1980年Merton 和Morton 首次成功采用了非损伤性刺激大脑皮质运动区,记录大鱼际肌运动电位的方法。Ludolph 等人的动物(猕猴)试验表明此方法测出的脊髓运动潜伏期与硬膜内神经传导速度的测定结果相符。刺激后脑组织无形态学改变。方法:正极用表面电极(Ag/AgCl),(?)1.5cm,作刺激运动皮质区之用。中央前回相应皮质区:上肢为内耳道投影线额前侧2cm,旁开7cm;下肢为中线旁开4cm。负极由12片小金属片(29×19×1cm)组成,颅顶中线旁开3cm 围绕头部固定。诱导电极用表面电极。主极置于肌腹,付极置于相应肌
1980 Merton and Morton for the first time successfully adopted a non-invasive stimulation of the cerebral cortex motor area, record the great motor muscle movement potential method. The Ludolph et al. Animal (cynomolgus) test showed that the spinal motor latency measured by this method was consistent with the intradural nerve conduction velocity measurement. No morphological changes of brain tissue after stimulation. Methods: The positive electrode (Ag / AgCl), (?) 1.5cm, for the stimulation of motor cortex area purposes. Central back to the corresponding cortical area: the upper extremity of the projection line of the ear canal 2cm, 7cm aside; lower extremity midline open 4cm. Negative electrode consists of 12 small pieces of metal (29 × 19 × 1cm) composition, the midline of the skull off 3cm around the head fixed. Induction electrode surface electrode. The main pole in the muscle belly, very placed in the corresponding muscle
