Adaptation to a novel dynamical environment accompanies changes of neuronal activities in the primary motor cortex. Here, we investigated the changes resulting from the motor adaptation in human corticospinal excitability thatreflects more macroscopic activity level of the primary motor cortex. We found that the coticospinal excitability exhibited directional tuning property and the preferred direction. The tuning pattern after the adaptation shifted depending on the direction of force field. The corticospinal excitability was systematically modulated depending on the adapted environment and the performed behavior contexts.

对新的动态环境的适应伴随着初级运动皮层神经元活动的变化。在这里，我们研究了人类皮质脊髓兴奋性运动适应引起的变化，这反映了初级运动皮层更宏观的活动水平。我们发现皮质脊髓兴奋性表现出方向性调节特性和优选方向。适应后的调整模式根据力场的方向而变化。根据适应的环境和执行的行为背景，系统地调节皮质脊髓的兴奋性。
