Figure 11.

pre-FR is not correlated with the rate of sniff in the period before odorant addition. The period before odorant addition is defined as in Figure 4A. A, Example of the time course for nose pressure measured throughout a trial. Red line indicates application of odorant. B, Time course for the mean sniff frequency ± SD as a function of time (450 trials from 4 go-go sessions). C, D, Cumulative histogram for the correlation coefficient between per trial pre-FR and sniff frequency before odorant addition calculated for 36 odorant-unit pairs in 4 go-go sessions. C, Correlation coefficient (ρ) for pre-FR and sniff frequency. D, p value for the correlation coefficient (ρ). Blue represents not significant. Red represents significant (p value/pFDR: < 0.003/0.003, n = 36 SUs).
