A perimeter defence in Australian processionary caterpillars. Microscopic, detachable hairs on processionary caterpillars cause clinical reactions when they enter the skin or internal tissues of humans and animals. There is a time delay between exposure and the most serious effects, inferring an action more complex than simple irritation. The project aims to test a novel mechanism – how the hairs form a perimeter defence around caterpillars that primes the immune system of potential predators, ....A perimeter defence in Australian processionary caterpillars. Microscopic, detachable hairs on processionary caterpillars cause clinical reactions when they enter the skin or internal tissues of humans and animals. There is a time delay between exposure and the most serious effects, inferring an action more complex than simple irritation. The project aims to test a novel mechanism – how the hairs form a perimeter defence around caterpillars that primes the immune system of potential predators, how these hairs function within the layered caterpillar defensive system and how far setae can disperse. The research will inform relevant authorities and in particular veterinarians of the risks being exposed to processionary caterpillar hairs and add to the theory of predator-prey interaction.Read moreRead less
Assessing gene function in the developing vertebrate brain using zebrafish as a model system. Although the vertebrate brain is the most complicated biological tissue it arises from a very simple sheet of cells during embryogenesis. Groups of nerve cells begin to communicate with each other through long interconnecting processes called axons. This project seeks to understand the role of specific genes in this process. This is the first time that the mechanisms controlling the growth of the ear ....Assessing gene function in the developing vertebrate brain using zebrafish as a model system. Although the vertebrate brain is the most complicated biological tissue it arises from a very simple sheet of cells during embryogenesis. Groups of nerve cells begin to communicate with each other through long interconnecting processes called axons. This project seeks to understand the role of specific genes in this process. This is the first time that the mechanisms controlling the growth of the earliest axons in the vertebrate brain will be examined in a living brain. Our analysis is expected to discover genes that are targets for manipulation of axon growth.Read moreRead less

A Neural Network: Understanding Brain Function. This proposal focuses on the mechanisms that regulate brain function, particularly those underpinning the changes in circuitry (plasticity) caused by altered inputs. As such, its core goal is to create an interface between researchers in the neurosciences, computational modelling, robotics and cognitive sciences in order to facilitate optimum collaborative interactions, identify key research questions and promote training opportunities across a mul ....A Neural Network: Understanding Brain Function. This proposal focuses on the mechanisms that regulate brain function, particularly those underpinning the changes in circuitry (plasticity) caused by altered inputs. As such, its core goal is to create an interface between researchers in the neurosciences, computational modelling, robotics and cognitive sciences in order to facilitate optimum collaborative interactions, identify key research questions and promote training opportunities across a multidisciplinary spectrum. This will drive an integrated and accelerated program of discovery and technological development, enhancing Australia's leadership in this crucial field and helping to highlight new biotechnology opportunities and capture social and economic benefits for the nation.

Perception of pain in simple nervous systems. Research over the past twenty years has revealed that cognitive behaviour in honeybees is much more sophisticated than hitherto assumed. The next frontier is to investigate whether these creatures are capable of experiencing pain. This study will measure the concentrations of biogenic amines and peptides in the haemolymph of injured honeybees, and the preferences of wounded individuals for pain killers to investigate whether bees are capable of exper ....Perception of pain in simple nervous systems. Research over the past twenty years has revealed that cognitive behaviour in honeybees is much more sophisticated than hitherto assumed. The next frontier is to investigate whether these creatures are capable of experiencing pain. This study will measure the concentrations of biogenic amines and peptides in the haemolymph of injured honeybees, and the preferences of wounded individuals for pain killers to investigate whether bees are capable of experiencing a sensation of pain. If the answer is positive, insects may provide new and simple models for the study of pain, and the results could lead to the formulation of guidelines for ethical experimentation with certain classes of invertebrates.Read moreRead less

Rethinking the function of the human foot. Human feet are unique in shape and structure, having evolved to allow upright locomotion. Despite their importance, we don’t understand how foot shape and structure facilitates upright locomotion.This DECRA aims to explore the relationship between foot morphology and foot function. I will close a large knowledge gap by applying novel experimental and shape modelling approaches to provide unprecedented insights into human foot function. The primary expected outcome is a detailed understanding of how foot shape and structure influences our ability to walk and run. This research will create a paradigm shift in how we think about feet in the context of human evolution, human athletic performance and athletic footwear design.Read moreRead less
A role for sleep in optimising attention. All animal brains are prediction machines, which allows even tiny flies to effectively navigate complex environments. To predict what will happen next is important for guiding attention, but also for detecting anything surprising. This project aims to understand how prediction is optimized by sleep in Drosophila flies. We aim to use electrophysiology and calcium imaging to map visual prediction error signals across the fly brain, and then determine how g ....A role for sleep in optimising attention. All animal brains are prediction machines, which allows even tiny flies to effectively navigate complex environments. To predict what will happen next is important for guiding attention, but also for detecting anything surprising. This project aims to understand how prediction is optimized by sleep in Drosophila flies. We aim to use electrophysiology and calcium imaging to map visual prediction error signals across the fly brain, and then determine how genetically controlled delivery of sleep regulates the quality and distribution of these signals. This knowledge will benefit our understanding of how brains balance a capacity for prediction versus surprise, by examining how evolution has solved this difficult problem in the smallest brains.Read moreRead less
Colour vision and photoreceptors in reef fish: a model system to discover the function of double cones. Humans are visual animals and as lucky Australians we love to look at The Great Barrier Reef. This project, while rooted in the complexities of visual neurobiology, uses a recently discovered set of 4 different reef fish from the GBR to teach us more about fundamental principles in vision. These fish, diverse as damselfish and snappers, will help solve a mystery centuries old. Double cones are ....Colour vision and photoreceptors in reef fish: a model system to discover the function of double cones. Humans are visual animals and as lucky Australians we love to look at The Great Barrier Reef. This project, while rooted in the complexities of visual neurobiology, uses a recently discovered set of 4 different reef fish from the GBR to teach us more about fundamental principles in vision. These fish, diverse as damselfish and snappers, will help solve a mystery centuries old. Double cones are the commonest daytime photoreceptor in the eyes of almost all vertebrates (humans without them are exceptions) and yet nobody knows what they do. Reef fish have them, so let's ask them what they see!Read moreRead less
Connectomes arising: linking structure and function in neocortical wiring. The cerebral cortex underpins human cognition, yet exactly how it becomes connected is unknown due to a lack of live developmental assays. We overcome this using prematurely born marsupials, which allow to study cortical development from embryo-like stages with remarkable resolution. This project will study how neural activity arises as the first connections are formed, and link functional and structural networks across d ....Connectomes arising: linking structure and function in neocortical wiring. The cerebral cortex underpins human cognition, yet exactly how it becomes connected is unknown due to a lack of live developmental assays. We overcome this using prematurely born marsupials, which allow to study cortical development from embryo-like stages with remarkable resolution. This project will study how neural activity arises as the first connections are formed, and link functional and structural networks across development in vivo. Experimental manipulations of activity, and computational models will discover developmental rules for precise wiring of cortical connections. Benefits include new methods to study cortical development, and outlining electrical, molecular and neuroanatomical signatures of early mammalian brain formation.Read moreRead less
Molecular mechanisms that regulate the kinetics of neurotransmitter release. Information processing in the human brain plays important roles in normal behaviour and cognition, most of which require rapid and precisely timed neurotransmitter release. However, the molecular mechanisms that control the speed and timing of this release remain largely unclear.

Information processing in the human brain plays important roles in normal behaviour and cognition, most of which require rapid and precisely timed neurotransmitter release. However, the molecular mechanisms that control the speed and timing of this release remain largely unclear. This research project will use a novel mix of electrophysiology, electron microscopy, genetics, biochemistry, and imaging to investigate how the speed of neurotransmitter release is controlled by the most important synaptic protein UNC-13 and its binding partners. This project expects to generate significant knowledge in the area of synaptic transmission. The outcomes will deepen our understanding of neuronal communication and information processing in the brain.Read moreRead less
