Fig. 4. Activation of at4A olfactory circuit by palmitoleic acid requires Or47b receptor.

(A) Sample traces of single-unit recordings of at4 sensillum in WT and Or47b mutant 7-day old males. Filled circles indicate large ORN spikes from at4A (Or47b); empty circles indicate smaller ORN spikes from at4C (Or88a). at4A spike activity was absent in the Or47b mutants. PA: palmitoleic acid; ML: methyl laurate. (B) Calcium activity at the axon terminals of Or47b ORNs in WT, Or47b3 mutant and genetic rescue males expressing GCaMP3 in the Or47b ORNs. (C) Calcium activity at the dendrites of Or47b projection neurons (PNs) in WT and Or47b3 mutant males. Gray-scale images show the Or47b/VA1lm glomerulus and pseudocolored images show representative odor-evoked responses. Mean ΔF/F is plotted against time, with line width indicating s.e.m. (n=5–9).
