Summary
The importance of glia in the development of healthy blood vessels in the eye. The formation of healthy blood vessels in the eye is critical for vision. An important peptide in blood vessel formation throughout the body, including the eye, is Angiotensin II. Specific retinal cells named astrocytes and microglia are suggested to be involved in vessel formation. However, the way these cells control this formation is unknown. Using innovative techniques, this project will investigate how retinal as ....The importance of glia in the development of healthy blood vessels in the eye. The formation of healthy blood vessels in the eye is critical for vision. An important peptide in blood vessel formation throughout the body, including the eye, is Angiotensin II. Specific retinal cells named astrocytes and microglia are suggested to be involved in vessel formation. However, the way these cells control this formation is unknown. Using innovative techniques, this project will investigate how retinal astrocytes and microglia control glial-vascular communication and blood vessel formation via Angiotensin II. The information gained from this proposal is critical to our understanding of both normal retinal development and blood vessel maintenance in both infants and those of older ages.Read moreRead less

Explainability and Transparency are the key values for development and deployment of Artificial Intelligence (AI) in Australia’s AI Ethics Framework for industry and governments. This project aims to build new tools to make the central technology of AI - deep learning - transparent and explainable. Its expected outputs are novel theory-driven algorithms and unconventional foundational blocks for deep learning that will allow humans to clearly interpret the reasoning process of this technology, which is currently not possible. It is expected to significantly advance our knowledge in machine intelligence and perception. Due to their fundamental nature, the project outcomes are likely to benefit industry and scientific frontiers alike.Read moreRead less

Summary
Functional imaging with cellular resolution in the living eye. Adaptive optics allows the visualisation of individual cells and capillaries in the living human eye. This project will use adaptive optics to explore the normal function of these microscopic objects, and how this function changes in eyes suffering from disease. This will aid in developing new ways to diagnose and treat debilitating eye diseases.
Wiring the retina for human vision - a single-cell behavioural approach. This project aims to combine optical and behavioural methods to explore how colour information is channelled from individual cone photoreceptors through the living human retina, to the brain. By non-invasively stimulating either a single cell or specific arrangements of cells, the project aims to contribute fundamental knowledge about how the retina is wired to inform our exquisite sense of colour and spatial vision.

This project aims to combine optical and behavioural methods to explore how colour information is channelled from individual cone photoreceptors through the living human retina, to the brain. By non-invasively stimulating either a single cell or specific arrangements of cells, the project aims to contribute fundamental knowledge about how the retina is wired to inform our exquisite sense of colour and spatial vision. This understanding has consequences across a range of disciplines, including artificial vision systems such as driverless cars, retinal disease, and the processing of information through neuronal connections in general.Read moreRead less
Neuronal origin of functional maps on the mammalian visual cortex. This project aims to study how the brain processes images. Basic features of objects in the visual scene seem to be coded on the visual cortex in an orderly way. By recording neurones’ electrical activity in a mammalian brain, this project aims to study how such organisation is determined at the neuronal level, namely how the individual nerves and synapses that form the brain and process the signals are organised to form the over ....Neuronal origin of functional maps on the mammalian visual cortex. This project aims to study how the brain processes images. Basic features of objects in the visual scene seem to be coded on the visual cortex in an orderly way. By recording neurones’ electrical activity in a mammalian brain, this project aims to study how such organisation is determined at the neuronal level, namely how the individual nerves and synapses that form the brain and process the signals are organised to form the overall functional architecture visible at a macroscopic level. This understanding could realise the basis of normal visual perception in robotic vision and brain-machine interfaces.Read moreRead less
Using lasers to prime the immune system. This project aims to detail the precise effects that lasers have on eye cells, cell populations and the body as a whole. Laser treatments for sight problems are increasing but the effects of these laser applications on the unique immune systems of the eye and brain are unknown. Previous work of the researchers has shown that a novel nanosecond laser when targeted to the eye can alter cells in the lasered eye and in the unlasered eye and the brain.

Laser treatments for sight problems are increasing but the effects of these laser applications on the unique immune systems of the eye and brain are unknown. Previous work of the researchers has shown that a novel nanosecond laser when targeted to the eye can alter cells in the lasered eye and in the unlasered eye and the brain. This knowledge may be crucial for enhancing our understanding of the immune privileged state of the eye. In addition, it seeks to guide the development of future low energy lasers as important successful treatments.Read moreRead less
The Calcium Channel TRPV4 In Skeletal Development And Arthritis

Summary
We have discovered that mutations in a calcium channel gene, TRPV4, cause an inherited osteoarthritis in the hands and feet. This work suggests that TRPV4 may be important in osteoarthritis and suggests the exciting possibility that modulating TRPV4 activity may provide a new therapeutic approach for arthritis. We will study how and why the mutations disrupt channel function and study mouse models to see if they are more or less susceptible to arthritis.
How the brain generates robust behaviour in noisy sensory environments. This project aims to investigate the origins of variability in the control of movements. This project expects to generate new knowledge in the area of sensory and motor neuroscience by determining how variability in the activity of sensory and motor neurons accounts for variability in the initiation and control of eye movements. Expected outcomes of this project include international collaboration, development of new methods ....How the brain generates robust behaviour in noisy sensory environments. This project aims to investigate the origins of variability in the control of movements. This project expects to generate new knowledge in the area of sensory and motor neuroscience by determining how variability in the activity of sensory and motor neurons accounts for variability in the initiation and control of eye movements. Expected outcomes of this project include international collaboration, development of new methods for imaging neural activity in vivo, and refinement of theories concerning the cause and implications of noise in the brain. This should provide significant benefits such as a better understanding of why our movements are variable, and whether it is desirable or possible to minimise this variability. Read moreRead less

Summary
The team is comprised of neurologists, molecular geneticists, physiologists and brain imaging specialists and leads the world in the discovery of the genetic causes of epilepsy. They will continue to identify genes underlying epilepsy and study how genetic variations result in development of seizures. Advanced brain imaging will be used to understand the effects of genetic variation on brain structure and function. This study may lead to new diagnostic methods and treatments for epilepsy.

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
