"To determine whether GABA plays a role in neuronal connectivity, we first compared in
unc-25(
e156) and wild-type animals the expression of a transgene, juIs1, in which GFP was fused to the C. elegans SNB-1 protein, a homolog of the synaptic vesicle protein synaptobrevin (Nonet et al., 1998), and driven by the
unc-25 promoter (Jorgensen et al., 1995)... We detected no abnormality in
unc-25(
e156) animals in either the shape or the density of the fluorescent clusters (Fig. 5A,B)"
