Figure 5. Stimulation and analysis paradigm for estimating the RRP.
A. Representative stimulation paradigm (above) and electrophysiological responses (below) of the 60 Hz/30 stimuli protocol necessary to determine the RRP. B. Representative EPSC recording during a 60 Hz stimulus train at a typical NMJ. C. Average cumulative EPSC amplitude plotted as a function of time. A line fit to the 18-30th stimuli was back extrapolated to time 0; this y-intercept value is divided by the mEPSC value to determine the size of the RRP.
