(A) Number of cells analysed and characteristic parameters for distributions shown in (Fig. 3). (B) Pairwise comparisons of different genes and/or odor responses were performed using the Kolmogorov–Smirnov test of the unbinned height distributions or chi square test (for comparing cell number ratios between lateral, intermediate and medial segments). Values for amino acid-responsive cells were taken from2. Distributions were considered significantly different for p < 0.01.
