Synaptic activity regulates termination at the anterior, but not the posterior, tip of the dorsal cord. Quantitation of termination defects at (A) the anterior and (B) the posterior tip of the dorsal cord using P _unc-25 GFP (juIs76) for the indicated genotypes. For each genotype, the mean is shown from five or more counts (at least 20 worms/count). Analysis was performed on young adults grown at 23°C. Error bars represent the standard error of the mean. Significance was determined using an unpaired Student’s t test. ***P <0.001, **P < 0.005, ns, not significant. wt, wild-type.
