Comparison of suprathreshold response profiles in mitral cells with subthreshold response profiles in AON neurons reveals that AON neurons are more broadly responsive at the synaptic level than are mitral cells at the output level. A, The number of mixtures that elicit subthreshold responses in individual AON neurons (black bar) exceeds the number of mixtures that elicit suprathreshold responses in individual mitral cells (gray bar) (χ² test, p = 0). B, More AON neurons respond to multiple components of an effective mixture than do mitral cells (χ² test, p = 4.4e-12).
