Ejp amplitude evoked by the release of a single vesicle is unaffected by para63 orOverine+

GenotypeMean ejp amplitude (mV)
wild type0.78  ± 0.06
para63 0.72  ± 0.04
Overine+(1)0.71  ± 0.08
Overine+(2)0.79  ± 0.05
  • Average amplitudes of successful ejps evoked by nerve stimulation in the presence of low (0.1 mm) bath [Ca2+] in larvae of the indicated genotypes. Under these conditions, most successful ejps result from the release of a single vesicle of transmitter. Only successful ejps were included in this calculation.Overine+(1) indicates overexpression ofine driven by the MZ1580 gal4 line.Overine+(2) indicates overexpression ofine driven by the gli-gal4 line. Values are presented as mean ± SEM. Data were collected from at least seven larvae for each genotype. Larvae were prepared as described in Materials and Methods and in the legend to Figure 7.
