This Project aims to investigate how the ‘decision’ to persist in exerting effort to obtain a reward is encoded in the the brain and affected by stress. This work will generate new knowledge on the neural mechanisms through which stress modifies neural activity to control decision making processes underpinning adaptive behaviours essential for survival. The expected outcomes of this work include enhanced capacity at the interface of behavioural and computational neuroscience, that will in turn provide significant benefits through greater insight into brain functions essential for survival, with long ranging implications for performance optimisation and brain-inspired computing.

Identifying hypothalamic circuits that integrate stress and metabolism. This project aims to investigate how the brain integrates threat during hunger. Using cutting-edge technology to manipulate and record neural activity this project will elucidate the brain circuits that integrate threat and appetite to minimize stress exposure during foraging.

This project aims to investigate how the brain integrates threat during hunger. Using cutting-edge technology to manipulate and record neural activity this project will elucidate the brain circuits that integrate threat and appetite to minimize stress exposure during foraging. This will expand our knowledge on how the brain perceives and responds to hunger and may provide relevant information for a large number of basic biological processes controlling the brain. Expected outcomes of this project will contribute to a better understanding of the circuitry controlling more complex decisions from food selection through to social interactions. This should provide significant benefits for Australia’s competitiveness within neuroscience research.Read moreRead less
Midbrain hunger signalling modifies decision making under conflict. Decision-making is one of the most important and fundamental biological processes executed by the mammalian brain. Environmental threats and physiological pressures, such as hunger, can influence decision-making processes skewing the risk/reward ratio, yet how the brain integrates these conflicting goals to determine action selection is unknown. This project aims to investigate brain chemistry and circuitry controlling decision ....Midbrain hunger signalling modifies decision making under conflict. Decision-making is one of the most important and fundamental biological processes executed by the mammalian brain. Environmental threats and physiological pressures, such as hunger, can influence decision-making processes skewing the risk/reward ratio, yet how the brain integrates these conflicting goals to determine action selection is unknown. This project aims to investigate brain chemistry and circuitry controlling decision making under conflict using a multidisciplinary approach combining behaviour, pharmacogenetics, and sophisticated molecular and functional profiling. The expected outcomes will advance theories regarding the neural organisation and computation of decision making under conflict.Read moreRead less
Neurobiological mechanisms of the interaction between pain and sleep. The project aims to reveal the brain mechanisms behind the interaction between such fundamental biological phenomena as sleep and pain. This highly interdisciplinary project expects to deliver significant insights into how poor sleep changes the brain to increase pain sensitivity in healthy adults, by combining novel lab-based mechanistic sleep and pain manipulations and naturalistic longitudinal observation. The rich multimod ....Neurobiological mechanisms of the interaction between pain and sleep. The project aims to reveal the brain mechanisms behind the interaction between such fundamental biological phenomena as sleep and pain. This highly interdisciplinary project expects to deliver significant insights into how poor sleep changes the brain to increase pain sensitivity in healthy adults, by combining novel lab-based mechanistic sleep and pain manipulations and naturalistic longitudinal observation. The rich multimodal dataset generated by the project will be made publicly available to enhance research transparency and international collaboration. This should provide significant benefits, ultimately opening up ways to improve quality of life and wellbeing of the Australian population.

Paving the way for ultra-long haul flights: strategies to mitigate jetlag. This project aims to develop and test strategies to mitigate jetlag, founded on biophysical modelling of circadian rhythms. It sets out to quantify the speed of circadian adaptation of sleep, alertness, and metabolism after transmeridian travel and to maximise speed of adaptation via optimised timing of light exposure, food, and exercise in-flight and on-the-ground. Expected outcomes include powerful models for jetlag str ....Paving the way for ultra-long haul flights: strategies to mitigate jetlag. This project aims to develop and test strategies to mitigate jetlag, founded on biophysical modelling of circadian rhythms. It sets out to quantify the speed of circadian adaptation of sleep, alertness, and metabolism after transmeridian travel and to maximise speed of adaptation via optimised timing of light exposure, food, and exercise in-flight and on-the-ground. Expected outcomes include powerful models for jetlag strategies, ready for application in air travel. The project will directly inform Qantas’ operations for ultra-long haul flights and their international network more broadly. Project outcomes will benefit society and the economy through improving travellers’ alertness, sleep, and reducing the risk of fatigue-related accidents.Read moreRead less

This project aims to develop a new framework for understanding how the anatomy of the brain shapes its function and influences individual differences in human behaviour. The project expects to develop innovative methods for mapping and modelling human brain function by combining techniques from neuroscience, physics, informatics, psychology, and genetics. Expected outcomes include new tools for analysing brain imaging data, new models of brain structure and function, an understanding of how genes shape brain architecture, and a comprehensive characterization of how individual differences in brain organization relate to behaviour. These outcomes should benefit our understanding of how the brain works and of the biological basis of behaviour.Read moreRead less
Prefrontal dopamine in the dynamic processes of learning across lifetime. To facilitate age-specific adaptive action in a changing environment, how we learn changes not only as we grow, but also as we age. However, the neurobiological processes in these age-related changes are poorly studied. This is a significant knowledge gap that needs to be addressed to promote healthy cognitive development and ageing.

To facilitate age-specific adaptive action in a changing environment, how we learn changes not only as we grow, but also as we age. However, the neurobiological processes in these age-related changes are poorly studied. This is a significant knowledge gap that needs to be addressed to promote healthy cognitive development and ageing. This research program aims to examine the contribution of prefrontal dopamine and its receptors D1 and D2 in associative learning and its inhibition at 9 distinct ages spanning development to ageing in male and female rats. The outcomes will provide a new neuroscientific framework to understand learning and memory throughout life, which will foster new research opportunities and inform our education and health.Read moreRead less
