Supplementary Figure 10

a. Behavioral conditioned response (CR, the half-height-time of the inhale that triggers the CS, mean±SEM) during the first third of the acquisition trials, the 2nd, and the last third (F=5.16, p=0.002, ANOVA).

b. Neural response (firing rate evoked by the CS, mean±SEM) during the first third of the acquisition trials, the 2nd, and the last third (F=2.76, p=0.04, ANOVA).

c. Comparing rate of change for the neural response vs. the behavioral response on an individual basis (each dot is a neuron in one conditioning session). Upper: by fitting an exponential function to each and plotting λs; Lower: by fitting linear regression and plotting the slope.

Solid lines represent the identity (upper: p=0.3, χ2=1.0; lower: p=0.04, χ2=4.5).

d. Larger response for the CS that decays with distance from it, when counting spikes (left) or number of responding neurons (right). Insets show the same for the surrogate data.
