Novel mechanisms integrating the central and autonomic nervous system. This project aims to define molecular mechanisms controlling the exquisite connectivity of neurons in different parts of the body. The ability of higher-vertebrates to respond to different environmental conditions is essential for life, evolution, health, reproduction and growth, and is reliant on the autonomic nervous system. However, how the autonomic nervous system is integrated with the central nervous system to control h ....Novel mechanisms integrating the central and autonomic nervous system. This project aims to define molecular mechanisms controlling the exquisite connectivity of neurons in different parts of the body. The ability of higher-vertebrates to respond to different environmental conditions is essential for life, evolution, health, reproduction and growth, and is reliant on the autonomic nervous system. However, how the autonomic nervous system is integrated with the central nervous system to control holistic physiological responses is largely unknown. By deciphering how neural networks are formed this project aims to provide broad biological insight to wiring of the entire nervous system which is likely to have significant implications for the formation of synthetic neural networks and for regeneration.Read moreRead less

Summary
Early developmental influences on neocortical organisation. This project seeks to identify the influence of preceding developmental stages on the correct formation of the brain. Development is a sequence of transformations where every stage depends on the outcome of previous stages. The project intends to examine how the early sensory periphery, early-born brain circuits, and intrinsic neuronal interactions affect the subsequent organisation of the cerebral cortex – a mammal-specific brain regio ....Early developmental influences on neocortical organisation. This project seeks to identify the influence of preceding developmental stages on the correct formation of the brain. Development is a sequence of transformations where every stage depends on the outcome of previous stages. The project intends to examine how the early sensory periphery, early-born brain circuits, and intrinsic neuronal interactions affect the subsequent organisation of the cerebral cortex – a mammal-specific brain region responsible for perception, motor planning and cognition. It expects to provide novel mechanistic and conceptual insights into the process of normal brain development and more general biological phenomena, such as development and evolution. It may also provide insights into several genetic and non-genetic causes of brain malformations.Read moreRead less
The developmental genetics of major evolutionary transitions: a multidisciplinary investigation of limb reduction and loss in lizards. The five-toed limb is an iconic evolutionary innovation of land vertebrates, yet has been lost repeatedly. This project will use anatomical, developmental and genetic approaches to understand how vertebrates lose their legs, whether limbs can be reacquired, and the degeneration of limb genes after they lose their function (analogous to 'vestigial organs').

This multi-institutional proposal aims to establish a state-of-the-art Lightsheet microscope facility in South Australia with enhanced analysis infrastructure and a national user support network. Expectations are, this will transform researcher outcomes for multiple disciplines by facilitating high-resolution four-dimensional interrogation of novel biological processes. Significant benefits will include the ability to image deep within living tissue over long time-scales without inducing phytotoxicity to produce high-impact fundamental and translatable outcomes, the development of novel probes and methodologies, new cross-disciplinary collaborations, and new and unique funding, student training and public engagement opportunities.Read moreRead less
The immune response as a determinant of female reproductive investment. Aims: This project will define how ‘cryptic female choice’ affects reproductive outcomes through immune recognition of embryo histocompatibility genes, to modulate maternal nutrient provision and fetal growth.
Significance: The research will tackle an important knowledge gap in animal reproduction science, where poorly-understood male-female compatibility effects cause variation in breeding efficiency with major economic an ....The immune response as a determinant of female reproductive investment. Aims: This project will define how ‘cryptic female choice’ affects reproductive outcomes through immune recognition of embryo histocompatibility genes, to modulate maternal nutrient provision and fetal growth.
Significance: The research will tackle an important knowledge gap in animal reproduction science, where poorly-understood male-female compatibility effects cause variation in breeding efficiency with major economic and environmental impact.
Expected outcomes: We expect to generate new understanding of the genes, immune response elements, and vascular changes that explain compatibility effects.
Benefits: The results will inform strategies to improve fertility in livestock animals, and in rare and threatened species.

Going with the flow: directing nutrient rich blood to the brain. This project aims to visualise and measure flow of blood from the umbilical cord to the fetal brain and to understand how delivery of oxygen and glucose to the brain is prioritised by constriction or relaxation of a specialised shunt, the ductus venosus. The project will directly and non-invasively measure this fundamental phenomenon with novel MRI protocols. Expected outcomes of this project include advances in measuring fetal blo ....Going with the flow: directing nutrient rich blood to the brain. This project aims to visualise and measure flow of blood from the umbilical cord to the fetal brain and to understand how delivery of oxygen and glucose to the brain is prioritised by constriction or relaxation of a specialised shunt, the ductus venosus. The project will directly and non-invasively measure this fundamental phenomenon with novel MRI protocols. Expected outcomes of this project include advances in measuring fetal blood flow and the exchange of expertise between leading researchers in Australia and Canada. In the long-term, this will enhance Australia’s research capacity in fetal physiology and may lead to new tools for monitoring or supporting fetal development.Read moreRead less
Normal heart development before birth. This project aims to understand how the fetal heart can develop normally with much less oxygen than an adult heart uses. Regulation of fetal heart proliferation is not well understood but changes in oxygen levels and non-coding RNAs are implicated. Using advanced imaging techniques to measure blood flow in blood vessels to the fetal heart and molecular probes to assess cell function and microarrays to measure non-coding RNA, the project expects to generate ....Normal heart development before birth.

Regulation of fetal heart proliferation is not well understood but changes in oxygen levels and non-coding RNAs are implicated. Using advanced imaging techniques to measure blood flow in blood vessels to the fetal heart and molecular probes to assess cell function and microarrays to measure non-coding RNA, the project expects to generate new knowledge about mechanisms of fetal heart cell proliferation. Ultimately, this new knowledge could lead to non-invasive approaches to detect and treat abnormal fetal heart growth in animals and humans.Read moreRead less
