In the cat isolated bladder, decentralization of the bladder plexus first decreased spontaneous unit activity. Later, after degeneration of preganglionic nervous fibres, intensified functioning of own reflex arches of the plexus maintained the coordination of activity in different areas of the bladder. Due to an increased excitability and chemosensitivity, the neurons are to a larger extent recruited in the activity of the reflex arches. Some bladder reflexes can be circuited within the bladder plexus.

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.
