The contractile activity of veins and the rhythmicity of the frontal progress were photometrically recorded from cine-film, at numerous points across the whole plasmodium. Graphic analysis of the obtained curves demonstrates the existence of common contraction rhythm over the entire network, coincident to the expansion rhythm of the advancing front. It is suggested that the plasmodium of Physarum polycephalum represents an imperfectly synchronized monorhythmic contractile system.
从电影胶片上，在整个原生质团的多个点上，以光度法记录了静脉的收缩活动和前沿推进的节律性。对所获得曲线的图形分析表明，在整个网络中存在共同的收缩节律，这与前进前沿的扩张节律一致。有人提出，多头绒泡菌的原生质团代表了一个不完全同步的单节律收缩系统。
