Data represent pattern of serotonin-IR somata in the ventral nerve cords (VNC) of normal adult males and adult males that had received specified ablations; anterior is to the left. "0" indicates the presence of a soma; "-" indicates the absence of a soma in that position. CP1 (P3.aapp) is the posterior daughter of P3.aap. Ablations done during L3 (larval stage 3) were of CP precursors (Pn.aap), those done duirng L4 were of their posterior daughters (Pn.aapp). The number of individuals in which the pattern was observed is indicated at right. *In these individuals, the laser ablation either failed to kill the selected cell or the incorrect cell was ablated. CP 1 and 2 neurons [P(3-4).aapp] were typically more difficult to identify than the other CP neurons in L4 males.
