      Statement
      Reference

      Spontaneous miniature excitatory junction potential (mEJP) frequency at the neuromuscular junction is increased compared to controls in larvae expressing Syt1KA.Scer\UAS under the control of Scer\GAL4elav.PU in a Syt1AD4 background. mEJP amplitude is normal. The mean amplitude, rise time, decay time, peak half width and area of the evoked EJP response are all normal in the mutant larvae. The number of synaptic vesicles is normal.
