Fig 4. The GABA_A receptor in LNs is involved in the behavioral habituation to cVA.

The defect of behavioral habituation to cVA was analyzed by interference of the expression of GABA_A receptors in a major class of olfactory neurons using pan-neuronal (A), ORNs (B), LNs (C), and PNs (D) drivers. The male flies were all trained with the male odor for 60 minutes, and then courtship responses to the females without (- M) or with (+ M) male odor in the lower cell of the chamber were measured (see Fig 1A). Bars indicate mean ±SEM. *, P < 0.05; ns, not significant from the Student's t-test with Holm's correction.
