In the cat isolated bladder plexus, cholinergic transmission from parasympathetic "entry" was shown to be less obvious at low-frequency stimulation and much more effective (up to 300-1800%) at a high-frequency one (1-20/sec). During posttetanic potentiation (up to 5 min) it is possible to reach the 100% saturation of ganglion motor pool. The phenomena of facilitation were shown to be conducted through presynaptic mechanisms. The facilitation processes are more obvious in the bladder plexus than in sympathetic ganglia and allow to filtrate low and amplify high frequencies of activation which is particularly significant during urine storage and evacuation.
在猫的离体膀胱丛中，副交感神经“传入”的胆碱能传递在低频刺激时不太明显，而在高频刺激（1-20次/秒）时则有效得多（高达300-1800%）。在强直后增强（长达5分钟）期间，有可能使神经节运动池达到100%饱和。已表明易化现象是通过突触前机制进行的。易化过程在膀胱丛中比在交感神经节中更明显，并且能够过滤低频并放大高频激活，这在尿液储存和排空过程中尤为重要。
