Perceiving Is Believing: Perceptual Inference Anomalies In Schizophrenia.
Funder
National Health and Medical Research Council
Funding Amount
$344,824.00
Summary
In this study we explore the brain-ability-behaviour relationships that can explain causes of the severe mental illness, schizophrenia. Changes in the brain in schizophrenia affect how people perceive the world around them. Perception relies on our ability to use information in memory to shape what we perceive. We will study brain activity and task abilities that help us to understand where why and how this process becomes disrupted in the brain in persons with schizophrenia.
Elucidating The Role Of Transthalamic Pathways In Cortical Processing
Funder
National Health and Medical Research Council
Funding Amount
$792,688.00
Summary
Your brain senses the world and produces a suitable motor response by processing information between brain regions, such as primary sensory cortex to secondary cortex. Surprisingly, cortical pathways have a parallel route through the thalamus (transthalamic pathways) but their function is entirely unknown. We will use novel genetic and viral tools to shut down neural pathways while mice make decisions, thus identifying new circuits in our understanding of disorders with cognitive deficits.
Harnessing Neural Plasticity To Improve Functional Outcomes Following Burn Injury.
Funder
National Health and Medical Research Council
Funding Amount
$667,984.00
Summary
Burn is painful and leads to long-term functional impairment and increased chronic disease. Pain and peripheral injury induce changes in the brain that can be functionally beneficial or maladaptive, yet we know little about brain changes following burn injury. This project will identify the mechanisms and functional impact of neural plasticity after burn injury, and test the efficacy of a neural intervention to reduce pain and improve functional recovery following burn injury.
Unravelling The Behavioural And Brain Mechanisms Of Compulsive Disorders, And New Ways To Treat Them
Funder
National Health and Medical Research Council
Funding Amount
$635,076.00
Summary
Disorders of compulsion, such as obsessive-compulsive disorder and substance use disorder, are chronic, debilitating, and present a significant cost to the individual and to society. Together, these disorders affect more than 10% of the population. Moreover, 40-60% of these individuals are resistant to current treatment. The current project is aimed at improving the preclinical research underlying our understanding the behavioural and brain mechanisms of such disorders and how to treat them.
Advancing The Spatial Analysis Of Cells In Tissues To Profile The Tumour Microenvironment
Funder
National Health and Medical Research Council
Funding Amount
$187,918.00
Summary
Tumours are composed of a mix of different cells, including cancer cells, immune cells and other cells supporting tumour growth. These cells are not organised randomly, but rather are distributed in specific patterns. Here we will develop computational methods to detect these patterns and determine what statistical tests should be used to compare samples. This project will give us the tools to investigate how the location of cells in tissues relates to treatment response and survival.
Identifying Unintentional Effects Of Medication Using Statistical Genetics Analyses Of Large-scale Genetic And Genomic Data
Funder
National Health and Medical Research Council
Funding Amount
$251,441.00
Summary
An increasing number of studies have highlighted unknown adverse effects of medication, for example, use of statins to lower cholesterol with increased risk of type 2 diabetes. The gold standard approach to confirm these effects is randomised control trials, which may not always be feasible or ethical, and are very expensive. This project aims to apply innovative statistical genetics approaches to (genetic and genomic) 'big-data' to predict unknown effects of commonly prescribed medications.
Sudden cardiac death (SCD) is a devastating consequence of a number of heart diseases. Underlying causes include inherited heart muscle problems (cardiomyopathies), with no cause found in 40%. Our study will investigate the role of 'concealed cardiomyopathy' cases, i.e. those with a SCD event with no evidence of heart disease, but carry errors in heart genes. Our findings will translate rapidly into more targeted clinical and genetic evaluation of families with the ultimate goal to prevent SCD.
Biomechanics Meets Phenomics: Towards Understanding And Predicting Abdominal Aortic Aneurysm (AAA) Disease Progression
Funder
National Health and Medical Research Council
Funding Amount
$1,324,897.00
Summary
The criterion used to decide whether to operate on an abdominal aortic aneurysm (AAA), based on the maximum diameter, does not take into consideration the rupture risk for a given patient. By combining imaging, computational biomechanics and metabolic phenotyping, we will assess the structural integrity of an AAA and local structural changes of systemic response. These will allow improved differentiation of rupture risk, leading to better outcomes for patients and savings for the health system.
ARX- A Hub Gene For A Common Biological Pathway In Schizophrenia
Funder
National Health and Medical Research Council
Funding Amount
$707,974.00
Summary
Schizophrenia is a severe psychiatric disorder with no cure. I have identified that some people with schizophrenia show variations to a gene called ARX. This project will use preclinical mouse models to explore how variations to the Arx gene affect brain molecules, networks of cells and behavioural outcomes. This biological pathway will provide the framework for the identification of new molecules to target therapeutically to modify the biological course of schizophrenia and improve outcomes.
Discovering How A Novel Anti-malarial Drug Series Rapidly Kills Parasites
Funder
National Health and Medical Research Council
Funding Amount
$672,971.00
Summary
We have developed a new set of highly potent anti-malarial drugs but we do not know how they work. Identifying how these compounds work is important for improving their effectiveness and safety. We will discover how these drugs kill parasites by using a number of cutting edge methods that could also be useful for discovering how other drugs work. Data generated will progress these compounds along the drug development pipeline which urgently needs a constant supply of new antimalarials.
