1.当一个足神经节被移除时，蜗牛首先使用脚的未手术侧爬行，但在4-8周内，手术侧表现出从前到后的恢复梯度。2.神经节芽桥接缺失的神经节，轴突从完整的中央神经节投射到足部。3.在再生蜗牛的运动过程中，左右足神经对的节律性活动是相关的。4.其余足神经节中的振荡器驱动双侧协调活动。从大脑神经节通过芽到剩余的足神经节的再生投射足以启动运动。
1. When one pedal ganglion is removed, snails first crawl using the unoperated side of the foot, but in 4-8 weeks the operated side exhibits an anterior-to-posterior gradient of recovery. 2. A ganglion bud bridges the site of the missing ganglion and axons project from intact central ganglia into the foot. 3. Rhythmic activity in right and left pedal nerve pairs is correlated during locomotion in the regenerated snails. 4. The oscillator in the remaining pedal ganglion drives bilaterally coordinated activity. Regenerated projections from the cerebral ganglia through the bud to the remaining pedal ganglion suffice to initiate locomotion.
