Plasticity of gastrointestinal vagal afferents. The aim of this project is to identify how leptin modulates specific subtypes of vagal afferent within the gut and the plasticity of this system under different dietary conditions. This proposed project will substantially increase understanding of the interactions between leptin, known to influence food intake, and vagal afferent satiety signals. It will also increase understanding of how these interactions alter in obesity and ultimately provide t ....Plasticity of gastrointestinal vagal afferents.

How does timing affect mammalian brain development and evolution? This project aims to generate fundamental knowledge on the origin of diversity in mammalian brain circuits by studying development of marsupials and rodents. The expected outcome is to elucidate how differences in the timing, rate and sequence of development of gene expression, cell differentiation and circuit formation can relate to the origin of key evolutionary innovations in the mammalian brain. The significance of understandi ....How does timing affect mammalian brain development and evolution? This project aims to generate fundamental knowledge on the origin of diversity in mammalian brain circuits by studying development of marsupials and rodents. The expected outcome is to elucidate how differences in the timing, rate and sequence of development of gene expression, cell differentiation and circuit formation can relate to the origin of key evolutionary innovations in the mammalian brain. The significance of understanding the dynamics of developmental systems that shape complex brain traits includes establishing new developmental paradigms in evolutionary theory, generating new tools to investigate and manipulate brain gene expression in vivo, and the potential discovery of the causes of neurodevelopmental dysfunction.Read moreRead less
Using the eye as a window to the central nervous system for improved drug testing. The annual cost of treating brain illnesses is US$250 billion. Each new drug costs about US$900 million to develop. This research will give Pfizer Pty Ltd, the project’s industry partner, a more efficient and direct way of testing whether drugs can get into and affect the brain. This will reduce the cost of drug development, which ultimately means cheaper drugs. The project will develop new technologies to put Aus ....Using the eye as a window to the central nervous system for improved drug testing.

This will reduce the cost of drug development, which ultimately means cheaper drugs. The project will develop new technologies to put Australia at the forefront of neuropharmaceutical and neuroscience research. A new research platform will foster collaborations with the pharmaceutical industry both within Australia and overseas. This industrial link will promote a unique post-graduate experience by providing exposure to academic and industrial environments for Australian scientists.Read moreRead less
Microtubule structure in nervous system repair. This Project aims to investigate the role of structural and functional cellular components known as microtubules in nervous system regeneration.

This Project aims to investigate the role of structural and functional cellular components known as microtubules in nervous system regeneration. This Project aims to use innovative approaches in confocal and electron microscopy, genetics, and cell biology, with the expectation of generating new knowledge into nervous system repair. Expected outcomes of this Project include a comprehensive description of how microtubules are rearranged following nervous system injury and the importance of microtubule modifying proteins in promoting regeneration. This should provide significant benefits in our understanding of the cellular mechanisms behind nervous system repair, and offer new approaches for promoting regeneration after injury.Read moreRead less
Early formation of the preplate establishes the cerebral cortex. The cerebral cortex is arguably the most complex area of the brain due to its ability to process and integrate a wide variety of information in a seamless manner. To understand how this occurs, it is essential to understand how the cerebral cortex is built during embryonic life. The focus of this project is on the formation of the very earliest neurons of the cortex, called preplate neurons. This project aims to: test a new model f ....Early formation of the preplate establishes the cerebral cortex.

To understand how this occurs, it is essential to understand how the cerebral cortex is built during embryonic life. The focus of this project is on the formation of the very earliest neurons of the cortex, called preplate neurons. This project aims to: test a new model for preplate development with regards to their origin; their function in formation of the cerebral cortex; and the the molecular mechanisms underlying their development. This work provides a developmental framework for understanding how the cerebral cortex is established.Read moreRead less
The Neural Bases of Decision-Making. The smooth integration of cognitive and emotional processes is necessary for everyday decisions. Dysfunction in this integrative capacity accompanies dementia, neurodegenerative conditions and major psychiatric disorders.

The smooth integration of cognitive and emotional processes is necessary for everyday decisions. Dysfunction in this integrative capacity accompanies dementia, neurodegenerative conditions and major psychiatric disorders. This project seeks to understand the neural bases of this integration in normal decision-making using cutting edge behavioural, cellular, molecular and genetic tools to map the neural system, circuit and cellular processes controlling the selection, evaluation and choice of goal-directed actions. Such actions can, with continued practice, transition into relatively inflexible habits. Thus, this project aims to investigate the neural processes that mediate this transition and how actions and habits interact in normal decision-making.Read moreRead less

This project aims to investigate the neural bases of behaviour in the mammalian gut. The Enteric Nervous System (ENS) plays a critical role in the propulsion of intestinal contents. This project expects to establish how specific functional classes of enteric neurons control propulsion along the gut. By recording the simultaneous neural activity from hundreds of different functional classes of enteric nerve cells simultaneously, whilst recording intestinal muscle electrical activity and the movements of the gut wall, the project expects to identify which enteric neurochemical classes of neurons generate specific motor patterns along the intestine.Read moreRead less
Investigating the role of the innate immune complement system in the abnormal development of the central nervous system. Past research has discovered a surprising link between the immune system, dietary folate deficiency and the development of the embryonic brain. This project will investigate the immune system in the developing brain, in order to understand the causes of developmental defects such as neural tube defects, and the role dietary folate plays in this process.

This project aims to better understand the biology and functioning of the nervous system using an innovative multi-disciplinary approach informed by the rabies virus. The study intends to identify the molecular mechanism responsible for self-destruction in neurons. The project aims to gain this new knowledge by investigating the novel natural ability of rabies virus to subdue self-destruction mechanism in neurons. The principal benefit is the gain of detailed knowledge about a fundamental biological mechanism at the intersection of neurobiology and virology. This has the potential to inform future research in areas such as the maintenance of neuronal health in ageing and better control of rabies infections. Read moreRead less
Investigating the neuroprotective actions of metallo-complexes. Metal-based drugs offer an exciting new approach to treatment of neurodegeneration. However, little is known about how cells metabolise these drugs: information that is critical for further drug development. This project will determine how metal-based drugs are metabolized by neuronal cells and how this may result in therapeutic benefit.
