Fig. 8. cab-1 mutations confer pre-synaptic defects. (A) Aldicarb sensitivity of wild-type and mutant strains. Animals were exposed to 1.0 mM aldicarb, and paralyzed animals were counted periodically. Twenty-five animals/plate were tested (three trials/strain). The standard error is shown at each point. (B) Levamisole sensitivity of wild-type and mutant strains. Animals were exposed to 200 µM levamisole. Twenty-five animals/plate were tested (three trials/strain).
