Fig. 6. Physiological and anatomical characteristics of broadly responding PNs in Lobesia botrana. (A) Example for a PN with excitatory responses observed for all tested compounds at 1 µg. Note the different delays in response to different compounds. This neuron is not included in the data set in Table 1, because the AL was damaged and the target glomerulus could not be identified. (B) Extended focus image of a stack of confocal sections through the intracellularly stained dendritic arborisations of the generalist PN 14 in glomerulus 37 (black outline). (C) Partial three-dimensional reconstruction of the AL containing the stained PN 14 in the anterior view Y+, indicating the innervated glomerulus 37 (black outline). Brain sketch indicates the orientation of the brain and the relative position of the AL (marked red). AN antennal nerve, DB dorsal border of the AL, OL optic lobe, SOG suboesophageal ganglion, numbers indicate ordinary glomeruli, bold numbers indicate landmark glomeruli. Horizontal scale bar in A, 500 ms, vertical scale bar in A, 40 mV. Scale bar in B 30 µm. Scale bar in C 30 µm.
