Figure 2. AC neurons are thermosensors.

Figure 2

a, AC (arrowhead), LC (arrow) and VC (double arrow) neurons. b, dTRPA1 minigene expression. c, AC locations (antennae removed). d, AC projections. e, Left, AC processes labeled using dTrpA1SH-Gal4;UAS-myr:RFP. Also labeled are cells that express dTrpA1SH-Gal4, but do not detectably express dTRPA1 protein [also see a]. Right, camera-lucida-style outline of AC projections. f–g, AC projections to AL (f) and SOG (g). h–j, G-CaMP-labeled AC’s. Two AC’s sometimes imaged simultaneously (h). k–l, Warmth-responsive G-CaMP fluorescence of AC’s. m, Maximum F/F each AC imaged. AL, antennal lobe; SOG, subesophageal ganglion; SLPR, superior lateral protocerebrum; eso (asterisk), esophagus.
