An investigation of limb dynamics as a constraint on human motor learning

每天，我们都会用四肢与各种物体互动。这些物体具有不同的机械特性(动力学)，这需要人类的电机系统提供适当的控制。这个项目试图了解大脑在正常和疾病状态下，如何在我们与新的机械环境相互作用时学习新的肢体动力学。在学习一项新的运动技能的过程中，重复的大脑刺激将被用来选择性地阻断不同皮质区域的贡献，以及后来对该技能的回忆。这将使我们能够明确地确定哪些领域对运动技能的获得至关重要。

Everyday we use our limbs to interact with a variety of objects. These objects have various mechanical characteristics (dynamics), which require the human motor system to provide appropriate control. This project seeks to understand how the brain, in both normal and disease states, learns new limb dynamics as we interact with a novel mechanical environmental. Repetitive brain stimulation will be used to selectively block the contribution of various cortical regions during the learning of a new motor skill and later, the recall of that skill. This will allow us to determine definitively which areas are critical to motor skill acquisition.
