Plasticity of gastrointestinal vagal afferents. The aim of this project is to identify how leptin modulates specific subtypes of vagal afferent within the gut and the plasticity of this system under different dietary conditions. This proposed project will substantially increase understanding of the interactions between leptin, known to influence food intake, and vagal afferent satiety signals. It will also increase understanding of how these interactions alter in obesity and ultimately provide t ....Plasticity of gastrointestinal vagal afferents.

How does timing affect mammalian brain development and evolution? This project aims to generate fundamental knowledge on the origin of diversity in mammalian brain circuits by studying development of marsupials and rodents. The expected outcome is to elucidate how differences in the timing, rate and sequence of development of gene expression, cell differentiation and circuit formation can relate to the origin of key evolutionary innovations in the mammalian brain. The significance of understandi ....How does timing affect mammalian brain development and evolution? This project aims to generate fundamental knowledge on the origin of diversity in mammalian brain circuits by studying development of marsupials and rodents. The expected outcome is to elucidate how differences in the timing, rate and sequence of development of gene expression, cell differentiation and circuit formation can relate to the origin of key evolutionary innovations in the mammalian brain. The significance of understanding the dynamics of developmental systems that shape complex brain traits includes establishing new developmental paradigms in evolutionary theory, generating new tools to investigate and manipulate brain gene expression in vivo, and the potential discovery of the causes of neurodevelopmental dysfunction.Read moreRead less
Ultradian rhythms in basal metabolism; relationship to thermoregulation, cardiovascular function and behavioural arousal. Results from this project will be of basic theoretical biological importance, and may well provide a foundation for understanding basal metabolic regulation and its link with cardiovascular function.

Results from this project will be of basic theoretical biological importance, and may well provide a foundation for understanding basal metabolic regulation and its link with cardiovascular function. Our findings may provide a new foundation for discovering strategies that alter basal metabolic rate in a manner that improves health and reduces the incidence of obesity related disease such as heart attack and stroke. Thus this research proposal is of special relevance to National Research Priority 2: Promoting and Maintaining Good Health. Obesity and obesity-related medical conditions particularly affect older people, so that our research is also highly relevant to National Research Priority 2 sub-areas: Ageing well, Ageing productively.Read moreRead less

This project aims to investigate the neural bases of behaviour in the mammalian gut. The Enteric Nervous System (ENS) plays a critical role in the propulsion of intestinal contents. This project expects to establish how specific functional classes of enteric neurons control propulsion along the gut. By recording the simultaneous neural activity from hundreds of different functional classes of enteric nerve cells simultaneously, whilst recording intestinal muscle electrical activity and the movements of the gut wall, the project expects to identify which enteric neurochemical classes of neurons generate specific motor patterns along the intestine.Read moreRead less

It is proposed to establish a South Australian Facility for rapid rate transcranial magnetic stimulation (TMS) which will be the only one in Australia. This Facility will provide enormous opportunities for collaborative cutting edge investigations into the role of the human cortical areas in a diverse range of tasks. For example, projects have been identified projects employing rTMS to study sensorimotor cortical plasticity, facilitate functional recovery following stroke and investigate the mechanisms of savant behaviour. Provision of this Facility will provide further support for this productive and internationally renowned group of scientists to develop their research programs.Read moreRead less

This project aims to improve human brain models in vitro by developing an analytical tool benchmarking biophysical similarities to the adult human cortex. This project expects to generate new knowledge by testing for the first time the theory that integrating sensory-like inputs and awake/sleep-like cycles of electrical activity in vitro may complete the maturation of human brain organoid models. It will also generate new methods to simplify the analysis of multimodal path-clamping data (Patch-seq). Expected outcomes will facilitate research collaboration and the reproducibility of accurate experimental replicates of the human brain. This will provide significant benefits in the global race to understand human brain computation mechanisms.Read moreRead less

This project aims to address fundamental questions in neuroscience and to integrate this biological understanding with the development of leading-edge robotics. Whether a human catching a ball or a dragonfly feeding in a swarm, brains have the remarkable ability to predict the future location of moving targets. The brain predicts in the presence of distractions and even if the target disappears, for example, when hidden behind another object. This project will investigate how brains use both environmental and internal information to select a target and predict its future location. By implementing bio-inspired computations in hardware, this project aims to provide significant benefits such as improving autonomous systems for defence, health and transportation.Read moreRead less
