Schematic representation of spatial coordinates measured. (A) Horizontal cross section of an olfactory epithelium. (B) Enlargement shows the radial parameter (r_i), measured from middle raphe between lamellae to center of labeled cell and normalized to maximal radius (r_o, including non-sensory area). One lamella is shown. (C) Enlargement shows the laminar height parameter (h_i), measured from the border between basal lamina and the sensory layer to center of labeled cell and normalized to maximal height (h_o, measured at position of labeled cell, as laminar height varies throughout the lamella). (D) The complete olfactory organ, all three spatial coordinates are shown. height-within-the-organ is measured as section number z, beginning with the most basal section still containing sensory surface (bottom to top).
