Integrating holistic processing and face-space approaches to the perception of facial identity. Recognising faces is a socially crucial task, and humans are remarkably good at it. Scientists investigating the 'software' our brains use to recognise faces have referred to two different theories -- one when explaining why we distinguish faces better than objects, and the other in explaining why we distinguish some people's faces more easily than others. The project aims to integrate these two theor ....Integrating holistic processing and face-space approaches to the perception of facial identity. Recognising faces is a socially crucial task, and humans are remarkably good at it. Scientists investigating the 'software' our brains use to recognise faces have referred to two different theories -- one when explaining why we distinguish faces better than objects, and the other in explaining why we distinguish some people's faces more easily than others. The project aims to integrate these two theories. This has two potential long-term benefits: it will give a stronger basis for understanding what goes wrong in people where face recognition does not develop normally; and, the improved knowledge from a biological system may also lead to improved computer face recognition algorithms (eg. for airport security).Read moreRead less
Testing theoretical models of age and disease related changes to inform prevention. Pathological brain changes associated with future cognitive decline become detectable in the 40s or earlier. Yet little is known about what constitutes normal brain ageing in mid-life. Using a number of neuroimaging and epidemiological techniques this project will scrutinise brain and cognitive ageing in middle-age and their significance.
Future Keepers: impacts of climate change on ecosystem function providers. The aim of this project is to predict how key ecosystem service providers may change under resource limitation and thermal stress. The project seeks to assess how common species respond to climatic fluctuations and resource limitations when competing for resources in familiar and novel environments along six biogeographic transects throughout Australia. In combination with hypothesis-driven field, laboratory and transplan ....Future Keepers: impacts of climate change on ecosystem function providers. The aim of this project is to predict how key ecosystem service providers may change under resource limitation and thermal stress. The project seeks to assess how common species respond to climatic fluctuations and resource limitations when competing for resources in familiar and novel environments along six biogeographic transects throughout Australia. In combination with hypothesis-driven field, laboratory and transplant experiments, citizen science will be used to create a longitudinal data set of the constraints put on dominant and functionally important species. The project also seeks to enable more robust forecasting of biological responses to environmental change by integrating both empirical and theoretical capabilities.Read moreRead less
Variation in the arginine vasopressin 1a receptor (AVPR1a) gene, the social environment, general health and wellbeing. The project aims to investigate how the arginine vasopressin 1a gene affects gene expression and influences social behaviour and ultimately health and wellbeing. This research will contribute to understanding the importance of individual differences in social policy and interventions aimed at improving health and wellbeing.
Temperature-dependent toxicity of plant secondary compounds to mammalian herbivores. Changes in the toxicity of plant secondary compounds is an unexplored consequence of rises in ambient temperatures. Evidence from agricultural and laboratory studies suggests that temperature dependent toxicity can have major effects on the intake and metabolism of plant secondary metabolites by mammals. These effects are mediated by a decrease in liver metabolism and by the effects of plant secondary metabolite ....Temperature-dependent toxicity of plant secondary compounds to mammalian herbivores. Changes in the toxicity of plant secondary compounds is an unexplored consequence of rises in ambient temperatures. Evidence from agricultural and laboratory studies suggests that temperature dependent toxicity can have major effects on the intake and metabolism of plant secondary metabolites by mammals. These effects are mediated by a decrease in liver metabolism and by the effects of plant secondary metabolites on mitochondrial function which leads to greater heat production. The project will quantify the importance of temperature dependent toxicity and measures the changes in the cost of detoxification to better model the effects of climate change on marsupial herbivores.Read moreRead less
Sensory integration in the whisker pathway: cortical transformations and the neuronal mechanisms that underlie decision confidence. How does the brain use information collected by sensory systems to make decisions? This study combines behavioural experiments with neuronal recording from various brain regions to understand the neuronal mechanisms that integrate sensory signals to generate representations and guide the appropriate behavioural action.
Perceptual and psychosocial factors associated with individual differences in face identity and face expression processing. What makes one person better or worse than another at recognising faces, or the emotions displayed in those faces? This project examines which aspects of visual perception contribute to these abilities, and their associations with problems such as debilitating social anxiety and young children's anti-social behaviour.

Summary
A MEG-based cognitive neuroscience laboratory. At present there is no MEG system in Australia, whereas MEG systems are currently springing up in research institutions in many other countries across the globe. This project will enable Australia to remain at the forefront of research in the cognitive neurosciences, as well as provide training opportunities to Australian doctoral students and postdoctoral fellows in the use of MEG in research. Finally, the MEG laboratory will allow Australian resea ....A MEG-based cognitive neuroscience laboratory. At present there is no MEG system in Australia, whereas MEG systems are currently springing up in research institutions in many other countries across the globe. This project will enable Australia to remain at the forefront of research in the cognitive neurosciences, as well as provide training opportunities to Australian doctoral students and postdoctoral fellows in the use of MEG in research. Finally, the MEG laboratory will allow Australian researchers to fill important gaps in our understanding of several areas of cognitive neuroscience, including basic auditory and visual processing, the study of cognitive processing in schizophrenia and in children with dyslexia and/or specific language impairment.Read moreRead less
Sleeping for Gold: The Influence of Sleep on the Sports Performance of Elite Athletes. The aim of this project is to improve the performance of Australia's elite athletes by enhancing the amount and quality of sleep that they obtain. This project will have three major benefits. First, successful role models will encourage more Australian children and adults to participate in sport. This is critical given that the incidence of obesity (a major risk factor for diabetes, cardiovascular disease and ....Sleeping for Gold: The Influence of Sleep on the Sports Performance of Elite Athletes. The aim of this project is to improve the performance of Australia's elite athletes by enhancing the amount and quality of sleep that they obtain. This project will have three major benefits. First, successful role models will encourage more Australian children and adults to participate in sport. This is critical given that the incidence of obesity (a major risk factor for diabetes, cardiovascular disease and some cancers) has doubled in Australia in the last 15 years as participation in sport has dropped. Second, the success of our elite athletes will provide a source of pride in our achievements as a nation. Third, this research will enable the Australian Institute of Sport to remain as an international leader in sports science research.Read moreRead less
Neuronal and behavioural correlates of sensory adaptation. Sensory systems adapt to the statistics of their environment, and the consequences of this adaptation are evident in neuronal activity and in animal’s behaviour. This project will employ a novel paradigm to characterise how adaptation changes the response properties of individual sensory neurons to improve efficiency of information transmission.
