The filaments on your tongue trap tiny particles and bacteria; the major proportion of odor-producing bacteria are found on the tongue.
They readily discriminate odors that differ in molecular identity or concentration and can also discriminate different proportions of two odors in a mixture [14], [15].
The proportion of consistently identified odors decreased significantly across retention intervals [ F 3, 79) = 9.61, P < 0.001].
More importantly, and as suggested by the descriptive data (Table 2), there was a positive correlation between the proportion of consistently identified odors and hit rate, r 81) = 0.50, P < 0.001.
[a] Expressed as the proportion of respondents annoyed by odors at each validation region, as obtained from questionnaire responses.
Nevertheless, and as reported above, a rather small proportion of the low familiar odors were still named consistently.
In this retrieval test, we recorded the proportion of bees responding to the odor.
The exposure-response model was a sigmoid model (Equation 1), based on Nicell et al. [ 34], who showed that individual thresholds for odor annoyance in a population are log-normally distributed: (1) A = 1 1 + e a ⋅ log e C + b Where A is the proportion of the population annoyed by odor, C is the NH3 concentration (μg/m) and a and b are constants.
For most analyses, since odors induced no statistical difference in the global proportion of respiratory-pattern activities, responses to odors were pooled.
The percent of odor responsive neurons was calculated by determining the proportion of cells displaying an average fluorescence (ΔF/F) greater than 10% after odor addition (for AWA and ASH) or odor removal (all other neurons).
4) In the Methods, you state: "the percent of odor responsive neurons was calculated by determining the proportion of cells displaying an average fluorescence (ΔF/F) greater than 10percentt after odor addition (for AWA) or odor removal (all other neurons)".
