LIM-homeodomain interactions in neuronal development. The loss of central nervous system function, through accident or disease, is devastating for affected individuals and their families. Our current inability to stimulate the regeneration of nervous tissue is a result of the lack of detailed knowledge of the complex processes that must take place, at the molecular and cellular levels, during neuronal development.

The loss of central nervous system function, through accident or disease, is devastating for affected individuals and their families. Our current inability to stimulate the regeneration of nervous tissue is a result of the lack of detailed knowledge of the complex processes that must take place, at the molecular and cellular levels, during neuronal development. We are determining how a group of cellular proteins that have key roles in motor neuron development interact with each other and with DNA. With this information we are developing reagents that can be used to further probe central nervous system function and may ultimately be used to regenerate damaged nerves.Read moreRead less
Cellular Plasticity in the Brain: discovering molecular mechanisms controlling the production of neurons during brain development, function, ageing and disease. The program aims to understand the mechanisms regulating Brain Plasticity - this recently discovered property of the brain to respond to environmental stimuli, both physiological and pathological, by producing new functional neurons. Specifically, the program will discover how the brain's stem cells are stimulated to produce new neurons. ....Cellular Plasticity in the Brain: discovering molecular mechanisms controlling the production of neurons during brain development, function, ageing and disease. The program aims to understand the mechanisms regulating Brain Plasticity - this recently discovered property of the brain to respond to environmental stimuli, both physiological and pathological, by producing new functional neurons. Specifically, the program will discover how the brain's stem cells are stimulated to produce new neurons. This understanding will significantly expand our knowledge of how the brain develops, and how functions, like memory, are modulated by neuronal replacement. Discoveries will underpin the development of, in association with Australia's biotechnology sector, a new generation of therapeutics, which treat neurological diseases, like Stroke, by stimulating the production of functional neurons.Read moreRead less

The outcomes of this project will increase the understanding of how nerve cells develop and regenerate after injury. The research outcomes and the development of new innovative methodologies as part of the project will be of high significance for the neuroscience research community both within Australia and overseas. The findings will also pave the way for the development of ....Understanding how the multiple roles of olfactory ensheathing cells guide the growth and regeneration of olfactory axons. The outcomes of this project will increase the understanding of how nerve cells develop and regenerate after injury. The research outcomes and the development of new innovative methodologies as part of the project will be of high significance for the neuroscience research community both within Australia and overseas. The findings will also pave the way for the development of novel therapies that promote neuronal regeneration relevant for disorders such as spinal cord injury and Alzheimer's disease, which constitute a large socio-economic burden in Australia. Currently, 400 people contract spinal cord injury every year, corresponding to an annual cost of $1 billion, and more than 500 000 aging people suffer from Alzheimer's disease.Read moreRead less

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

Summary
Clinical obstetric and paediatric studies have identified an association between intrauterine infection occurring around two thirds of the way through pregnancy, premature birth and a specific form of damage to the brain of the newborn. This damage mainly affects white matter tracts. These tracts are aggregations of nerve fibres that make the connections between different parts of the brain and may result in cerebral palsy or other neurological disorders.

This damage mainly affects white matter tracts. These tracts are aggregations of nerve fibres that make the connections between different parts of the brain and may result in cerebral palsy or other neurological disorders. The association between maternal infection and brain damage, one form of which is cerebral palsy, is well established from clinical epidemiological studies, but the biological mechanism of this link is unknown. The CIs' group has recently shown that the condition can be reproduced in neonatal rats at a stage of brain development in the rat that is equivalent to the critical time in human brain development when infection may be associated with brain damage. The CIs' group has shown that an induced inflammatory state similar to a bacterial infection, results in damage to blood vessels in the white matter and is associated with changes in white matter, as occurs in affected babies. The purpose of this study is to understand the nature of the damage to white matter blood vessels and the mechanisms by which materials in blood, which in the normal brain do not pass from the blood to the brain across the blood-brain barrier, are able to do so via the inflammation damaged blood vessels. The study also aims to show whether it is components of the blood entering the brain via the damaged blood vessels that are responsible for the damage to white matter in the immature brain. The outcome should lead to development of ways to improve clinical care of women who acquire infections during pregnancy.Read moreRead less
What shapes our brain? This project aims to improve our fundamental understanding of the biological mechanisms that drive folding of the cerebral cortex, which occurs during development of the brain. Cortical folding is unique to humans and higher mammals, and is thought to underpin the emergence of intelligence and contribute to higher-order brain functions. This project will enhance knowledge of how the cerebral cortex folds and develop novel tools for analysing brain development. The project ....What shapes our brain? This project aims to improve our fundamental understanding of the biological mechanisms that drive folding of the cerebral cortex, which occurs during development of the brain. Cortical folding is unique to humans and higher mammals, and is thought to underpin the emergence of intelligence and contribute to higher-order brain functions. This project will enhance knowledge of how the cerebral cortex folds and develop novel tools for analysing brain development. The project will provide significant benefits including the generation of fundamental knowledge with implications for future understanding of cortical folding abnormalities in babies born preterm, following fetal growth retardation in utero, or when exposed to maternal alcohol. In the longer term, the project will contribute to improvements to human neurodevelopment and brain health.Read moreRead less

proposal will establish models of 4 key stages. Employing innovative, interdisciplinary approaches, biomaterials will be fabricated to provide structural and chemical support for human stem cells during: (i) neural induction, (ii) specification into neuronal progenitor subpopulations, (iii) neuronal maturation and integration into complex neural networks as well as, (iv) the organisation of neurons into larger 3-dimensional brain structures, namely folding of the human cortex. Further, biomaterials developed here have commercialisation potential, targeted at standardizing the culturing of human stem cells to defined neural populations.
