Observation of dendritic terminals of ddaC and coimaging with muscles. A, B, Images of two larvae of NP7028 GFP[S65T]/GFP[S65T] at 26–29 and 51–53 hr AEL, respectively. Close-up views of dendrodendritic contacts between adjacent ddaC neurons. In the neutral zone (bracket in B), terminals were closely apposed or turned away before crossing each other (arrow) and sometimes it was difficult to identify dendritic tips (arrowheads). C, D,Venus-pm/+; NP7028 GFP[S65T]/MHC-CD8-GFP-Sh in a third instar larva. A muscle attachment site in C (box) was magnified inD. Dendrites passed through splits of muscle bundles (D). Scale bars: A, 20 μm;B–D, 50 μm.
