The spontaneous and the visual and vestibular induced activity of axotomized abducens motoneurons (ABD Mns) has been recorded in alert cats. Axotomy was carried out peripherally in the ocular orbit. ABD Mns were identified by their antidromic activation from the VIth nerve. Control Mns showed a clear relationship with eye position and velocity in the horizontal plane, whereas axotomized Mns showed a remarkable variability in their antidromic activation, a rapid fatigability during eye fixations and a decreased sensibility to eye velocity. Occasionally, axotomized Mns fired a short burst of activity before saccades in the off-direction. Functional involvements of described findings are discussed.
在清醒的猫身上记录了轴突切断的展神经运动神经元（ABD Mns）的自发活动以及视觉和前庭诱发的活动。轴突切断术在眼眶周围进行外周操作。通过来自第六神经的逆向激活来识别ABD Mns。对照运动神经元在水平面内与眼位和速度呈现明显的关系，而轴突切断的运动神经元在其逆向激活方面表现出显著的变异性，在眼球固定期间快速疲劳，并且对眼球速度的敏感性降低。偶尔，轴突切断的运动神经元在反方向扫视之前会短暂爆发活动。文中讨论了上述发现的功能意义。
