Fig. 1. Reconstructed glomerular structure (A-D) of the anterior aspect of the antennal lobe (AL) of the female S. littoralis moth and a typical optical section (E) of the AL. (A) Right and (B) left ALs of the same female, respectively; (C,D) the left ALs of two other different individuals. Landmark glomeruli (red) are denoted by the letters A-F. The other glomeruli are roughly divided into three groups (dark green, yellow and pink) and numbered to facilitate the use of the figure as a reference for the identification of glomeruli targeted by responding neurones (see the text). AN, antennal nerve; LC, lateral cell body cluster; MC, median cell body cluster. Scale bars, 100 µm.
