Fig. 9. Anatomy of a local interneuron, which responded only to -farnesene. (A) The reconstruction of the entire neuron in an approximately frontal view shows that arborisations are much more dense in one glomerulus (36) than in the remaining glomeruli (see also B). (B) Single approximately frontal confocal section showing dense arborisations in glomerulus 36. (C) Single approximately frontal confocal section through the central part of the AL showing sparse, branching with varicosities in many glomeruli. AN antennal nerve, numbers indicate ordinary glomeruli, bold numbers indicate landmark glomeruli. Scale bars 30 µm.
