Slow negative potential preceding voluntary self-paced middle finger extension, as recorded from scalp electrodes by backward averaging technique, was absent in two patients with dyssynergia cerebellaris myoclonica (Ramsay Hunt syndrome); but present in two patients with cerebellar cortical degeneration. As the main pathological lesion in Ramsay Hunt syndrome is in the dentate nucleus and its efferent pathway, the present results are in conformity with the experimental finding that the premotor and motor cortices receive strong inputs from the cerebellar efferent system.
通过反向平均技术从头皮电极记录到的、在自主自定速度的中指伸展之前出现的缓慢负电位，在两名肌阵挛性小脑协同失调（拉姆齐·亨特综合征）患者中未出现；但在两名小脑皮质变性患者中出现。由于拉姆齐·亨特综合征的主要病理病变位于齿状核及其传出通路，目前的结果与运动前皮质和运动皮质从小脑传出系统接受强烈输入的实验结果一致。
