title: [Periodical variations of the level of acetylcholine during stimulation of torpedo electric organ].
abstract: When tissue samples of the electric organ of the Torpedo fish, are taken every second during a period of stimulation at 5/s, it is noticed that their acetylcholine level oscillates in a quasi-sinusoidal shape. The amplitude of the oscillation is of about 350 nmoles/g and its period of 4 to 6 seconds. The speed of acetylcholine formation during such a process is extremely high.
