本研究利用抽吸电极同时记录成年雄性S.曼森描述。自发的身体收缩，类似于蠕动波，以近似有节奏的方式发生。表面电位与这些收缩有关。伸展增加自发收缩的速率。5-浓度为10-6 M的羟色胺可增加收缩率，并增加收缩的复杂性。10-5 M的卡巴胆碱降低收缩发生的速率，也降低了每次收缩爆发的复杂性，10-4 M的卡巴胆碱完全抑制活动。
A method utilizing suction electrodes for simultaneous recording of electrical activity and motility of adult male S. mansoni is described. Spontaneous body contractions, similar to peristaltic waves, occur in an approximately rhythmic manner. Surface electrical potentials are associated with these contractions. Stretch increases the rate of spontaneous contractions. 5-Hydroxytryptamine at a concentration of 10-6 M increases the contraction rate and also the complexity of the contractions. Carbachol at 10-5 M decreases the rate at which contractions occur and also decreases the complexity of each contraction burst and at 10-4 M completely suppresses activity.
