Fig 6. Recurrent inhibitory circuit plastically reduces signal intensity.

(A) The Mz97 LNs provide presynaptic excitatory inputs into the Or67d ORNs in a naïve fly. (B) Continuous odor exposure facilitates the iLNs that provide inhibitory inputs to the Mz97 LNs. (C) Suppression of the Mz97 activity weakens the odor signal from the ORNs and downstream behavioral responses.
