I Again Suggest…….
February 27th, 2006 | No Comments »I again suggest that the Roorda group extend measurements (Nature, Vol.397, pp 520-522, 11 February 1999) of the color sensitivity of retinal receptors, using the same imaging and bleaching modalities, to beyond the one degree retinal angle reported in their Letter. I would like to see analogous images taken at 7-8 and 20 degrees. I would predict that they would observe an increasing density of green centers (which they term “cones”) until at 7-8 degrees the field would be all green. As one measures further to the 20 degree angle blue centers would begin to predominate.
