During stereotactic operations brain potentials were recorded from the zona incerta of Parkinsonian patients. When the patient performed a rapid contralateral elbow flexion in response to a light signal, a slow positive or positive-negative EEG potential preceded the EMG activation by 30-130 ms (average 60 ms) and extended into the biceps activation phase. It was not evoked by the light flash alone or by rapid passive flexion. The potential may be interpreted as a correlate of movement-related activity of cerebellothalamic pathways mediating command signals for rapid arm movements. In support of this assumption, a marked delay of contralateral biceps activation followed coagulation of the recording site.
在立体定向手术过程中，从帕金森病患者的未定带回记录脑电位。当患者对光信号做出快速对侧肘部屈曲动作时，一个缓慢的正性或正负性脑电电位在肌电图激活前30 - 130毫秒（平均60毫秒）出现，并持续到肱二头肌激活阶段。它不是由单独的闪光或快速被动屈曲所诱发。该电位可被解释为介导快速手臂运动指令信号的小脑丘脑通路与运动相关活动的一个关联指标。为支持这一假设，在记录部位凝固后，对侧肱二头肌激活出现明显延迟。
