Neural plasticity in older adult human vision. This project aims to expand our understanding of age related changes in brain function, specifically plasticity. The project will increase knowledge of the role of an inhibitory neurotransmitter GABA in visual plasticity. Expected outcomes include new knowledge regarding the regulation of brain function in adulthood, enabling future research and planning for societal benefit to older Australia.
Future neural electrodes: probing the electrical activity of nerves using 3D graphene networks. This research aims to develop a totally new type of neural electrode that will for the first time, allow reliable and long-term stimulation and recording. The approach incorporates graphene based biomaterials with tunable electrical and biological properties within supportive three-dimensional cellular microenvironments, greatly enhancing the electrical interactions between cells and the electrode.

The approach incorporates graphene based biomaterials with tunable electrical and biological properties within supportive three-dimensional cellular microenvironments, greatly enhancing the electrical interactions between cells and the electrode. The electrical properties of nerve cells will be probed using our three-dimensional graphene network, providing insight into the the brain-machine interface. This project is important as it directly addresses the inherent limitations of current electrode designs.Read moreRead less
Using visual science to reduce the dangers of night driving. This project aims to develop novel tests of visual function relevant to the modern night driving environment. Night driving is challenging for all drivers and has been linked to poor visibility under low light conditions. This project will characterise the visual challenges of the modern night driving environment, develop visual tests that incorporate the dynamic light levels typical of night-time roads and assess the association of th ....Using visual science to reduce the dangers of night driving. This project aims to develop novel tests of visual function relevant to the modern night driving environment. Night driving is challenging for all drivers and has been linked to poor visibility under low light conditions. This project will characterise the visual challenges of the modern night driving environment, develop visual tests that incorporate the dynamic light levels typical of night-time roads and assess the association of these tests with night driving performance. The outcomes will contribute new knowledge regarding dynamic visual processing and the ageing visual system and will inform vision testing, potential interventions to improve visual function for night driving and reduce the dangers of night driving.Read moreRead less
Improved effectiveness of cochlear implants through new simultaneous stimulation techniques. Cochlear implants have brought the gift of hearing to 250,000 people worldwide and are an excellent example of Australian innovation. This project will examine an improved "high fidelity" stimulation strategy with the objective of defining a safe stimulus range for clinical use and providing a commercial advantage for Cochlear Ltd.
Specification of the nerve cell subtypes in the developing central nervous system. Different subtypes of nerve cells in the brain, which carry out distinct functions, are generated in the embryo by the co-ordinated action of many genes. This project aims to use the genetic advantages of the zebrafish to determine the role of genes in specifying the final fates of nerve cells in the retina, which analyses visual signals within the eye.

Summary
Role of intrinsic versus extrinsic cues in cell type determination during development and regeneration. During development all of the different cell types are generated by the action of genes and also signals from the embryo that read out which cell types are present or missing. This project studies how much environmental signals affect cell type generation developmentally and if they can be used to regenerate only the types missing in different diseases.
Novel mechanisms for regulating the retinal vasculature. Tight control of the retinal vasculature is crucial for maintaining normal vision. Unlike most blood vessels in the body, those in the retina and brain receive no direct neural control. Rather they rely on support cells to communicate the needs of neurons. This project aims to examine the mechanisms by which resident immune cells, called microglia, regulate retinal capillaries in response to neural activity. New knowledge examining a novel ....Novel mechanisms for regulating the retinal vasculature. Tight control of the retinal vasculature is crucial for maintaining normal vision. Unlike most blood vessels in the body, those in the retina and brain receive no direct neural control. Rather they rely on support cells to communicate the needs of neurons. This project aims to examine the mechanisms by which resident immune cells, called microglia, regulate retinal capillaries in response to neural activity. New knowledge examining a novel mechanism will be generated. This information is crucial for enhancing our understanding of how blood vessels are controlled in the retina and brain and will guide the development of novel ways of examining blood vessel function.Read moreRead less
Exploiting high resolution images of the retina to customise vision tests. This project will make vision tests more accurate and faster by using a person's individual eye anatomy to customise the test. The basic understandings discovered in this project are expected to be applied in clinical and research settings thus saving sight, dollars and time.
New, Efficient Tests That Map Both Central and Peripheral Vision. This project seeks to develop a new, combined approach for quantifying both central and peripheral vision with a single test. Current methods for testing far peripheral vision are not efficient and not fully automated. Yet peripheral vision is important for tasks involving navigation and hazard avoidance such as driving. The project intends to invent and test new approaches to sampling and measuring the spatial extent of vision. T ....New, Efficient Tests That Map Both Central and Peripheral Vision. This project seeks to develop a new, combined approach for quantifying both central and peripheral vision with a single test. Current methods for testing far peripheral vision are not efficient and not fully automated. Yet peripheral vision is important for tasks involving navigation and hazard avoidance such as driving. The project intends to invent and test new approaches to sampling and measuring the spatial extent of vision. The anticipated algorithms will be more accurate and efficient than current tests, will be suitable for older adults, and will enable ready assessment of vision for occupational tasks.Read moreRead less
