Identifying genes that influence clinical course and susceptibility in multiple sclerosis. This project aims to identify the genetic basis of multiple sclerosis (MS), the most common neurologic disease in young Australian adults. MS urgently needs research to identify predisposition, aid early diagnosis and provide bona fide molecular targets for new therapies. This will benefit people with MS and those susceptible to it. Crucial new knowledge identified will benefit other major areas of MS rese ....Identifying genes that influence clinical course and susceptibility in multiple sclerosis. This project aims to identify the genetic basis of multiple sclerosis (MS), the most common neurologic disease in young Australian adults. MS urgently needs research to identify predisposition, aid early diagnosis and provide bona fide molecular targets for new therapies. This will benefit people with MS and those susceptible to it. Crucial new knowledge identified will benefit other major areas of MS research including epidemiology, immunology and neurobiology. Collaboration of 8 major Australian institutions is also important for this project and future studies. The team will have access to a new national MS GeneBank (platform) with samples from 2240 patients that should generate findings important to world-wide MS genetic knowledge.Read moreRead less
Psychiatric disorders in epilepsy. Psychiatric disorders, such as depression, anxiety and cognitive disorders, are frequently observed in patients with epilepsy. Although standard dogma suggests that psychiatric disorders are a consequence of living with epilepsy, recent evidence suggests a bidirectional relationship between these disorders, such that depression and other psychiatric illnesses act as risk factors for epilepsy development. This project will utilise basic science approaches to und ....Psychiatric disorders in epilepsy. Psychiatric disorders, such as depression, anxiety and cognitive disorders, are frequently observed in patients with epilepsy. Although standard dogma suggests that psychiatric disorders are a consequence of living with epilepsy, recent evidence suggests a bidirectional relationship between these disorders, such that depression and other psychiatric illnesses act as risk factors for epilepsy development. This project will utilise basic science approaches to understand the causal relationships between epilepsy and psychiatric disorders, and determine how and why psychiatric disorders and epilepsy co-exist. It is hoped that research conducted in this project will develop novel avenues to treatment of both epilepsy and psychiatric disorders.Read moreRead less

This project is anchored in the fundamental understanding of complex vertebrate behaviours, namely cognition. Little is known about the molecular and neural substrates underpinning complex higher order information processing. This project aims to dissect the functional role of synaptic genes that are essential for organising neuronal connections, in distinct cognitive processes and how these functions may be regulated by other genes, drugs or environmental factors. This project aims to employ state-of-the-art technologies to address the evolutionary biology of complex cognitive behaviours, towards further understandings how brain function evolved and the mechanisms that have enabled humans to perform highly complex and intricate tasks.Read moreRead less
The role of synapse development in cognitive disorder. In humans, intellectual disability occurs when nerve cells in the brain fail to connect. The project examines fundamental molecular processes involved in synapse development of neurons. The use of insect models provides a generalised biological template to understand how synaptic molecules contribute to behaviours that underlie cognitive disorder.

Glial Plasticity: How experience and aging change brain structure. 50 % of the cells in the brain are called glia. These cells work with neurons to regulate how we think, feel and behave. Most glial cells are added to the brain after birth, however we know very little about how this process works, or how it may be changed by lived-experience. The overarching aim of this study is to better understand how lived-experience impacts the growth of the major types of glial cells in the brain.

These cells work with neurons to regulate how we think, feel and behave. Most glial cells are added to the brain after birth, however we know very little about how this process works, or how it may be changed by lived-experience. The overarching aim of this study is to better understand how lived-experience impacts the growth of the major types of glial cells in the brain. To do this, I will use cutting-edge technologies and identify; 1) the rates of cell growth for the major types of glia, and 2) map how they are integrated into the brain. This will lead to important new information on how lived-experience can shape the growth and structure of the brain.Read moreRead less

This project aims to map the brain circuits controlling fluid and salt intake using innovative genetically encoded techniques, which enable precise targeting and manipulation of select neuronal populations. Expected outcomes of this project include constructing detailed maps of the brain circuits for fluid and salt intake by tracing multiple nodes in the network, characterising neuronal populations, and precisely defining their functions. This should provide significant benefits including understanding the brain regions controlling fluid and salt intake which are essential for maintaining fluid homeostasis, and providing a framework for investigating the neural circuits underlying other complex behaviours.Read moreRead less

Summary
Our research aims to identify how specific brain cells detect changes in glucose levels and how ageing and diet affect their function. We identified a subset of nerve cells that detect changes in glucose and the “hunger” hormone ghrelin, their ability to do so adapting with age and nutritional status. This project will investigate the potential of these nerve cells as targets for therapeutic and diet- intervention strategies to target obesity, diabetes and promote healthy ageing.
The development and testing of a device to enhance the application of repetitive transcranial magnetic stimulation. This project aims to develop and evaluate a new device designed to substantially enhance the use of transcranial magnetic stimulation, a technology, which is increasingly being applied in the treatment of disorders such as depression, as well as in the study of normal and abnormal brain function.
Early life overfeeding - mechanisms for programming obesity and long-term immune dysfunction. Early life overfeeding can lead to obesity and related changes in adulthood. With this study we will discover how overfeeding can permanently alter an animal's development so that its body weight and immune functions are dysregulated. The outcomes will facilitate appropriate design of animal experiments considering the impact of neonatal programming.

Early life overfeeding can lead to obesity and related changes in adulthood. With this study we will discover how overfeeding can permanently alter an animal's development so that its body weight and immune functions are dysregulated. The outcomes will facilitate appropriate design of animal experiments considering the impact of neonatal programming. They will also contribute to more efficient feeding protocols for meat production in agriculture and identify targets for risk management and for preventing and ameliorating early life overfeeding effects in humans. This investigation therefore has clear benefits to the social, economic, and health aspects of obesity and to basic science and agriculture.Read moreRead less
The impact of female sex hormones on neurodevelopment. This project aims to characterise the contribution of sex hormones to the development of emotional brain circuits in female adolescents. Puberty is associated with profound changes in emotional behaviours in females, but we know little about the underlying brain mechanisms. In particular, research has neglected to consider the role of the sex hormones for which changes are a defining feature of female puberty (eg, oestradiol).

This project aims to characterise the contribution of sex hormones to the development of emotional brain circuits in female adolescents. Puberty is associated with profound changes in emotional behaviours in females, but we know little about the underlying brain mechanisms. In particular, research has neglected to consider the role of the sex hormones for which changes are a defining feature of female puberty (eg, oestradiol). This work will be the first to comprehensively advance our understanding of the unique role of sex hormones in shaping the adolescent female brain. It will provide critical understanding of how individual differences in hormonal factors increase risk for emotional problems in females, and inform treatment strategies.Read moreRead less
