http://www.ghuth.com A New Explanation for Light Interaction with the Retina of the Eye and the Vision Process Tue, 09 Mar 2010 22:36:25 +0000 http://backend.userland.com/rss092 en The surface of the retina of the eye is composed of approximately 120 million smaller rod and 6-7 million larger cone receptors. The organization of this tightly packed admixture of receptors is wildly asymmetric with  greater than 99% of the cones located in the central region that is termed the ... http://www.ghuth.com/2010/03/08/the-classical-wavequantized-particle-transition-that-takes-place-at-the-plane-of-retinal-outer-segments/ Based on this explanation of the vision process, I have speculated that there might be a geometrical symmetry lurking in the realm of seemingly structureless biology (search the term 'epitrochoid' on the homepage to see various entries on the subject).  It is probably time to recycle this idea. At least two ... http://www.ghuth.com/2010/02/24/is-there-a-geoemtrical-symmetry-at-the-heart-of-biology/ A piece from the New York Times of February 11, 2010 "From That Instant Thrill, Enduring Art, Now for Sale" recounts a melancholy end to a great man's dream. The piece refers to the history of Edwin Land and Polaroid instant photography. The seemingly total lack of interest in Land's color ... http://www.ghuth.com/2010/02/12/edwin-land-2/ I have noted in a number of previous Comments what I thought were important findings by  Engel et al  of , using their terms, ".... a wavelike energy transfer through quantum coherence in photosynthetic biological systems". The subject of their measurements were a type of antenna protein in green sulfur ... http://www.ghuth.com/2010/02/03/another-finding-of-quantum-coherence-in-a-photosynthetic-biological-system/ The following figure is Osterberg's classic measurement of retinal topography that  was published in 1935. It represents the distribution of cone and rod  receptors of the retina over the area extending from the central fovea to the periphery. This figure has been referenced countless times in vision textbooks since it ... http://www.ghuth.com/2010/02/02/a-new-explanation-of-the-vision-process-one-might-read-this-before-proceeding-to-the-body-of-the-work/ This new explanation of vision teaches that, as opposed to what has been historically believed, the process functions in two distinct and separate regimes in separate regions of the retina. These regions are: 1) the newly defined nanostructure of the plane formed by the array of receptor outer segments that ... http://www.ghuth.com/2009/12/02/two-separate-region-of-the-retina-function-to-effect-the-vision-process/ It is my premise that the literature of vision science has historically made a crucial mistake in  conjoining the concepts of electromagnetic wavelengths with (the hues of) color – that “long wavelengths actually represent the color red” etc. This shortcut has had major consequences. To begin, It is certainly well understood  ... http://www.ghuth.com/2009/11/13/the-terms-%e2%80%9cwavelength%e2%80%9d-and-%e2%80%9ccolor%e2%80%9d-have-been-improperly-used/ The following drawing is from Pirenne’s Vision and the Eye (Plate 6 of the Second Edition). The original reference for this drawing as noted by Pirenne is: Schultz (1866), Arch. mikr. Anat., 2, 175). Note the date of this reference!

My thoughts today after reading an article in the New York Times of October 25 “Plugging Into the Eye, With a New Design” by Anne Eisenberg. I have two thoughts  - one on the topic of ... http://www.ghuth.com/2009/10/28/more-thoughts-about-efforts-to-develop-of-a-retinal-prosthesis-to-aid-the-blind/ I have often written that "the eye is not a camera". But I have come upon a more definitive statement in Vision and the Eye by M. H. Pirenne (parapharased from page 120)...."the vertebrate retina..... covers the walls of a camera obscura on which an optical system projects an inverted ... http://www.ghuth.com/2009/10/26/where-it-all-went-wrong/
