微电极记录与逆向激活一起使用，以监测脉冲传导沿着个别哺乳动物大脑轴突长达165天的时间。大约一半的轴突研究显示出稳定的传导速度和稳定的冲动活动的后效。其余的轴突表现出缓慢和渐进的增加或减少的传导速度随时间推移。在后面这些轴突中，冲动传导后效幅度的变化远不如轴突传导速度的变化明显。
Microelectrode recordings were used in conjunction with antidromic activation to monitor impulse conduction along individual mammalian cerebral axons for periods of up to 165 days. Approximately half of the axons studied showed a stable conduction velocity and stable aftereffects of impulse activity. The remaining axons showed slow and progressive increases or decreases in conduction velocity overtime. In these latter axons, changes in the magnitude of the aftereffects of impulse conduction were far less pronounced than were changes in axonal conduction velocity.
