Abstract

Bursting activity in cells cross-correlated with electromyographic (EMG) activity during parkinsonian tremor. Statistically significant evidence of cross-correlation was found for 49% of cells located at the lesion target for relief of tremor. Statistically significant correlation was found for 90% of cells having tremor frequency power greater than twice 'average power' at nontremor frequencies. This population of cells may be involved in the generation of parkinsonian tremor.

摘要

在帕金森震颤期间，细胞的爆发性活动与肌电图（EMG）活动相互关联。在位于震颤缓解病变靶点的细胞中，49%的细胞发现了具有统计学意义的相互关联证据。在震颤频率功率大于非震颤频率“平均功率”两倍的细胞中，90%发现了具有统计学意义的相关性。这群细胞可能参与了帕金森震颤的产生。
