Figure 5.

Presynaptic and postsynaptic polarity of the newly identified GFC neurons. GFC neuronal polarity is shown using the dendrite/soma label DenMark (magenta) and the presynaptic label synaptotagmin::GFP (Syt::GFP, green). Substacks of the regions of interest for each GFC are shown for DenMark (column 1) and Syt::GFP (column 2), with above and below paired comparisons (image column 3). Arrows indicate the position of the IB. GFC schematic representations are shown (center column), with regions of interest outlined in black boxes. A, GFC1 (78A06-Gal4) processes are labeled by presynaptic Syt::GFP in both TG1 (top) and TG2 (bottom) segments, while the IB is labeled by postsynaptic DenMark. B, GFC2 (73C07-Gal4) processes in TG2 (column 1) are colabeled by both DenMark (column 1) and the Syt::GFP marker (column 2). The IB is labeled by presynaptic Syt::GFP, but also has the DenMark signal (column 4). C, GFC3 (24H07-Gal4) has punctate Syt::GFP within the finger-like processes in TG3 (column 2). The IB is labeled by DenMark, with no Syt::GFP marker (column 4). GFC3 processes along the GFI axonal bend also express the DenMark label (arrowheads).
