[Mediator and modulatory systems of the autonomic ganglia]

Autonomic ganglia are the complex functional systems within which the information coming through the preganglionic "input" is transformed and transferred to the postganglionic "output". The scientific papers of last years devoted to the investigation of the classical cholinergic and adrenergic and nowadays intensively investigated the so-called "noncholinergic-nonadrenergic" mediatory systems in autonomic ganglia are analysed in this review. The main classical and putative neurotransmitters, complex functional transmitter interactions and their role in the adaptive ganglionic transmission regulation in vivo are considered. The questions of modulatory processes in autonomic ganglia realizing with the help of regulatory peptides are under special consideration.
