Figure 4.

Odor responses of a subset of antennal ORNs are lost in acj6⁶. A, Odor response profiles of large basiconic sensilla of wild-type and acj6⁶ antennae. 6 ≤ n ≤ 12. Error bars indicate SEM. Odorants were applied as vapors of a 10⁻² dilution. B, Fate changes of antennal large basiconic neuron classes in acj6⁶. ab1A and ab1B are absent or electrically silent in acj6⁶ and are depicted by dashed lines. Uncolored neurons depicted by solid lines yield spontaneous action potentials but show no response to tested odors.
