Quantitative assessment of distribution of v2r-related OlfC expressing neurons along the vertical z-axis (height within the organ). Height within the olfactory organ was quantified as section number in a series of horizontal sections, and normalized to the total number of sections containing sensory epithelium, using the same set of cells, for which laminar height was determined. Relative height within the organ ranges from 0 (top section, near to the opening of the bowl-shaped olfactory organ) to 1 (bottommost section). a The resulting distributions are shown binned (histogram, top row) and unbinned (ECDF, bottom row). The color code for the OlfC genes is the same as in Figs. 3 and 4 to facilitate comparisons between different positional parameters. Light grey curves in the ECDF plot for each of the tested OlfC genes represent the distribution for individual olfactory organs. Due to the smaller number of cells, scatter is increased. b Overlay of the distributions shown individually in panel a), both as histogram (left panel) and ECDF (right panel)
