Abstract

Noradrenaline caused a significant increase of the multiquantal endplate currents (EPC) amplitude, the EPC rising phase/the rising phase of miniature EPC ratio diminishing, at that. Noradrenaline seems to synchronise the process of quanta secretion in the EPC generation. Thus when a single stimulation of motor nerve results in release of several tenths of a transmitter, noradrenaline may increase the multiquantal EPC amplitude through synchronising of the transmitter release involved in the generation.
