Abstract
The movement correlates of unit activity in medullary reticular formation cells were observed in unrestrained cats. Fifty-four percent of these cells had “laterally asymmetrical” movement relations and 38% had “laterally symmetrical” movement relations. All cells that discharged in relation to active lateral movement of the spinal column discharged preferentially in relation to ipsilateral movements, while all cells responding to passive lateral movement discharged preferentially in relation to contralateral movement. Cells related to movements of the vertebral column in the vertical plane and a small number of units related to facial, laryngeal, paw, and other movements were also found. The specific motor relations of reticular formation cells may explain the findings of previous lesion, stimulation, and recording studies.
摘要
在未受约束的猫身上观察了延髓网状结构细胞单位活动的运动相关性。这些细胞中有54%具有“侧向不对称”的运动关系，38%具有“侧向对称”的运动关系。所有与脊柱主动侧向运动相关放电的细胞均优先在同侧运动时放电，而所有对被动侧向运动作出反应的细胞均优先在对侧运动时放电。还发现了与脊柱在垂直平面内的运动相关的细胞以及少数与面部、喉部、爪子和其他运动相关的单位。网状结构细胞的特定运动关系可能解释了先前损伤、刺激和记录研究的结果。
