Rapid motor responses in young and older adults

这一建议旨在帮助我们理解在我们的一生中介导快速运动的基本神经机制。到2056年，四分之一的澳大利亚人将超过65岁。该项目计划调查大脑结构和功能的变化，以及老年认知处理能力的变化，如何影响在各种备选运动动作之间的快速选择，以及我们一旦计划停止运动反应的能力。它计划将非侵入性脑刺激与新颖的行为实验和计算建模技术相结合，以开发表征快速运动动作中与年龄相关的变化的自然过程的基本新知识。

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.
