Fishing lines, time-delayed guideposts, and other tricks used by developing pharyngeal neurons in Caenorhabditis elegans.
The 20 neurons that innervate the Caenorhabditis elegans pharynx form a simple nervous system that develops and operates in near complete isolation from the rest of the worm body and, therefore, offers a manageable degree of complexity for developmental genetics studies. This review discusses the progress that has been made in determining the mechanisms by which 4 of the 20 pharyngeal neurons develop, and emphasizes surprising processes that add to the classic growth cone guidance model which is usually thought to explain how most axons establish their trajectories.
