Serotonin (5HT) enhances the responses of PNs to cis-11-vaccenyl acetate (cVA). (A) Single optical plane through the AL reveals the DA1 glomerulus (hatched white outline). DA1 PN responses to the pheromone, cVA, before (B) and after (C) 5HT application. (D) Time course of fluorescent change (ΔF/F) in response to repeated pulses of cVA before (control) and after exposure to 5HT. (E) 5HT enhanced the responses to cVA (n=11 flies. *P <0.05), and this enhancement was blocked by the 5HT antagonist, methysergide (MS) (n=8; n.s., not significant). Data in D and E are represented as mean±SEM. ∫ΔF/F dt, integral of ΔF/F during the total response period. Scale bar=10 μm.
