Expression ofVoila1 in the adult nervous system of 4-d-old flies. A, Head cuticle with a complete proboscis. B, Frontal section (10 μm) of the brain.C, Anterior wing margin. D, Frontal view of a whole brain. Expression of the β-galactosidase inVoila1-UAS-lacZ males (A, C, D). Anti-tau labeling onVoila1 UAS-tau male (B). The main peripheral nervous structures (shown on A) are the third antennal segment (A), the labial palps (LB), the labral sense organ (LSO), the ventral cibarial sense organ (V), and the maxillary palps (MX). The arrow onC indicates neuronal expression associated with a wing gustatory sensillum. In the brain, structures strongly labeled with TAU (shown on B) are the mushroom bodies (MB;arrow on D) and the antennal lobes (AL). Scale bar, 25 μm.
