Figure 1S. Location of SJs in Drosophila nerve fibers. (A-I) Nine consecutive serial sections display the region where SJs are formed along the length of the nerve fibers (arrows). These junctions are formed between the outer (perineurial) and inner glial membranes which run continuously along the length of the nerves. Scale bar=2μm.

Figure 2S. Axonal ensheathment, location of SJs and their molecular components. A schematic of a cross-section through a peripheral nerve fiber shows axons (a, pink) surrounded either individually or collectively by inner glial membrane (m, yellow). These, in turn, are ensheathed by the outer perineurial glial cell (P, blue) surrounded by a layer of connective tissue, the neural lamella (l, grey). Ladder-like electron dense structures representing the SJs are present between the perineurial and inner glial membrane, which represent glial-glial SJs. Putative axo-glial SJs are represented at the axonal and inner glial membrane interface, such junctions have been observed previously (Jia et al., 1993). Insets represent higher magnifications of the regions where SJs are present. Nrx IV, Cont and Nrg are all expressed in the glial membranes. Nrg is uniquely expressed in both the axonal and the glial membranes.
