Summary
Alzheimer’s disease is characterised by the deposition of amyloid plaques in the brain. We don’t fully understand how amyloid deposition occurs and what contribution is made by genetic and environmental factors. Amyloid deposition in the brain can now be quantified during life using positron emission tomography. In this study, we will examine brain amyloid in twins, which will determine what proportion of the pathology is attributable to environmental factors that may be modifiable.
Therapeutic Targeting Of Neuroinflammation To Slow The Progression Of Neurodegenerative Disease

Funding Amount
$463,652.00
Summary
My research has identified key components of our immune system, that can worsen disease in conditions such as Parkinson’s disease and motor neuron disease. I hope that exploring these components in animal models, and patients suffering from these diseases, my group can identify new therapeutic drug candidates that can be progressed in clinical trials. Ultimately, this may lead to new treatments to reduce disease burden in patients suffering from these neurodegenerative conditions.
Radiological Features Correlating With Seizures In Patients With Supratentorial Gliomas

Funding Amount
$47,877.00
Summary
Gliomas are the most common brain tumours, with more than 1,500 new cases diagnosed in Australia each year. Around 50% of all glioma patients suffer from seizures, which are difficult to control with current anti-epileptic drugs. The epilepsy and the side-effects of the drug therapies are a major cause of morbidity and impaired quality of life. It is also a significant burden on the economy, leading to more and longer hospital admissions, and loss of productivity for both patients and carers.
The Role Of Innate Immune Memory In The Transition From Acute To Chronic Pain

Funding Amount
$331,440.00
Summary
Chronic pain costs Australians more than $34 billion annually and is the 3rd highest Australian disease burden. It has long been thought to be a disease of the wiring of the brain. This project aims to challenge this long held belief by examining the impact of the immune system in creating chronic pain. Such work promises to provide new and better ways to prevent chronic pain, which will improve & maintain good health for all Australians.
Transcriptional control of neural stem cell differentiation during development and disease. Understanding the molecular mechanisms that control how neural stem cells differentiate is critical to provide potential therapeutic treatment for neurodegenerative diseases and for brain cancer. This project will aim to discover, using an animal model system, the genes and molecules regulating these key biological processes.

The equipment requested will facilitate the work of the Australian Mouse Brain Mapping Consortium, a consortium of Australian research groups collaborating to provide the only mouse model brain mapping capability in the country. The consortium brings together laboratory, neuroimaging and computational expertise in a comprehensive framework for imaging the mouse brain. This will help researchers to study mouse models of genetic and acquired disorders across the life-span. Remote viewing and analysis capabilities will help overcome the 'tyranny of distance', increasing national access to the facility. Repositories of digitised images will increase the availability of valuable research material to other Australian and international researchers.Read moreRead less
Old brain cells perform new tricks to allow life-long learning. In the brain, nerve cells transmit electrical signals more quickly and reliably when they are insulated. The insulating cells undergo small adaptive changes that speed up information transfer during learning, and the faster the electrical signal, the better the learning outcomes. This project aims to understand the signals that direct insulating cells to adapt and support life-long learning. In the longer term, this knowledge may be ....Old brain cells perform new tricks to allow life-long learning. In the brain, nerve cells transmit electrical signals more quickly and reliably when they are insulated. The insulating cells undergo small adaptive changes that speed up information transfer during learning, and the faster the electrical signal, the better the learning outcomes. This project aims to understand the signals that direct insulating cells to adapt and support life-long learning. In the longer term, this knowledge may be used to: develop interventions that improve learning and educational outcomes; counteract age-related memory decline and enable longer work force participation; develop strategies to circumvent the memory loss caused by brain diseases, or improve the design of computer hardware.Read moreRead less
Cellular and Neurochemical Basis of Drug Addiction. Addiction to the major drugs of abuse, including heroin, amphetamines, cocaine, nicotine and alcohol damage the lives and cause premature death of more than 20% of Australians. Addiction produces long-term disruption of brain processes that lead to loss of control over urges to consume drugs and persistent cycles of relapse to drug taking. This research will apply new neurochemical approaches to discover mechanisms of disrupted brain function t ....Cellular and Neurochemical Basis of Drug Addiction. Addiction to the major drugs of abuse, including heroin, amphetamines, cocaine, nicotine and alcohol damage the lives and cause premature death of more than 20% of Australians. Addiction produces long-term disruption of brain processes that lead to loss of control over urges to consume drugs and persistent cycles of relapse to drug taking. This research will apply new neurochemical approaches to discover mechanisms of disrupted brain function that occur during development of addiction and relapse that are critical for development of better strategies to treat the disorder.

Molecular control of adult neural stem cell quiescence. The objective of this project is to improve our understanding of adult neural stem cell biology and function. Within the central nervous system of the brain, neural stem cells persist throughout adult life. These cells continually produce new neurons that are pivotal for processes including learning and memory, and deficits in adult neurogenesis have been linked to age-related cognitive decline. Adult neural stem cells are predominantly qui ....Molecular control of adult neural stem cell quiescence. The objective of this project is to improve our understanding of adult neural stem cell biology and function. Within the central nervous system of the brain, neural stem cells persist throughout adult life. These cells continually produce new neurons that are pivotal for processes including learning and memory, and deficits in adult neurogenesis have been linked to age-related cognitive decline. Adult neural stem cells are predominantly quiescent, dividing rarely to ensure that they are not prematurely exhausted. However, the factors that maintain this quiescence are very poorly defined. The project aims to understand how stem cell quiescence is controlled at both a molecular and cellular level in vivo within the adult mouse brain.Read moreRead less
