Analgesics can inhibit AITC sensitized thermal aversion.

A, The percent time larvae incubated with analgesic plus AITC (0.5μM) spent in the 28.5°C zone during a 28.5°C vs 31.5°C assay normalized to percent time larvae incubated in AITC (0.5μM) + vehicle alone spent in the 28.5°C zone. No AITC larvae were treated with 1% DMSO vehicle alone. B, The percent time larvae incubated with non-analgesic plus AITC (0.5μM) spent in the 28.5°C zone during a 28.5°C vs 31.5°C assay normalized to percent time larvae incubated in AITC (0.5μM) + vehicle alone spent in the 28.5°C zone. No AITC larvae were treated with 1% DMSO vehicle alone. * represent statistical difference from AITC (0.5μM) alone condition (2-way anova post hoc comparison) * p<0.05, ** p<0.01, *** p<0.001. Error bars represent SEM.
