Nondirectional M6-LNs in VT12760-GAL4. A: M6-LN8. B: M6-LN9. C: M6-LN10. D: M6-LN11. E: M6-LN12. F: M6-LN13. A1–F1: MARCM labeling of single nondirectional M6-LNs (magenta). Arrowhead indicates the cell body. Brains are immunostained with anti-DLG (gray). The skeletal models in A2–F2 illustrate coverage of the M6 retinotopic columns by each LN. Scale bars = 50 μm.
