Fig. 1. The antennal lobe (AL) of male and female Z-strain O. nubilalis.
(A) Confocal section through a male AL. Overview staining: in green
-synapsin labeled with Alexa Fluor 488, and in red phalloidin
conjugated to Alexa Fluor 546. (B,C) Three-dimensional reconstruction of the
male AL in A. In pink and blue are the two large intertwined macroglomerular
complex (MGC) glomeruli; in yellow, the smaller posterior MGC glomerulus.
Ordinary glomeruli are depicted in gray, with darker shading indicating more
posterior positions. Orientation: L, lateral; V, ventral; D, dorsal; P,
posterior. (D) A confocal section through a female AL. Overview staining as in
(A). (E,F) Three-dimensional reconstruction of the female AL in D. In green
and orange are the two large female glomeruli (LFG1 and 2, respectively).
Ordinary glomeruli are depicted in gray, with darker shading indicating more
posterior positions. (G–J) Three-dimensional reconstructions of the MGC
of four different males. Note the variability in structure. Scale bars, 50
µm.
