Rapid motor responses in young and older adults. This proposal aims to contribute to our understanding of basic neural mechanisms mediating rapid motor actions across our lifespan. One in four Australians will be over the age of 65 by the year 2056. The project plans to investigate how changes in brain structure and function, as well as alterations in cognitive processing abilities that occur in older age, affect rapid choices between various alternative motor actions as well as our ability to s ....Rapid motor responses in young and older adults. This proposal aims to contribute to our understanding of basic neural mechanisms mediating rapid motor actions across our lifespan. One in four Australians will be over the age of 65 by the year 2056. The project plans to investigate how changes in brain structure and function, as well as alterations in cognitive processing abilities that occur in older age, affect rapid choices between various alternative motor actions as well as our ability to stop motor responses once they are planned. It plans to combine noninvasive brain stimulation with novel behavioural experiments and computational modelling techniques to develop fundamental new knowledge of the natural processes that characterise age-related changes in rapid motor actions.Read moreRead less
Distribution of ocean heat uptake and its implications for sea level and climate change. Increasing sea levels and ocean temperatures provide critical evidence of long term warming of the climate system. This project will investigate geographical changes in the vertical distribution of heat uptake by the ocean and contribution to sea level changes, including understanding of physical mechanisms and the role of human activity and other natural external and internal factors. The expected outcomes ....Distribution of ocean heat uptake and its implications for sea level and climate change. Increasing sea levels and ocean temperatures provide critical evidence of long term warming of the climate system. This project will investigate geographical changes in the vertical distribution of heat uptake by the ocean and contribution to sea level changes, including understanding of physical mechanisms and the role of human activity and other natural external and internal factors. The expected outcomes will contribute to place more rigorous constraints on the likelihood of future warming and sea level rise projections, and are aligned with scientific deliverables required to address key questions in support of Australia’s climate change policy.Read moreRead less
