Figure 4.

Representation of thermal information in a normalized antennal lobe. Localization of 40 cold-sensitive (blue) and 7 warm-sensitive glomeruli (red) detected in 11 different antennal lobes, visualized from a ventral (A) and anterior (B) perspective, respectively. The three target glomeruli of the sensilla coeloconica (Sc) are shown as black spheres (positional data of the example shown in Figure 1B). The boundaries of the normalized antennal lobe (mean volume of 11 antennal lobes) are indicated by the dotted lines. The two Sc-L glomeruli are located in a region where no thermosensitive glomeruli were found. Sc-L, lateral target glomeruli; Sc-M, medial target glomerulus.
