1958W. A. H. Rushton in Nature 13 Sept. 691/1 Fig. 2 shows the results of partial photolysis of the normal fovea using red and green lights. This reveals two distinct pigments. One is the pigment of the protanope but in rather small amount; the other is a pigment which absorbs maximally at about 590 mµ and predominates. This latter pigment may be named ‘erythrolabe’ (= red taking), the protanope pigment ‘chlorolabe’, and the blue-sensitive pigment which does not here concern us, ‘cyanolabe’. 1959Optica Acta VI. 171 As the interaction between perceptual and physical processes is not likely to take place at a receptoral level, the terms chlorolabe and erythrolabe..are here replaced by C.P.540 and C.P.600. 1973Nature 18 May 168/2 Curve 2 is erythrolabe, present alone in the deuteranope. |
