用视频增强DIC光学显微镜观察了毛细血管蓝藻运动神经网的神经元。轴突内可见多种细胞器，许多细胞器是可移动的。为了量化运动，细胞器被分为三类(大、中、小)，并检查了不同颗粒类型所显示的运动速度、方向和类型。运输颗粒的整体行为和运动速度与其他物种的轴突中的行为和运动速度相似。最大的颗粒，主要是线粒体是运动最慢的，但也是唯一逆转运动方向或与其他颗粒相互作用的颗粒。小颗粒的运动速度最快，但它们和中等大小的颗粒都是连续输送的。此外，这些轴突中的线状成分发生了相当大的横向移动。
Neurons of the motor nerve net ofCyanea capillatawere examined using video‐enhanced DIC optics. A variety of organelles were visible within the axons and many were mobile. To quantify the movement organelles were divided into three classes (large, medium, and small) and the rates, direction, and types of movement displayed by the different particle types examined. The overall behavior and rates of movement of transported particles were camparable with those in axons from other species. The largest particles, mainly mitochondria were the slowest moving but were the only particles to reverse their direction of movement or to undergo interactions with other particles. The fastest movement was by the small particles, but both they and medium sized particles were transported continuously. In addition, the linear elements in these axons underwent considerable lateral movement.
