FIG. 1

(Color online) Spatial arrangements of chicken cone photoreceptors. The leftmost panel shows a flatmount preparation of a post-hatch day 15 chicken retina with colored oil droplets within the inner segments of the five cone photoreceptor types. Size bar = 10 µm. The additional panels (from left to right) depict the same field of view under illumination with ultraviolet, blue, and green light, respectively. Oil droplet autofluorescence permits subtype classification of the individual photoreceptor cells and determination of their spatial coordinates. These figures derive from Ref. [18].
