Brain research is undoubtedly one of the key research fields today. This project involves highly innovative research at the highest international level, keeping Australia at the forefront of research on brain lateralization, a very important field of brain research in humans and animals (co-founded by the applicant). This project 1) investigates dynamic changes of the developing, mature and ageing brain for vital functions using animal models, thus contributing importantly to our understanding of normal functions of the human brain, including some forms of mental dysfunction and also ageing; 2) trains postgraduate students at the highest standards and 3) maintains important collaboration with colleagues in Europe.

Summary
How do neural circuits coordinate to produce adaptive changes in behaviour? This project aims to discover how neurons alter their function in coordinated ways to produce adaptive changes in behaviour. Behavioural outputs result from the activity of multiple cells in a functional network, but current methods are limited to studying signalling effects on single neurons. To address this, I will develop new methods to visualise every cell in the brain of the living nematode worm to provide a unique ....How do neural circuits coordinate to produce adaptive changes in behaviour? This project aims to discover how neurons alter their function in coordinated ways to produce adaptive changes in behaviour. Behavioural outputs result from the activity of multiple cells in a functional network, but current methods are limited to studying signalling effects on single neurons. To address this, I will develop new methods to visualise every cell in the brain of the living nematode worm to provide a unique systems-level understanding of a model brain. Through collaboration with engineers and psychologists, I will describe molecular switches that trigger reorganisation of entire neural networks. Expected outcomes include new insights on neural circuit plasticity, which will advance discovery in neuroscience and robotics.Read moreRead less
Mechanism of transmission of calcium waves by glial cells. This research concerns determining the fundamental properties of cells that occupy about 70% of the brain, the glial cells. Two very important discoveries on glial cells have recently been made, namely that they can convey information in the form of patterns of waves and that they possess molecules on their surface membranes that have been implicated in psychotic disorders. One such molecule is called the D2 receptor and its malfunctioni ....Mechanism of transmission of calcium waves by glial cells. This research concerns determining the fundamental properties of cells that occupy about 70% of the brain, the glial cells. Two very important discoveries on glial cells have recently been made, namely that they can convey information in the form of patterns of waves and that they possess molecules on their surface membranes that have been implicated in psychotic disorders. One such molecule is called the D2 receptor and its malfunctioning has been implicated in schizophrenia. Our research will determine the way in which information is propagated in the glial system of the brain and also illuminate the function of several of the molecules found on the surface of the glial cells.Read moreRead less
Neuron-microglia signalling mechanisms. This research concerns determining the fundamental mechanisms by which one of the principal non-neuronal cells in the brain , the microglial cell, interacts with neurons to change their properties. The correct functioning of neural networks is necessary for our normal behaviour. Such networks can be disrupted and indeed destroyed by the release of inflammatory molecules from microglial cells. In this work the way in which anti-inflammatory molecules are re ....Neuron-microglia signalling mechanisms. This research concerns determining the fundamental mechanisms by which one of the principal non-neuronal cells in the brain , the microglial cell, interacts with neurons to change their properties. The correct functioning of neural networks is necessary for our normal behaviour. Such networks can be disrupted and indeed destroyed by the release of inflammatory molecules from microglial cells. In this work the way in which anti-inflammatory molecules are released from the microglia will be elucidated, thus providing insight into how to prevent the destructive actions of the inflammatory molecules on the nervous system.

How brains become lateralised. This project aims to understand how the left and right sides of the brain become specialised for different cognitive functions, a phenomenon called lateralisation. Lateralisation is one of the least understood organisational principles of the brain, yet is crucial to the way we think and behave. Manifested most clearly as handedness, the brain is lateralised for many cognitive tasks such as language, reasoning, memory and emotion. However, the developmental origin ....How brains become lateralised. This project aims to understand how the left and right sides of the brain become specialised for different cognitive functions, a phenomenon called lateralisation. Lateralisation is one of the least understood organisational principles of the brain, yet is crucial to the way we think and behave. Manifested most clearly as handedness, the brain is lateralised for many cognitive tasks such as language, reasoning, memory and emotion. However, the developmental origin and anatomical substrate of most cognitive asymmetries are unknown. This project will use a chick model of brain lateralisation to quantify and localise to specific brain circuits the patterns of differential gene expression that give rise to anatomical and functional asymmetries.Read moreRead less
Functional imaging of colour pathways in the living eye. In order to repair or regenerate a diseased eye, we require knowledge of the normal pattern or nerve cell connections, and knowing how biology solves the problem of colour vision can be used to improve the design of artificial vision systems. The adaptive optics machine we will build in this project can be used to image nerve cells, fine blood vessels, and nerve fibre bundles in the normal and diseased eye. This will improve Australia's re ....Functional imaging of colour pathways in the living eye.

The adaptive optics machine we will build in this project can be used to image nerve cells, fine blood vessels, and nerve fibre bundles in the normal and diseased eye. This will improve Australia's research and development capacity in this new area of medical diagnostics. Our machine will be made available to other Australian laboratories and will improve the national capacity for making further scientific discoveries about how the visual system works.Read moreRead less

Understanding gender differences in pain: Cellular therapies for animal pain. This project aims to relieve chronic pain in animals and lay the foundations for future human therapies, using molecular assays, cell technologies and immune/hormonal pain generators. Chronic pain affects females more than males. Establishing the fundamental mechanism in pain, the role of immune signalling and molecular mediators will enable true pain-modifying treatments that address pivotal triggers in both genders. This project will then use specially selected stem cells separately targeting arthritic male and female pain and demonstrate novel veterinary chronic pain treatments. Expected outcomes are more effective gender-targeted treatments of pain and the realisation of economic value of molecular assays and cell technologies.Read moreRead less

Our project will study the conditions under which normally altruistic honeybee workers parasitise other colonies. Thus we will explore a fundamental question: how is the expression of selfish behaviour normally controlled? Outcomes of this project will be important to our understanding of insect societies but will also have application for those studying the development of tumours in multicellular organisms, the development of metazoan bodies, and social cohesion in human and non-human societies. Our project will also help protect Australia's honey industry from the devastating social parasites that have ruined the industry in South Africa.Read moreRead less
Calcium Signalling and Sequestration at Vertebrate Motor-Nerve Terminals. A fundamental process at Synapses is the release of transmitter from nerve terminals due to the initiation of calcium signalling in the temrinals by impulses. This calcium signalling must be terminated by sequestering processes.

A fundamental process at Synapses is the release of transmitter from nerve terminals due to the initiation of calcium signalling in the temrinals by impulses. This calcium signalling must be terminated by sequestering processes. The aim of this project is to identify these processes in a vertebrate motor-nerve terminal and to determine the means by which calcium signals the changes in efficacy of transmitter release during trains of impulses. This work will give a complete description of calcium signalling in a vertebrate nerve terminal and provide the basis for ameliorating failures in transmission from nerve to muscle.Read moreRead less
