Fig. 6. fat-3 mutants have reduced evoked amplitude and reduced rates of spontaneous fusion but normal quantal size. (A) Representative evoked responses from wild-type and fat-3 animals. (B) The mean amplitude of the evoked responses is reduced in fat-3 (n=6) compared to wild-type (n=7) animals (P<0.03). (C) Representative traces of spontaneous fusion events in wild-type and fat-3 mutants. (D-E) The mean frequency of spontaneous fusion is reduced in fat-3 mutants (n=13) compared to wild-type (n=14; ^*P<0.02), while the mean amplitude of the individual events is normal. Data is plotted as mean ± s.e.m.
