结果：(1)8例患者均显示额侧占优势的双侧额中央峰波复合物，其中7例在非快速眼动期出现精神张力下降。(2) JLA显示3例MC相关电位。2例SPME患者对侧中央区出现阳性峰，潜伏期在20 msec以下，伴有巨SEP和皮质反射。其余大块性肌阵挛（MM）在双侧额中央优势区出现锐波阳性，比MC早40 msec。结论：(1)撇开所有病例脑电图皮层高兴奋性增强不考虑，8例患者中仅3例记录到MC相关电位。(2) SPME中MC来源于运动皮质。在MM中，提出了与大脑皮层具有时间锁定关系的皮层下起源。(3)非快速眼动期心肌肌张力异常提示脑干单胺能神经元功能障碍。
Results:(1) The polygram disclosed frontal dominant bilateral frontocentral spike and wave complexes in all and the decreased mentalis tonus in non REM stage in 7 of the 8 cases.(2) The JLA revealed MC related potentials in 3 cases. The two with SPME showed positive spikes in the contralateral central area with latency under 20 msec and associated with the giant SEP and the cortical reflex. The remaining case, with massive myoclonus (MM) showed positive sharp wave, preceding the MC by 40 msec in the bilateral frontocentral dominant area. Conclusions:(1) Regardless of enhanced cortical hyperexcitability in EEG in all, MC related potentials were recorded in only 3 out of 8 cases.(2) MC derived directory from the motor cortex in SPME. In MM, the subcortical origin which has the time-locked relation with the cerebral cortex was suggested.(3) Atonia of the mentalis muscle in non REM stage indicated dysfunction of the brainstem monoaminergic neuron in all.
