FIG. 7.

Neurons expressing Drosophila TRPA1 (dTRPA1) fire tonically in response to modest heat pulses. A: whole cell patch recording of a MNISN-Is cell responding to bath heating. dTRPA1 expression is limited to motor neurons (MNs) alone (C380-GAL4,UAS-mCD8-GFP/+; Cha-GAL80/UAS-dTRPA1). B: MN firing rate as a function of temperature in genetic controls and in animals expressing dTRPA1. Results from whole cell patch (pink) and NMJ experiments (green) are plotted on same graph. In NMJ experiments, expression of dTRPA1 was driven by OK371-GAL4.
