular walking and gentle resistance strength training.
The outcomes from the project will advance research by shedding light on which symptoms are most helped by physical activity, and how much activity is needed to gain these benefits.

The role of context in the acquisition, extinction and reinstatement of fear. Behavioural studies have identified a role for context in the development, extinction and reactivation of fear memories. Although there has been significant progress in delineating the neural pathways for fear conditioning, less is known about the substrates that represent the context of conditioning. This project studies the neural substrates of the processes by which context controls the acquisition, extinction and r ....The role of context in the acquisition, extinction and reinstatement of fear. Behavioural studies have identified a role for context in the development, extinction and reactivation of fear memories. Although there has been significant progress in delineating the neural pathways for fear conditioning, less is known about the substrates that represent the context of conditioning. This project studies the neural substrates of the processes by which context controls the acquisition, extinction and reactivation of fear memories. Specifically, it examines the role of information flow between the dorsal subiculum and the accumbens nucleus in the processes by which rats learn about environmental context and the control exerted by such contexts on fear memories.Read moreRead less

Attention-Deficit/Hyperactivity Disorder (AD/HD) is a debilitating problem affecting 5% of children. AD/HD causes substantial school problems and predisposes the child to drug and alcohol abuse, marital breakdown, criminal prosecution and psychiatric problems in later life. At present we know very little about the underlying causes of the behavioural changes seen in this disorder. This project will clarify the maturational abnormalities in brain function that occur from childhood through to adulthood in this disorder. Better understanding of the normal developmental paths of this disorder will have major clinical benefits as it will allow the development of more optimal treatment plans for these children.Read moreRead less
The sociopath amongst us: the neural basis of empathy disorders. Empathy is fundamental to human relations. Despite this, little is known about its underlying mechanisms. This project tests whether empathy relies upon us simulating the emotion of others in ourselves, and if so, at which stage this occurs.

Despite this, little is known about its underlying mechanisms. This project tests whether empathy relies upon us simulating the emotion of others in ourselves, and if so, at which stage this occurs. It is significant because it tests several competing theories to advance a coherent model of empathy that can be used to understand human social behaviour. It is innovative because it focuses on adults with brain lesions. This is a powerful means to examine brain mechanisms underpinning empathy, yielding insights not available from observation of healthy adults. It is expected to provide a leap forward in understanding the neuroscience of social behaviour.Read moreRead less
Noradrenaline in learning produced by negative prediction error. This project aims to examine the role of the neurotransmitter noradrenaline in error-driven learning. While dopamine may be involved in initial learning about events, updating this learning, notably when reward is omitted, involves noradrenaline.

This project aims to examine the role of the neurotransmitter noradrenaline in error-driven learning. While dopamine may be involved in initial learning about events, updating this learning, notably when reward is omitted, involves noradrenaline. Predictive learning is adaptive; it allows animals to use information in the environment to anticipate and prepare for events. Animals can also update learned associations when confronted with new information and environmental contingencies. This project expects to provide information about how noradrenaline signals reward prediction errors and how predictive information is detected, encoded and modified using cutting edge behavioural and neuroscience tools.Read moreRead less
