[A statistical analysis of the change in spontaneous quantum secretion of a mediator in the presence of carbacholine in rat neuromuscular synapse].
Time of appearance and amplitudes of miniature end-plate potentials were studied statistically during the carbacholine action on the rat soleus muscle. Facilitating effect of carbacholine on the spontaneous quantal transmitter release did not change time distribution of miniature end-plate potentials. It is suggested that this effect of carbacholine was rather due to an increase in the activity of releasing sites, than due to an increase in their number.
