Improving neuronal cell function with cell permeable copper complexes. Metal-based drugs offer an exciting new approach to treatment of neurodegeneration. However, little is known about how cells metabolise these drugs and this information is critical for further drug development. This project will determine how metal-based drugs are metabolised by neuronal cells and how this may result in therapeutic benefit.
Suction pipette measurements of mammalian rod photoreceptor recovery following intense bleaching exposures. The aim of this project is to discover the events and processes that prevent retinal photoreceptors from recovering instantaneously following the cessation of exposure to extremely bright illumination. Recordings will be made from single rod photoreceptors cells isolated from the mammalian retina. The work will uncover the relative roles of the 'photoproducts' created when rhodopsin abso ....Suction pipette measurements of mammalian rod photoreceptor recovery following intense bleaching exposures. The aim of this project is to discover the events and processes that prevent retinal photoreceptors from recovering instantaneously following the cessation of exposure to extremely bright illumination. Recordings will be made from single rod photoreceptors cells isolated from the mammalian retina. The work will uncover the relative roles of the 'photoproducts' created when rhodopsin absorbs light: e.g. intermediates such as metarhodopsin and opsin. The molecular knowledge obtained will help us to understand why it is that the visual system recovers so slowly after the eye has experienced very intense light.Read moreRead less
The first stage of vision: transduction and adaptation in retinal photoreceptors. The project aims to provide a detailed understanding of the molecular steps involved in the first stage of vision - the conversion of light into a neural signal in the rod and cone photoreceptors of the retina. The significance of this is that it will explain the initial events that enable us to see, and will help explain the deficits that occur when the process fails. The outcome will be a comprehensive understand ....The first stage of vision: transduction and adaptation in retinal photoreceptors. The project aims to provide a detailed understanding of the molecular steps involved in the first stage of vision - the conversion of light into a neural signal in the rod and cone photoreceptors of the retina. The significance of this is that it will explain the initial events that enable us to see, and will help explain the deficits that occur when the process fails. The outcome will be a comprehensive understanding of how our photoreceptors respond with extreme sensitivity, yet great rapidity, and over an enormous range of light intensities, thus endowing us with our remarkable sense of vision.Read moreRead less
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
Complex Motion Processing in Primate Visual Cortex. As we move through the world, a dynamic visual image is projected onto our retinas. The pattern of movement in the retinal image contains information about three-dimensional structure in the environment and the time of impending collisions. Our visual systems are expert at exploiting this information, enabling us to navigate through complex visual environments at a level far beyond the most sophisticated artificial systems. We plan to investiga ....Complex Motion Processing in Primate Visual Cortex. As we move through the world, a dynamic visual image is projected onto our retinas. The pattern of movement in the retinal image contains information about three-dimensional structure in the environment and the time of impending collisions. Our visual systems are expert at exploiting this information, enabling us to navigate through complex visual environments at a level far beyond the most sophisticated artificial systems. We plan to investigate complex motion processing in the primate brain by recording the responses of neurons in identified regions of the visual cortex of macaque monkeys to a range of behaviourally relevant motion stimuli.Read moreRead less
ARC Centre of Excellence - Vision Science. This Centre will generate important new knowledge of the performance, logic and stability of vision and visual behaviour. This knowledge will help reduce the burden of vision impairment in Australia, increasing productivity, promoting healthy ageing and reducing the community costs of visual impairment (ca. $9.85 billion in 2004). The knowledge produced will also make possible world-class innovations in robotics, leading to novel automated vision system ....ARC Centre of Excellence - Vision Science.

Summary
Establishment of a confocal/multiphoton microscope for imaging of living systems. This facility will allow us to study the dynamic changes in living systems, from the smallest unicellular organisms in the ocean through to the sophisticated neural networks of the living brain. Not only will this imaging facility allow us to understand how living systems work, we will also be able to explore the dynamic changes that underlie human disease and injury.
Resolving the Structures of Human Muscarinic M1 and M4 Receptors. Muscarinic receptors are vital for most basic human brain functions. These receptors are changed in schizophrenia and Alzheimer's disease. This project will determine the structure and localisation of two of these receptors in order to i) understand their roles in brain disorders and ii) develop drugs to treat disorders involving them.
