Mechanisms of Odor Coding in Coniferous Bark Beetles: From Neuron to Behavior and Application
Figure 6
(a) Schematic drawing of the two types of sensilla in Ips typographus containing the A cell (large amplitude spikes) for cis-verbenol (cV), accompanied either by a nonresponsive (left column) B cell (small amplitude), or a B cell for 1,8-cineole (Ci) (right column). (b) Responses of both sensillum types to 1 ng cV (upper traces), and a binary mixture of 1 ng cV and 10 μg Ci (lower traces). Note the inhibition of the cV response during the response to Ci in the B cell. Black horizontal bars indicate the 0.5 s stimulation period. (c) Detailed response curves to cV and binary cV : Ci mixtures showing a Ci dose-dependent inhibition of the cV response only in sensilla that also contain the Ci cell (). Arrows indicate the onset of the 0.5 s stimulation period (modified from [8], with permission from the publisher).
