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
