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
How the brain regulates blood pressure. This project will test whether a group of nerve cells in the rostral ventrolateral medulla generate sympathetic activity in blood vessels. The brain regulates blood pressure through several pathways, including nerves in the sympathetic nervous system that constrict blood vessels and increase the heart rate. Activity of these sympathetic nerves regulates blood pressure, but it is unknown which nerve cells in the brain cause this activity. This information i ....How the brain regulates blood pressure. This project will test whether a group of nerve cells in the rostral ventrolateral medulla generate sympathetic activity in blood vessels. The brain regulates blood pressure through several pathways, including nerves in the sympathetic nervous system that constrict blood vessels and increase the heart rate. Activity of these sympathetic nerves regulates blood pressure, but it is unknown which nerve cells in the brain cause this activity. This information is essential to understand how blood pressure is controlled under healthy conditions.Read moreRead less
Brain sodium channel: functional role of developmentally regulated alternative splicing. This project will identify the roles of neonatal and adult forms of a sodium channel in the function of neurons in the developing brain. Sodium channels are vital for brain function and this study will improve our understanding of the function of healthy brain as well as of underlying mechanisms of some neurological disorders.
Sustaining neuronal communication through bulk endocytosis. Brain activities such as learning and memory rely on the ability of neurons to communicate. This research will improve our understanding of how synaptic vesicles recycle during periods of intense synaptic activity. This is a fundamental process relevant to neuronal communication, insulin release, hormone secretion, and allergic responses in health and disease and therefore has broad significance. This work will enhance Australia's exist ....Sustaining neuronal communication through bulk endocytosis. Brain activities such as learning and memory rely on the ability of neurons to communicate. This research will improve our understanding of how synaptic vesicles recycle during periods of intense synaptic activity. This is a fundamental process relevant to neuronal communication, insulin release, hormone secretion, and allergic responses in health and disease and therefore has broad significance. This work will enhance Australia's existing strength in cell biology and neuroscience and provide high quality training for an undergraduate student and post-doctoral scientist.Read moreRead less
Gene-environment interactions mediating experience-dependent plasticity in the healthy and diseased brain. The aim of this project is to understand how genes and environment combine to affect susceptibility to various brain disorders, using models of human diseases and manipulating environmental factors such as mental and physical activity. The project's focus is on neurological and psychiatric disorders, including Huntington's disease, depression, schizophrenia and autism.
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.
Increasing the utility of tetanus toxins by protein engineering. There are a variety of common diseases that are the result of muscular defects. Some of these may be able to be treated with an agent that increases muscle tone, thereby giving benefit to the patient in the alleviation of symptoms. This project aims to use some of the most potent substances known, bacterial toxins, and engineer them to be valuable agents for treatment of certain muscular disorders.
Identifying genes that influence clinical course and susceptibility in multiple sclerosis. This project aims to identify the genetic basis of multiple sclerosis (MS), the most common neurologic disease in young Australian adults. MS urgently needs research to identify predisposition, aid early diagnosis and provide bona fide molecular targets for new therapies. This will benefit people with MS and those susceptible to it. Crucial new knowledge identified will benefit other major areas of MS rese ....Identifying genes that influence clinical course and susceptibility in multiple sclerosis. This project aims to identify the genetic basis of multiple sclerosis (MS), the most common neurologic disease in young Australian adults. MS urgently needs research to identify predisposition, aid early diagnosis and provide bona fide molecular targets for new therapies. This will benefit people with MS and those susceptible to it. Crucial new knowledge identified will benefit other major areas of MS research including epidemiology, immunology and neurobiology. Collaboration of 8 major Australian institutions is also important for this project and future studies. The team will have access to a new national MS GeneBank (platform) with samples from 2240 patients that should generate findings important to world-wide MS genetic knowledge.Read moreRead less
The Genetic Analysis of Neurological Diseases. Multiple sclerosis and Parkinson's are debilitating neurodegenerative diseases, which affect 16,000 and 80,000 Australians, respectively. Between them, these diseases cost the community $7.8 billion per annum, and there is no cure. This proposal will study the genes that influence a person's predisposition to developing these diseases, and what makes some people have particular characteristics. It will provide novel insights into the diseases themse ....The Genetic Analysis of Neurological Diseases. Multiple sclerosis and Parkinson's are debilitating neurodegenerative diseases, which affect 16,000 and 80,000 Australians, respectively. Between them, these diseases cost the community $7.8 billion per annum, and there is no cure. This proposal will study the genes that influence a person's predisposition to developing these diseases, and what makes some people have particular characteristics. It will provide novel insights into the diseases themselves and information that could help in the development of new and more effective drugs, and biomarkers to assist in the prediction of prognosis. Such advances would decrease the economic impact of these diseases and improve quality of life for those affected.Read moreRead less

Investigating novel neurobiological mechanisms in rabies infection. 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.

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
