Change in the quantal content of EPPs during the short train of stimuli at a rhythmical activity of synapses of 50 Hz. A – in controls and upon administration of 100 •uM choline. B –in controls, in the presence of 20 nM MLA and upon administration of choline subsequent to MLA. The Y axis shows the quantal content of EPP; the X axis shows the number of EPPs in the train, *p < 0.05 compared to controls
