Functional imaging of colour pathways in the living eye. In order to repair or regenerate a diseased eye, we require knowledge of the normal pattern or nerve cell connections, and knowing how biology solves the problem of colour vision can be used to improve the design of artificial vision systems. The adaptive optics machine we will build in this project can be used to image nerve cells, fine blood vessels, and nerve fibre bundles in the normal and diseased eye. This will improve Australia's re ....Functional imaging of colour pathways in the living eye.

The adaptive optics machine we will build in this project can be used to image nerve cells, fine blood vessels, and nerve fibre bundles in the normal and diseased eye. This will improve Australia's research and development capacity in this new area of medical diagnostics. Our machine will be made available to other Australian laboratories and will improve the national capacity for making further scientific discoveries about how the visual system works.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
Developing innovative contact lens designs and materials for effective and safe corneal refractive reshaping. Despite the increasing prevalence of refractive errors, there are limited options available for refractive error correction. Current contact lens designs for orthokeratology, a corneal reshaping technique which temporarily reduces refractive error, are effective for correcting only low to moderate myopia (short-sightedness). In this project, we will use innovative lens design approache ....Developing innovative contact lens designs and materials for effective and safe corneal refractive reshaping. Despite the increasing prevalence of refractive errors, there are limited options available for refractive error correction. Current contact lens designs for orthokeratology, a corneal reshaping technique which temporarily reduces refractive error, are effective for correcting only low to moderate myopia (short-sightedness). In this project, we will use innovative lens design approaches that harness the fluid forces generated in the post-lens tear film, and modulation of the corneal tissue response to these pressures, to develop novel contact lens designs in appropriate lens materials for effective and safe corneal reshaping to correct a wide range of refractive errors.Read moreRead less
The future of corneal refractive reshaping: can we control myopia or is the risk of corneal compromise too great? Refinement of corneal reshaping lens designs, optimised for visual outcomes through manipulation of aberrations, will significantly benefit local contact lens manufacturing and export by expanding the existing market base. This research will also strategically position Australian lens manufacturing to capitalise on the market for myopia-control contact lenses, particularly in the As ....The future of corneal refractive reshaping: can we control myopia or is the risk of corneal compromise too great? Refinement of corneal reshaping lens designs, optimised for visual outcomes through manipulation of aberrations, will significantly benefit local contact lens manufacturing and export by expanding the existing market base. This research will also strategically position Australian lens manufacturing to capitalise on the market for myopia-control contact lenses, particularly in the Asian region. Significant intellectual property will be generated for Australia in terms of enhanced understanding of the role of manipulation of corneal shape in modulating progressive myopia. Outcomes from this project will enhance the international reputation of the UNSW research group, keeping Australian science at the forefront of this area of research.Read moreRead less

Small animal molecular imaging is a powerful tool in biological research and drug discovery. Anaesthesia is routinely used to avoid motion distortion, but can profoundly alter the biological process studied. This research will enable quantitative imaging of neurobiological phenomena in awake laboratory animals. It will create new opportunities for Australian basic researchers to use innovative technology with expected high economic potential, and benefit small biotech companies by facilitating pre-clinical and clinical development of new pharmaceuticals. The new motion tracking and image reconstruction technologies developed will strengthen Australia's leading position in engineering and biomedical systems development.Read moreRead less
Evolution of sound localisation in vertebrates: head size, sound frequency and neural phase-locking. Hearing is our most important sense for interpersonal communication, yet we have a fragmentary understanding of the basic mechanisms involved in normal hearing. This project addresses the question of how sound location is represented in the brain through the processing of minute time difference with which sounds reach the two ears. The outcome will ultimately enable us to infer how the human brai ....Evolution of sound localisation in vertebrates: head size, sound frequency and neural phase-locking.

Optical imaging of brain activity: Studies of the neural basis of sensory perception, plasticity and behaviour. Basic to the understanding of the brain is to know how the overall architecture of the nervous system relates to its function. We propose to study this by directly visualising the regions that are functionally active in the living brains of animals, down to resolution limits of less than 100 micrometres. Such "optical imaging" will be done by recording light reflected from the surfac ....Optical imaging of brain activity: Studies of the neural basis of sensory perception, plasticity and behaviour. Basic to the understanding of the brain is to know how the overall architecture of the nervous system relates to its function. We propose to study this by directly visualising the regions that are functionally active in the living brains of animals, down to resolution limits of less than 100 micrometres. Such "optical imaging" will be done by recording light reflected from the surface of the brain, which in turn depends upon activity-dependent intrinsic signals (eg. degree of oxygenation of haemoglobin). These signals will be recorded by a special camera and amplified using the requested system.Read moreRead less
