Figure 7.

Effect of temperature and the TrpA1 antagonist, HC-030031, on the excitatory response of the lateral styloconic sensillum to 0.1mM AA. The top row of panels shows the effect of (A) decreasing sensilla temperature alone, (B) the antagonist alone, and (C) decreasing sensilla temperature in the presence of the antagonist. The bottom row of panels shows the effect of (D) increasing sensilla temperature alone, (E) the antagonist alone, and (F) increasing sensilla temperature in the presence of the antagonist. Note we used 10 sensilla (each from different caterpillars) to generate all of the data in the top row of panels, and a different set of 10 sensilla to generate all of the data in the bottom row of panels. Below each bar within a panel, we indicate sensilla temperature, and whether the TrpA1 antagonist was (Ant) or was not (Con) present in the 0.1mM AA solution. Within each panel, we indicate when the black bar differed significantly from the white bars (P ≤ 0.05, Tukey multiple comparison test) with an asterisk. Each bar reflects mean ± standard error.
