[Proceedings: Interrelations between cholinergic and monoaminergic mechanisms in the determinism of spontaneous electrical activity in the central nervous system of scorpion (author's transl)].
Spontaneous electrical activity of the cerebral nervous system of Scorpion is characterized by potentials of 30 muV, and of average frequency varying between 200 et 400 impulses/min. This activity is enhanced by acetylcholine, and inhibited by adrenaline, nor-adrenaline, and serotonine, from a pharmacological study, it is assumed that spontaneous electrical activity of cerebral nervous system is due to cholinergic neurons, and antagonized by a serotoninergic system.
