Concentration-Invariant Odor Representation in the Olfactory System by Presynaptic Inhibition
Figure 4
The transient dynamics of PNs in different odor concentrations. The firing rates of ORNs are uniformly distributed in the range of (0,20) Hz in the low concentration case and in the range of (0,100) Hz in the high concentration case. PN fires spontaneously before the application of the odor.
