http://www.ghuth.com A New Explanation for Light Interaction with the Retina of the Eye and the Vision Process Mon, 06 Oct 2008 16:39:02 +0000 http://backend.userland.com/rss092 en DISCLAIMER: Lest I be accused of poor scholarship (that has happened!), I will generally not in my Comments include references that I have previously used in other sections of this work. GCH   A recent paper ( Nature, “Quantum Secrets of Photosynthesis Revealed”April 12, 2007) supports my contention that ... http://www.ghuth.com/2008/10/06/femtosecond-response-support-of-my-explanation/ I was asked if I know of Karl Pribram’s proposal that consciousness is dependent on holographic structure and is therefore, in some sense, related to the vision process. I have certainly been aware of these ideas for years but felt that they were incomplete in not providing any ... http://www.ghuth.com/2008/09/07/pribram-land-holography-huth/ The first and fundamental interaction of visible light resulting in the formation of an image in the vision process occurs at the plane of the outer segments of retinal receptors. This interaction occurs spatially in light detection centers (“pixels”) that are of dimensions smaller than light wavelength in ... http://www.ghuth.com/2008/09/05/thoughts-on-the-vision-process-to-be-continued/ I have been off on other things but this idea needs mentioning. I earnestly solicit the thinking of others in developing the following thoughts.   My view of light interaction with the retina seems in coincidence with a holographic explanation of the vision process.   Quoting from Cathey (Optical Information Processing and ... http://www.ghuth.com/2008/08/12/holographic-vision/ I propose that the outer segment of retinal receptors is the point where a quantum reality, whatever that turns out to mean, transitions from the physics of the quantum to the regime of slower, classical physics. In theory, the existence and ... http://www.ghuth.com/2008/06/26/light-interaction-with-receptor-outer-segments/ The obituaries of the New York Times of June 1 noted the death of Alvin Marks at 97 years of age. As I have previously written, it was Dr. Marks' proposal for "antennas for visible light" that provided the initial inspiration for this ... http://www.ghuth.com/2008/06/01/alvin-m-marks/ The finding of a direct relationship between geometry and light wavelength on the retinal surface may be the most fundamental insight of this work. It is seen that the exact center, i.e., ~550 nanometers, is geometrically defined at a retinal eccentricity of approximately seven degrees. This degree of retinal angle ... http://www.ghuth.com/2008/05/29/relationship-of-geometry-and-wavelength-on-the-retina/ Please read this paper (J. Opt. Soc. Am, Vol.57, No.11, November 1967). The retina described by Wald corresponds almost exactly to the retinal response of my explanation by making the simple substitution of the term“rod-rod appositions” for “blue-sensitive cones”. Even his opening paragraph: “In 1894 Konig and Kottgen reported experiments ... http://www.ghuth.com/2008/05/28/i-suggest-again-that-one-read-george-wald%e2%80%99s-paper-blue-blindedness-in-the-normal-fovea/   This work, put very simply, reinterprets the long accepted (i.e., appears in almost every vision textbook!) 1935 retinal morphology data of Osterberg in terms of modern physics and nanotechnology and arrives at an entirely new paradigm for the vision process. An example of vision science being stuck in the ... http://www.ghuth.com/2008/05/22/looking-forwardwhat-this-new-paradigm-means-to-vision-science/ As anyone following this work will have noted, I assert that light interacts on the retina in three distinct geometrically defined regions formed by  appositions of the intermixture of cone and rod receptors and not within the receptors themselves. It even becomes possible to view the retina abstractly as ... http://www.ghuth.com/2008/05/20/please-understand-and-let%e2%80%99s-move-forward/
