Fig. 8.
Adaptive optics reveals fine neuronal structures. Axon terminals of the second-order olfactory projection neurons in the lateral horn regions are shown in a fly carrying the GH146-GAL4 and UAS-mCherry transgenes. Line profiles were plotted in the inset. Orange arrowheads: boutons of the projection neurons. Green arrowheads: branches of the projection neurons. Scale bar, 20 µm.
