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
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. 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 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
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
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').
