Laser ablation implicates male CEMs in pheromone detection. Wild-type C. elegans males and C. elegans males with their CEPs or CEMs ablated are scored by the time required to reach a test spot containing C. remanei sex pheromone. Each single-worm attraction assay is indicated by a circle, and the arrival times are rounded to the nearest minute. Males that could not reach the spot within 30 min are scored as “>30”; males that were about to crawl off the slide were repicked to the start position and scored as “repicked.”
