This study investigates how much an individual's genes and environment account for the wide variation in brain structure and function. Using brain imaging we examine in what way the connectivity of the brain of identical and non-identical twins is the same or different from that of their co-twin, and carry out analysis of their DNA to identify some of the genes involved. This will provide fundamental information on genetic mechanisms influencing variation in brain structure and function.

Summary
Traumatic brain injury in children is common with more than 2000 new cases a year in Queensland and Victoria alone. Many children who experience a brain injury go on to have long-term difficulties such as significant educational and social problems. Post-traumatic stress occurs in children following traumatic physical injury. However it is not clear to what extent this is so for children who have received a traumatic brain injury. Furthermore, when there is a traumatic brain injury and traumatic ....Traumatic brain injury in children is common with more than 2000 new cases a year in Queensland and Victoria alone. Many children who experience a brain injury go on to have long-term difficulties such as significant educational and social problems. Post-traumatic stress occurs in children following traumatic physical injury. However it is not clear to what extent this is so for children who have received a traumatic brain injury. Furthermore, when there is a traumatic brain injury and traumatic stress, it is not clear how these interact, how they influence long-term outcomes, and what factors such as pre-injury functioning and family support and distress mediate outcomes. These issues are very important since effective rehabilitation of children following traumatic brain injury is essential to maximise long-term functioning and minimise disability. To be effective, rehabilitation must be guided by the knowledge about key factors that determine the recovery process. This study aims to provide answers to these questions by following two cohorts of children (aged 6-14) over 18 months after receiving a traumatic brain injury. In total 240 children will be recruited from Brisbane and Melbourne hospitals. They will be assessed at three, six, twelve and eighteen months post-injury using measures of cognitive, psychological and social functioning. Information on parent distress and behaviours will also be obtained. The information obtained will provide the basis for the development of a specific rehabilitation strategy for children with traumatic brain injury, including information on strategies to help prevent any confounding impact of post-traumatic stress on recovery.Read moreRead less
Goal pursuit decisions under environmental and social uncertainty. This project aims to develop an integrative computational model that explains how people prioritise the allocation of resources to different goals in the face of uncertainty. The project seeks to test a new theory through a series of experiments in which participants pursue goals by themselves in unpredictable environments, or in competition against an opponent. Expected outcomes include an integrated theory that accounts for the ....Goal pursuit decisions under environmental and social uncertainty. This project aims to develop an integrative computational model that explains how people prioritise the allocation of resources to different goals in the face of uncertainty. The project seeks to test a new theory through a series of experiments in which participants pursue goals by themselves in unpredictable environments, or in competition against an opponent. Expected outcomes include an integrated theory that accounts for the effects of both environmental and social uncertainty in the pursuit of multiple goals. Intended benefits include the development of computational models that can simulate human decision making in complex environments, analyse new concepts of operation, redesign work roles, and identify factors that reduce risk in decision-making.Read moreRead less
Signaling Pathways To Enhance Potency Of AMPK-targeting Drugs

Funding Amount
$661,966.00
Summary
Sedentary lifestyles and consumption of high energy foods has led to epidemics of obesity-related metabolic diseases that place enormous financial and medical burden on the Australian economy. An attractive drug target to treat these diseases is AMP-activated protein kinase (AMPK) which functions as both a cellular fuel gauge and co-ordinator of whole-body metabolism. Our goal is to improve AMPK drug potency by identifying novel processes that sensitize AMPK to drugs.
The Healthy Brain Project: A Prospective Cohort Study To Examine How Later-life University Education May Affect The Trajectory Of Ageing-related Cognitive Decline

Funding Amount
$1,085,742.00
Summary
Previous research has indicated that higher levels of education in early adulthood are associated with lower risk for dementia in older adults. This world-first project will examine if older adults who undertake university education have reduced rates of age-related cognitive decline than older adults who do not undertake further education. This would support the notion that boosting cognitive reserve in later life is protective against age- and disease-related neurodegenerative change.
Self-deception as a tool for deceiving others. This research will test the theory that people deceive themselves to deceive others. Support for this theory would enhance our understanding of how we deceive others and why we sometimes deceive ourselves.
Modelling human decision making in complex environments. The project aims to extend quantitative psychological models of simple choice tasks to decision-making with complex stimuli in complex environments. The new formal models are designed to provide a comprehensive account of behaviour, including the choices that are made, how long it takes to make them, and how choices and choice times vary within and between decision-makers. The models would explain how people adapt to changes in task demand ....Modelling human decision making in complex environments. The project aims to extend quantitative psychological models of simple choice tasks to decision-making with complex stimuli in complex environments. The new formal models are designed to provide a comprehensive account of behaviour, including the choices that are made, how long it takes to make them, and how choices and choice times vary within and between decision-makers. The models would explain how people adapt to changes in task demands when dealing with multiple stimuli or performing multiple tasks concurrently under time pressure. The project aims to provide the basic research that is needed to extend psychological models of choice to complex ‘real-world’ tasks, such air traffic control and maritime surveillance.Read moreRead less
An innovative theory driven approach to enhancing situation awareness among road users in Australia. This project will develop, via on-road studies exploring road user behaviour, a first of its kind systems theoretic model of situation awareness (SA) for road transport. The model will then be used to inform the development of roadway design solutions to enhance road user SA, which will be tested through advanced simulation.
A new complex systems approach to road trauma: Applying systems thinking to the fatal five. By 2030 road trauma is expected to be the fifth leading cause of global deaths. The current road user centric road safety approach has failed to control the global health epidemic of road trauma. Although systems thinking is widely accepted to be the most effective approach for understanding and enhancing safety in complex systems, it has not yet been adopted in road safety efforts.

The current road user centric road safety approach has failed to control the global health epidemic of road trauma. Although systems thinking is widely accepted to be the most effective approach for understanding and enhancing safety in complex systems, it has not yet been adopted in road safety efforts. This project aims to apply a novel, integrated framework of systems analysis and design methods to the so called 'fatal five' causes of road trauma to create new knowledge on their causes and to develop and test new interventions that will enable the achievement of currently unreachable road safety targets.Read moreRead less
