Responses of wing taste sensilla to different chemicals. Spiking activity recorded from wing taste sensilla in males and females in response to KCl, NaCl, quinine, sucrose, E. coli, and LPS. (A) Responses of female flies. (B) Responses of male flies. Each point represents the average ± s.e.m. from n = 51 to 89 recordings obtained from a total of 10 insects. The concentration of each stimulus is reported on the abscissa as the log₁₀ of the molar concentration for KCl, NaCl, quinine, and sucrose, as log₁₀ of the density per ml for dead E. coli and as mg/ml for LPS.
