From: Different expression domains for two closely related amphibian TAARs generate a bimodal distribution similar to neuronal responses to amine odors

Figure 3

Quantitative analysis of spatial patterns.

Basal-to-apical distributions were quantified for olfactory receptor genes and odor responses. Top row, receptor gene (left panel) and odor response (right panel) distributions are shown as histogram of relative height (0, most basal; 1, most apical position; bin size 0.1, bin center is shown). Left panel, taar4a (brown) is centered apical; taar4b (green) shows a basal peak. Right panel, amine responses (blue) show a bimodal distribution. Second row, distributions are depicted as empirical cumulative distribution function (ECDF). Color code as above, for comparison to the amine responses the receptor distributions are shown in grey in the right panel. **p < 0.01. Third row, medial-to-lateral distribution is shown as bar graph for TAAR4a, TAAR4b, amine responses and amino acid responses (values taken from2 for comparison). Bottom row, basal-to-apical distributions are shown independently for each segment of the medial-to-lateral distribution depicted above. Medial segment, blue; intermediate segment, red; lateral segment yellow. Note that for both taar genes and amine responses the height distribution is undistinguishable between segments, in contrast to the significant difference between lateral and non-lateral amino acid responses (right panel). **p < 0.01.
