The analysis of multidimensional neurophysiological data poses difficulties for the scientist in understanding the often complex inherent data relations. This is particularly the case when neuromuscular cell discharge parameters are to be related to body segment movement characteristics in freely behaving animals or humans. The understanding of such data is greatly simplified if the recorded data can be visualized in an adequate way, and relevant data relations are thus highlighted. This report describes a rationale for display and qualitative analyses of muscle discharge patterns in relation to three-dimensionally recorded limb or body movements. The method is illustrated by creating spatial activation plots and spatial activation maps of the electromyographic activity in the first interosseal muscle in the human hand, but this rationale for data presentation can be applied to most excitable tissues that are activated in relation to body or limb movements.
多维神经生理数据的分析给科学家理解常常复杂的内在数据关系带来了困难。当要将神经肌肉细胞放电参数与自由活动的动物或人类的身体节段运动特征联系起来时,情况尤其如此。如果记录的数据能够以适当的方式可视化,从而突出相关的数据关系,那么对这些数据的理解将大大简化。本报告描述了一种用于显示和定性分析与三维记录的肢体或身体运动相关的肌肉放电模式的基本原理。通过创建人手第一骨间肌肌电图活动的空间激活图和空间激活图谱来说明该方法,但这种数据呈现的基本原理可应用于大多数与身体或肢体运动相关而被激活的可兴奋组织。
