  1. Values represent mean ± standard error (SE). Numbers in parenthesis indicate number of endplates (EPs).
  2. aQuantal content of EP potential (EPP) at 1 Hz stimulation corrected for resting membrane potential of −80 mV, nonlinear summation and non-Poisson release.
  3. bThe amplitude of the miniature EP potential (MEPPs) are corrected for resting membrane potential of −80 mV and a mean muscle fiber diameter of 5 μm. Temperature was 29 ± 0.5°C for EPP and MEPP recordings.
