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.

The knowledge produced will also make possible world-class innovations in robotics, leading to novel automated vision systems with applications in industry and national security. Other knowledge will develop novel diagnostic technologies, for application in health delivery.Read moreRead less
Probing norepinephrine transporter (NET) structure-function. More selective drugs are needed to improve the treatment of a range of diseases including pain, depression and anxiety. This project will apply advanced molecular pharmacology approaches to better understand how the norepinephrine transporter functions and where small molecules and conotoxins bind to inhibit its activity.
Neural mechanisms of attention in the honeybee and Drosophila melanogaster. By examining convergent neural mechanisms of attention in insects and comparing these mechanisms to those found in vertebrates, we may uncover basic principles of how attention operates in widely divergent systems. This type of basic scientific research could be used to provide a framework to develop better approaches for treatment for individuals with defects in attention. Such defects are symptoms of several psycholo ....Neural mechanisms of attention in the honeybee and Drosophila melanogaster. By examining convergent neural mechanisms of attention in insects and comparing these mechanisms to those found in vertebrates, we may uncover basic principles of how attention operates in widely divergent systems. This type of basic scientific research could be used to provide a framework to develop better approaches for treatment for individuals with defects in attention. Such defects are symptoms of several psychological conditions, including attention deficit disorder, autism, and schizophrenia, which have major social and economic costs in Australia. Therefore, by expanding our understanding of how attention operates at the level of neurons, we can begin to develop targeted treatments for addressing these conditions. Read moreRead less
Using toxins to understand the mechanisms of pain. Toxins have evolved in plants, animals and microbes as part of defensive and/or prey capture strategies, and have proven to be invaluable research tools as well as providing leads for potential new therapies. This project will use subtype-selective toxins to define the role of ion channels in pain, using novel pathway-specific and disease-specific animal models of pain. The findings from this project will provide significant insight into the ne ....Using toxins to understand the mechanisms of pain.

This project will use subtype-selective toxins to define the role of ion channels in pain, using novel pathway-specific and disease-specific animal models of pain. The findings from this project will provide significant insight into the neuropharmacology of pain, will lead to the identification of novel molecular targets with analgesic potential and is expected to provide novel treatment approaches for pain.Read moreRead less
Visual guidance of flight in birds. Birds flying rapidly amidst the branches of trees engage continually in a three-dimensional slalom. This project will study birds flying through tunnels and gaps, to understand how they use their eyes and wings to achieve this agility. The results could suggest better designs for unmanned aerial vehicles operating in dense urban environments.
Biologically-inspired detection, pursuit and interception of moving objects by unmanned aircraft systems. Although it is well known that aggressive honeybees are very effective at detecting, pursuing and intercepting moving targets, this behaviour has never been studied quantitatively. This project will use high-speed video cinematography to investigate this behaviour, to develop visual algorithms for the detection of moving targets, and to create dynamical models of the mechanisms that control ....Biologically-inspired detection, pursuit and interception of moving objects by unmanned aircraft systems. Although it is well known that aggressive honeybees are very effective at detecting, pursuing and intercepting moving targets, this behaviour has never been studied quantitatively. This project will use high-speed video cinematography to investigate this behaviour, to develop visual algorithms for the detection of moving targets, and to create dynamical models of the mechanisms that control pursuit. The resulting algorithms will be incorporated into unmanned aerial vehicles for detecting, monitoring and tracking other objects in the sky, and their performance will be evaluated. The results will provide a better understanding of the biological basis of pursuit behaviour, as well as lead to novel technologies for aerial surveillance and safety.Read moreRead less
Strategies for mid-air collision avoidance in aircraft: lessons from bird flight. Birds seldom collide with each other and other objects, despite the high speeds at which they fly in complex environments. This project will examine how birds sense and avoid impending collisions, and will use these results to design novel strategies for the detection and avoidance of aircraft mid-air collisions.
‘Super-human’ colour vision: how does it improve animal visual performance? Colour vision enables animals to find food, attract mates and avoid predators. Many animals, including fish, birds and insects, have ‘super-human’ colour vision systems and process colour using 4 or 5 spectral channels, instead of our 3. Yet we do not know how information is combined across these different channels to achieve colour vision. This project will develop new technology to measure UV vision in a range of anima ....‘Super-human’ colour vision: how does it improve animal visual performance? Colour vision enables animals to find food, attract mates and avoid predators. Many animals, including fish, birds and insects, have ‘super-human’ colour vision systems and process colour using 4 or 5 spectral channels, instead of our 3. Yet we do not know how information is combined across these different channels to achieve colour vision. This project will develop new technology to measure UV vision in a range of animal taxa, and show how animals with 4 or 5 spectral channels integrate or partition visual information to perceive colour. The Fellowship will provide new biological models for the development of next-generation multispectral cameras used in medical, military, security and remote sensing applications.Read moreRead less
Dendritic information processing during sensory-motor behaviour. The neocortex is centrally involved in the control of animal behaviour. It is largely unknown how neocortical neurons contribute to the neuronal computations that generate behaviour. The project will study how individual neurons in the neocortex compute the sensory and motor signals that underlie an important exploratory behaviour in rodents.

Summary
Phenotypic plasticity of reef fish vision in a changing world. This project aims to investigate why fishes have more colour vision channels than any other vertebrate on the planet by studying representatives from the most vibrant ecosystem on earth, the Great Barrier Reef. It is currently not clear how vision is controlled on the molecular level and how this translates to the performance and survival of an animal. Through an innovative approach to understanding colour vision and animal behaviour ....Phenotypic plasticity of reef fish vision in a changing world. This project aims to investigate why fishes have more colour vision channels than any other vertebrate on the planet by studying representatives from the most vibrant ecosystem on earth, the Great Barrier Reef. It is currently not clear how vision is controlled on the molecular level and how this translates to the performance and survival of an animal. Through an innovative approach to understanding colour vision and animal behaviour, this project expects to advance Australia’s leadership in neuroscience and ecology, while also increasing the capacity for international collaborations. Beyond the scientific benefit, it will create public awareness about an endangered ecosystem, inform reef guardianship and may inspire new sensory technology.Read moreRead less
