Mechanisms of itch - from endosomal signalling to neural circuits. This project aims to investigate the cellular and circuit mechanisms of itch transmission in the spinal cord by defining the activation and propagation of itch-specific signals. This project expects to generate new knowledge in the area of neuronal signalling and circuitry using novel electrophysiological approaches that target and manipulate specific nerves and cellular components. The project will characterise signalling within ....Mechanisms of itch - from endosomal signalling to neural circuits. This project aims to investigate the cellular and circuit mechanisms of itch transmission in the spinal cord by defining the activation and propagation of itch-specific signals. This project expects to generate new knowledge in the area of neuronal signalling and circuitry using novel electrophysiological approaches that target and manipulate specific nerves and cellular components. The project will characterise signalling within specific spinal subcircuits in order to understand the mechanisms of receptor activation and signalling, and investigate how circuit activity is regulated. This project expects to advance fundamental understanding of itch signalling in the nervous system and provide avenues for future therapeutics.Read moreRead less
Understanding the changes in brain chemistry associated with schizophrenia. Current drugs for schizophrenia only work in 30% of patients. To develop better therapies, we must understand the changes in the brains of people with the disorder. This research will explore a chemical system in the brain that is changed in schizophrenia and begin to investigate whether counteracting these changes are therapeutically beneficial.
Neural Control Of Behavioural State And Cognition - Role Of Nucleus Incertus And Relaxin-3

Summary
Dementia and mental illness are significant social and economic burdens worldwide and knowledge of underlying causes and more effective therapies are required. Our research is using preclinical models to characterize a little studied neural network in the control of arousal states, rhythmic brain activity, and learning and memory. Our findings could advance the development of improved treatments for cognitive deficits in degenerative, age-related and psychiatric disorders.

Summary
Mental illness is a significant social and economic burden worldwide and knowledge of the underlying causes and more effective therapies are required. Our research aims to use pre-clinical animal models to characterize a little studied brain neuronal network implicated in control of arousal and stress, which could lead to improved treatment of psychiatric disorders such as depression.
Delineating the functional role of the amyloid precursor protein's copper binding domain. This study will define how the interaction between copper and the amyloid precursor protein (APP) molecule regulates copper homeostasis and APP metabolism. Since copper homeostasis is tightly regulated and vital for normal cellular function, understanding the regulation copper homeostasis is important for basic biology. Moreover, APP is directly involved in causing Alzheimer's disease and therefore underst ....Delineating the functional role of the amyloid precursor protein's copper binding domain. This study will define how the interaction between copper and the amyloid precursor protein (APP) molecule regulates copper homeostasis and APP metabolism. Since copper homeostasis is tightly regulated and vital for normal cellular function, understanding the regulation copper homeostasis is important for basic biology. Moreover, APP is directly involved in causing Alzheimer's disease and therefore understanding the interaction between APP and copper has potential benefits for community health by combating aging and Alzheimer's disease.Read moreRead less
The role of P2X7 and P2X4 receptor mediated innate phagocytosis in pathogenesis and treatment of neurodegenerative diseases. This project will identify how inherited variation in two proteins of the brain can accelerate the removal of neurones and predispose to a range of neurodegenerative diseases. Knowledge of the biological basis of this finding will allow a search for new compounds which will slow and protect against this form of neurodegeneration.

Brain and Behaviour Network. The Brain and Behaviour Network is concerned with understanding the underlying mechanisms which determine how we behave. It encompasses many disciplines including anthropology, education, ethology, neurology, neuroscience, philosophy and psychology. The Network will bring these disciplines together to create a forum to discuss and integrate the knowledge into a framework for understanding the mechanisms of behaviour and to stimulate cross-disciplinary research.

It encompasses many disciplines including anthropology, education, ethology, neurology, neuroscience, philosophy and psychology. The Network will bring these disciplines together to create a forum to discuss and integrate the knowledge into a framework for understanding the mechanisms of behaviour and to stimulate cross-disciplinary research. The framework of knowledge will lead to a greater understanding of how we behave and will improve knowledge in areas which have a major behavioural component, such as in human development and education, psychological well-being, psychiatric problems and ageing.Read moreRead less
Resolving the Structures of Human Muscarinic M1 and M4 Receptors. Muscarinic receptors are vital for most basic human brain functions. These receptors are changed in schizophrenia and Alzheimer's disease. This project will determine the structure and localisation of two of these receptors in order to i) understand their roles in brain disorders and ii) develop drugs to treat disorders involving them.
Targeting Necroptosis Signalling To Counter Stroke-induced Brain Injury

Summary
The origins of the brain injury that arises from stroke remain a matter of enormous interest. Our work suggests that a poorly understood form of cell death, termed necroptosis, contributes to injury to the brain following stroke. In addition to developing an advanced understanding of this process, we will use drugs developed at the Walter and Eliza Hall Institute to test whether blocking this process might be a plausible therapeutic strategy in stroke patients.
A toxic cycle of inflammation and iron in the ageing brain. This project investigates why our brain cells gradually die as we grow older. We believe that infections and inflammation in other parts of the body cause iron to accumulate in the brain and become toxic. Iron supplements and ageing may make this situation worse. The results of this study could lead to new treatments for memory loss and dementia.
