Motor control mechanisms for psychological perturbation: Elucidationof spinal reflex network and introduction of non-invasive brain stimulation

本研究通过两个实验考察了心理干扰对运动任务执行过程中脊髓反射的影响。通过愉快和不愉快的情绪促进脊髓反射，以及在心理压力下抑制脊髓反射。此外，我们还通过两个实验研究了经颅直流电刺激引起的运动皮质兴奋性改变对快速运动反应的影响。观察到负极刺激引起的反应和运动时间缩短，提示使用无创性脑刺激促进运动皮质兴奋性可以提高运动技能。

T wo experiments were conducted to investigate the influence of psychological perturbations on spinal reflexes during motor task execution. Facilitation of spinal reflexes by pleasant and unpleasant emotion and inhibition of spinal reflexes under psychological pressure were shown. Furthermore, two experiments were performed to investigate the effect of changes in motor cortex excitability by transcranial direct current stimulation on a quick motor response. Shorten reaction and movement times by anodal stimulation were observed, suggesting that facilitation of motor cortex excitability by using non-invasive brain stimulation could improve motor skills.
