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
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.

Rhombomeric Topography of Structures in the Adult Mouse: Evidence from Avian Homologies and Transgenic Mice. The brainstem of birds has been shown to be formed by a line of segments, like carriages of a train. The same arrangement exists in the embryos of mammals, but is hidden in the adult mammalian brain. We will transfer our detailed knowledge of bird brains to make a maps of the brainstem segments in adult mice. We will then test this map with special gene markers which will reveal the occul ....Rhombomeric Topography of Structures in the Adult Mouse: Evidence from Avian Homologies and Transgenic Mice. The brainstem of birds has been shown to be formed by a line of segments, like carriages of a train. The same arrangement exists in the embryos of mammals, but is hidden in the adult mammalian brain. We will transfer our detailed knowledge of bird brains to make a maps of the brainstem segments in adult mice. We will then test this map with special gene markers which will reveal the occult segmental pattern in adult mice. This work will give us a new way of understanding the organisation of brainstem centres that control breathing, cardiovascular functions and emotional states.Read moreRead less
INVESTIGATION OF A BRAIN RHYTHM. Elucidation of brain function remains a frontier for human discovery. To date, research has largely focussed on brain connectivity with major advances in knowledge of input/output function of brain regions. Yet, there remains little understanding of higher order processes that underlie functions such as mood states and consciousness. Investigation of brain rhythms represent a step to unravelling such processes, as rhythms both act as autonomous clocks and generat ....INVESTIGATION OF A BRAIN RHYTHM. Elucidation of brain function remains a frontier for human discovery. To date, research has largely focussed on brain connectivity with major advances in knowledge of input/output function of brain regions. Yet, there remains little understanding of higher order processes that underlie functions such as mood states and consciousness. Investigation of brain rhythms represent a step to unravelling such processes, as rhythms both act as autonomous clocks and generate synchronised neuronal activity. This project aims to investigate mechanisms underlying a specific class of brain rhythm implicated in control of mood states. Positive outcomes from this basic research may lead to better drug therapies for controlling specific mental disorders.Read moreRead less

The neural bases of decision-making. This research focuses on the neural bases of decision making, a general capacity affected by normal ageing, disorders associated with neurodegeneration including dementia, major psychiatric conditions and drug addiction. Changes in the neural systems that result in the cognitive and emotional dissociation reflected in these disorders constitute the highest health, economic and social capital attrition burden to Australia of any disease group, a burden that is ....The neural bases of decision-making. This research focuses on the neural bases of decision making, a general capacity affected by normal ageing, disorders associated with neurodegeneration including dementia, major psychiatric conditions and drug addiction. Changes in the neural systems that result in the cognitive and emotional dissociation reflected in these disorders constitute the highest health, economic and social capital attrition burden to Australia of any disease group, a burden that is only predicted to increase as the population ages. Understanding these changes in neural systems and their specific behavioural effects is, therefore, of critical importance and will ultimately provide new targets for treatment and rehabilitation.Read moreRead less
Unraveling the role of N-acetyl-aspartate in normal brain function and disease. The purpose of this project is to define the role of the predominating brain chemical N-acetyl-aspartate for normal nerve cell function and as toxic agent causing neurological illness and severe mental health problems. Findings of this research will enhance the design of novel therapies involving pharmacological and genetic treatment.

Microglia and the inflammation spectrum - not just good or bad. Cell-mediated tissue clearance following brain injury is a universal mechanism. However, our understanding of the cells that perform these tasks is very limited.

Our project will characterise this inflammatory response at a single-cell level using the zebrafish spinal cord as a versatile experimental model. The project is expected to strongly contribute to the molecular understanding of the mechanisms underlying debris removal and will advance innovative technologies that facilitate intellectual progress in neuroscience. It will produce new insights into the process of neuronal degeneration, promote Australia’s growing reputation as a global leader in neuroscience, and provide high quality training for early career researchers.Read moreRead less

Attention-deficit/Hyperactivity Disorder (AD/HD) is the most common psychiatric disorder affecting children, resulting in substantial costs (both human and financial) to the child, their family and Australian society. The outcomes of this project will provide a better foundation for understanding dysfunctional brain mechanisms in AD/HD, which is expected to lead to better diagnosis, treatment, and community support. Ultimately this will contribute to a healthy start to life for these children. This project will also demonstrate how an integrated Australian approach can lead the research agenda in both basic neuroscience, at the interface of psychology and physiology, and its applications in health.Read moreRead less
