Studies have been made on the electrical activity of the segmentary nerves and connectives of the abdominal nervous chain in the earthworm and leech. It was shown that the electrical activity of the isolated piece of the abdominal chain of the leech is manifested of periodic outbursts of impulsation. Presumably this central periodicity accounts for the discharge-like pattern of muscle rhythmic activity which was revealed in our earlier investigations. The electrical activity in the central nervous system of the earthworm depends on afferent influences which pass to the ganglia from the peripheral sensory nervous cells. Stimulation of the abdominal nervous chain did not result in extra discharges of muscle activity, but only affected some of the parameters of the latter.
人们已经对蚯蚓和水蛭腹部神经链的节段神经和结缔组织的电活动进行了研究。结果表明，水蛭腹部神经链分离片段的电活动表现为冲动的周期性爆发。据推测，这种中枢周期性是我们早期研究中发现的肌肉节律性活动的放电样模式的原因。蚯蚓中枢神经系统的电活动取决于从外周感觉神经细胞传递到神经节的传入影响。刺激腹部神经链并未导致肌肉活动的额外放电，而只是影响了后者的一些参数。
