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
Molecular control of postnatal heart development. This project aims to improve our understanding of how the heart develops after birth and the molecules that control this process. Recent advances in tissue engineering have opened up opportunities for the generation of synthetic tissues but these studies have also highlighted a fundamental knowledge gap in our understanding of how complex tissues mature to prepare for life as an adult. Much is known about the molecules that control early embryoni ....Molecular control of postnatal heart development. This project aims to improve our understanding of how the heart develops after birth and the molecules that control this process. Recent advances in tissue engineering have opened up opportunities for the generation of synthetic tissues but these studies have also highlighted a fundamental knowledge gap in our understanding of how complex tissues mature to prepare for life as an adult. Much is known about the molecules that control early embryonic development but little is known about the molecules that control maturation after birth. This project aims to build new knowledge that is expected to improve our ability to generate mature heart muscle cells for stem cell applications, tissue repair and regeneration.Read moreRead less
Battle of the sexes: can surroundings differentially affect male and female mammalian preimplantation embryos. Equality between the sexes is an issue even at conception. The environment surrounding the embryo can bias the development of one sex over another. This project will assist in the understanding of how male and female embryos differ and will improve assisted reproductive technologies for domestic animal breeding programs, endangered animal conservation and human infertility treatment.
Revisiting the ontogeny of vocal learning in birds: from neuron to fitness. This project aims to test the hypothesis that acoustic exposure prior to hatching directly affects gene expression, neural development, behaviour and consequently fitness, in wild populations of songbirds. Recent research suggests that animals are receptive to acoustic parental signals long before birth and may use such previously unrecognised signals to make adaptive developmental decisions. This project will quantify t ....Revisiting the ontogeny of vocal learning in birds: from neuron to fitness. This project aims to test the hypothesis that acoustic exposure prior to hatching directly affects gene expression, neural development, behaviour and consequently fitness, in wild populations of songbirds. Recent research suggests that animals are receptive to acoustic parental signals long before birth and may use such previously unrecognised signals to make adaptive developmental decisions. This project will quantify the effect on neural development and vocal learning in embryonic birds, employing a model songbird species. The outcomes of this study will transform our understanding of the adaptive potential of prenatal vocal learning, which will have significant benefits for human speech and language development.Read moreRead less
Defining signals that regulate intestinal stem cells during organ growth. This project will define the key signals that promote cell division in the stem cells which produce the inner epithelial lining of the gut. This fundamental knowledge is of significance as it will provide information about how key signals are delivered to promote repair of injury to this key cell layer. The gut is a vital organ conserved across species that is prone to injury as it is exposed to a very harsh environment of ....Defining signals that regulate intestinal stem cells during organ growth. This project will define the key signals that promote cell division in the stem cells which produce the inner epithelial lining of the gut. This fundamental knowledge is of significance as it will provide information about how key signals are delivered to promote repair of injury to this key cell layer. The gut is a vital organ conserved across species that is prone to injury as it is exposed to a very harsh environment of bacteria and the products of food digestion. The outcomes of this project will provide an understanding of development and regeneration of the epithelial lining and key signals that may augment repair. The future benefits include improved health outcomes for animals and humans and potential economic benefits.Read moreRead less
