记录是由单一的神经元在手区的人运动皮层，而外周生理刺激。这些细胞只对主动和被动的手部运动做出反应。触觉和听觉（点击）刺激无效。大多数细胞只被对侧手的运动激活，但如果任何一只手进行给定的运动，则可以激活大量细胞（16个中的4个）。在对主动运动作出反应的细胞中，一些细胞在自愿行动开始之前表现出放电增加。这些细胞被被动执行的相同运动所兴奋，这一结果表明该运动激活的感受器的感觉反馈。
Recordings were made from single neurons in the hand area of the human motor cortex while peripheral physiologic stimuli were applied. Such cells responded only to active and passive hand movements. Tactile and auditory (click) stimuli were ineffective. The majority of cells were activated only by movements of the contralateral hand, but a significant number (4 of 16) could be excited if a given movement was made by either hand. Of the cells responding to active movement, some showed an increased discharge before onset of the voluntary action. Such cells were excited by the same movement executed passively, a result that indicates sensory feedback from receptors activated by that movement.
