NeuroFIG 17: The left deirid commissure.
A. Neurons situated posteriolaterally to the terminal bulb send their axons to the VNC via the deirid commissures. Processes travel between the hypodermis and muscle and enter the VNC between cell bodies of the RVG neurons. (Orange line) Basal laminae of the hypodermis and muscle; (VBWmu) ventral body wall muscle.
B. Epifluorescent image from an animal expressing the reporter gene dat1::GFP in ADE, ventral view. (Arrowheads) Portions of the ADE processes that are within the deirid commissures. Magnification, 600x. (Strain source: S. Clark.)
