Brain Research And Integrative Neuroscience Network. The brain is the ultimate frontier of science, and its complexity requires an integrative approach to neuroscience. This initiative will facilitate a unique integration of disciplines (biological, physical, computational) and scales of focus (single neurons to networks to whole-brain), within a high profile Network of Australian and international players. The Network will be harnessed by a centralized hub for sharing of data and techniques, and mentoring of early career researchers. The principal socio-economic and discovery outcomes will flow from the exceptionally strong foundations in fundamental and applied science, established collaboration, and demonstrated capacity for development and commercialization of frontier biotechnologies.Read moreRead less
Wiring up the nervous system: how do axons detect molecular gradients? This project will improve our understanding of how the nervous system
becomes wired up during development. This will ultimately allow better
therapies for some types of developmental disorders, and for repairing
damaged connections for instance in the spinal cord. The theoretical
models developed will improve our understanding of the computations
necessary to generate appropriate wiring of the nervous system, which

therapies for some types of developmental disorders, and for repairing
damaged connections for instance in the spinal cord. The theoretical
models developed will improve our understanding of the computations
necessary to generate appropriate wiring of the nervous system, which
may facilitate the development of self-organizing computing
devices. The project will also provide unique research training at the
interface of biology and computation, building capacity for such
interdisciplinary research throughout Australia.

Interactions between phenome and genome at developing CNS synapses during synaptic refinement. Activity-dependent changes in synaptic transmission are vital to development and function of central neuronal networks. However, the critical factors regulating developmental changes in synaptic signals remain largely unknown. We will correlate functional changes in synaptic responses at glutamate-releasing synapses with changes in glutamate receptor composition at a critical period during developmen ....Interactions between phenome and genome at developing CNS synapses during synaptic refinement. Activity-dependent changes in synaptic transmission are vital to development and function of central neuronal networks. However, the critical factors regulating developmental changes in synaptic signals remain largely unknown. We will correlate functional changes in synaptic responses at glutamate-releasing synapses with changes in glutamate receptor composition at a critical period during development, test whether synaptic activation of receptors is required for these changes and define the pattern of activity-dependent changes in gene expression necessary for developmental changes in synaptic transmission. Understanding this interaction between synaptic phenome and activity-dependent genomic expression will expand our understanding of brain development and function.Read moreRead less
HIDE AND SPEAK - COLOUR COMMUNICATION IN REEF FISH. Fish play an important role in many Australian's lives, they are a source of recreation for scuba divers, snorkelers and fishermen, they are a draw card for tourists as well as a healthy source of food. This project will investigate the visual world of fish, unravelling their use of colour communication, thereby identifying environmental factors affecting successful communication. Such a study will provide insight into the impact on reef fish o ....HIDE AND SPEAK - COLOUR COMMUNICATION IN REEF FISH. Fish play an important role in many Australian's lives, they are a source of recreation for scuba divers, snorkelers and fishermen, they are a draw card for tourists as well as a healthy source of food. This project will investigate the visual world of fish, unravelling their use of colour communication, thereby identifying environmental factors affecting successful communication. Such a study will provide insight into the impact on reef fish of changes in water quality (e.g. river runoff) and temperature (e.g. bleaching events), as well as factors that affect the successful rearing of fish in aquaculture.

Summary
Neurobiological mechanisms of decision under uncertainty. The purpose of this project is to understand the behavioural and brain mechanisms underlying decision under uncertainty. This research will uncover the effect that normal variation in brain networks has on choice and contribute to a better understanding of disorders linked to intolerance of uncertainty.
A new theory for retinotectal map formation. How brains become wired up during development is a question of
importance to both biology and computing. In this project we adopt a
novel computational approach to understanding the development of
topographic maps, a wiring pattern that is ubiquitous in biological
nervous systems. This project will build capacity for research in
computational neuroscience in Australia. It may also lead to
technological benefits such as new ideas for the design o ....A new theory for retinotectal map formation. How brains become wired up during development is a question of

novel computational approach to understanding the development of
topographic maps, a wiring pattern that is ubiquitous in biological

computational neuroscience in Australia. It may also lead to
technological benefits such as new ideas for the design of self-wiring
computing devices, and new insights into
the causes of wiring defects both during normal development and
rewiring after injury.

Dopaminergic mechanisms of visual selective attention in the fly. What we pay attention to guides our behaviour. There is increasing evidence that even the smallest animals, such as insects, have a selective attention. Neuromodulators such as dopamine (DA) regulate general arousal states in flies as well as humans, but it is not well understood how DA modulates selective attention. This project will genetically manipulate DA in the fly Drosophila in order to study its role in visual selective at ....Dopaminergic mechanisms of visual selective attention in the fly. What we pay attention to guides our behaviour. There is increasing evidence that even the smallest animals, such as insects, have a selective attention. Neuromodulators such as dopamine (DA) regulate general arousal states in flies as well as humans, but it is not well understood how DA modulates selective attention. This project will genetically manipulate DA in the fly Drosophila in order to study its role in visual selective attention, by: examining neural circuits; attention behaviour; and, brain recordings. Our work will reveal whether DA mainly controls general responsiveness levels, or whether DA is also involved in coordinating attention dynamics. This study has important implications for understanding attention disorders.Read moreRead less
Effect of infant hand observation training on the early development of hand reaching and grasping in healthy infants and those with early brain damage. The best way to learn a new motor skill is to look at people who can already do it. But is this also true for infants? And, can we help infants with motor problems by teaching them how to do it? This project aims to answer these questions by studying training based on the observation of parent's actions by infants with and without brain damage.
Network activity and the role of NMDA receptors in associative learning. The brain is the most complex machine we know, and its activity shapes every aspect our lives. Studies over decades using tools from molecular and cellular neuroscience and behavioural experiments have discovered the parts of the brain involved in learning and memory formation. Much is understood about the neural circuits that mediate learning but how memories are formed and stored are not understood.

Studies over decades using tools from molecular and cellular neuroscience and behavioural experiments have discovered the parts of the brain involved in learning and memory formation. Much is understood about the neural circuits that mediate learning but how memories are formed and stored are not understood. The aim of this project is to understand learning and memory formation using a simple Pavlovian learning paradigm, fear conditioning. Using cutting-edge molecular tools we will label the circuits in the amygdala that mediate this learning and the nature of the memory trace. In the long term, these results may drive novel storage devices.Read moreRead less
