Summary
Humans and other animals can optimise their goal-directed behaviour by linking stimuli or actions to consequent positive and negative rewards. How does an animal generate such associations, and make decisions in the natural environment where the associations are often uncertain, at times contradictory, and continuously changing? This project uses rat whisker system as an animal model to identify the neuronal basis of perceptual decision making and the role of context.
The Role Of Corticothalamic Feedback On The Response Dynamics Of Thalamic Neurons

Summary
A fundamental question in neuroscience is how the brain selectively processes sensory information to generate a reliable representation of the world. Positioned in the centre of the brain, the thalamus plays a key role in sensory processing. This project investigates how the interaction between thalamus and cortex shapes the selection and gating of sensory information. This is a fundamental question in basic neuroscience with the potential to increase our knowledge about attentional deficits.
Sudden Cardiac Arrest: Improving Detection Of Patients At Risk

Summary
Sudden cardiac death accounts for ~10% of deaths in our community. Many of these deaths occur in people who could otherwise have had many more years of productive life ahead of them. The aim of our research is to determine the underlying mechanisms so that we can develop better tools for detecting underlying problems before they become life threatening and potentially develop new treatments to modify the underlying causes.
The Structural Basis For Promiscuity Of Drug Binding To HERG K+ Channels

Summary
Special proteins called ion channels control the electrical activity of the heart. Drugs that block ion channels can have the unwanted side-effect of altering the rhythm of the heart beat and causing sudden cardiac death. Extensive efforts are made to screen for this problem during drug development but it is still an inexact science. Here we will use high resolution imaging technologies to get a better understanding of how drugs bind to ion channel proteins.

Summary
Chronic heart failure is a cause of suffering and a major cause of death in the Australian community. Patients who have chronic heart failure suffer from a range of symptoms that severely impacts every aspect of their life. One of the most common and distressing symptoms is breathlessness. As people with heart failure near death, their breathlessness may worsen not only in terms of its frequency, but also in its intensity.

Patients who have chronic heart failure suffer from a range of symptoms that severely impacts every aspect of their life. One of the most common and distressing symptoms is breathlessness. As people with heart failure near death, their breathlessness may worsen not only in terms of its frequency, but also in its intensity. This worsening of symptoms is a source of great distress, both to patients as well as their carers and family. Breathlessness is also the most common cause of admission to hospital for patients. A key strategy for managing this distressing symptom in the home is the supply of oxygen. However, due to a lack of scientific evidence for the benefit of home oxygen for people with heart failure, who do not necessarily have low levels of oxygen, it is very difficult for clinicians to access this therapy for their patients. This study seeks to assess if a specific breathlessness action plan alone or if the addition of either oxygen or air can relieve this distressing symptom. The scientific evaluation of these strategies will assist in improving the palliative care of people with chronic heart failure.Read moreRead less
Deadly Commute - Targeting The Trafficking Mechanisms That Licence Inflammatory Cell Death

Summary
MLKL is a protein naturally found inside cells. MLKL is activated by inflammation. Once activated, MLKL relocates to the outer periphery of cells and kills them. Gut cells are especially vulnerable to death-by-MLKL and this problem causes Inflammatory Bowel Disease. Using cutting edge microscopy, we have discovered how MLKL moves to the periphery of cells prior to killing them. We will test if blocking this movement of MLKL to the cell periphery stops gut death and Inflammatory Bowel Disease.
