进行地形和功能测试以确定是否可以从人头皮可靠地检测到Rolandic mu节律（rythme en arceau），并描述其与猫感觉运动节律（SMR）和人枕骨α相关的时空和功能特征。节奏Mu活动很少在参考记录或主要的10 - 20个系统位置中清晰可见，但在14个研究对象中的7个中通过功率谱分析和功能测试检测到。它是最好的记录在紧密间隔的双极衍生从中央区域后中央沟，其发生在休息和对侧的手运动的反应的地形分析所示。Mu活动衰减随意运动和体感刺激，但视觉刺激的影响最小。其频率范围在α范围内。带（平均10.1Hz），但与枕叶α分离。节奏和稳定的频率跨越天。人类mu活动和猫SMR之间的解剖学和功能相似性表明，它们在功能上类似于静息节律，主要由体感系统的输入中断。感觉特异性α的概念讨论了μ节律，其中μ节律被概念化为中枢体感α。与枕叶视觉α形成对比的节律。节奏
Topographic and functional testing was conducted to determine if the Rolandic mu rhythm (rythme en arceau) could be reliably detected from the human scalp, and to describe its spatiotemporal and functional characteristics in relation to the feline sensorimotor rhythm (SMR) and the human occipital .alpha. rhythm. Mu activity was rarely visualized clearly in referential recordings or from the major 10-20 system locations, but was detected by power spectral analysis and functional testing in 7 of 14 subjects studied. It was best recorded in closely spaced bipolar derivations from central areas posterior to the central sulcus, as shown in topographic analysis of its occurrence at rest and its reactivity to contralateral hand movement. Mu activity was attenuated by voluntary movement and somatosensory stimulation, but was minimally affected by visual stimulation. Its frequency ranged within the .alpha. band (mean of 10.1 Hz), but was separate from the occipital .alpha. rhythm and stable in frequency across days. The anatomical and functional similarities between human mu activity and the feline SMR suggested that they are functionally analogous resting rhythms which are disrupted primarily by input to the somatosensory system. The concept of sensory-specific .alpha. rhythms was discussed, in which the mu rhythm was conceptualized as a central somatosensory .alpha. rhythm in contrast to the occipital visual .alpha. rhythm.
