Rethinking the Process of Vision
A New Explanation for Light Interaction with the Retina of the Eye and the Vision Process
This BBC video above "Colorful Notions" from 1985 first summarizes the classical theory of color vision and follows with the ideas of Edwin Land who personally explains and demonstrates his experiments. It can be viewed as an introduction to this work.

BRIAN HAGAN

The paper:
“The Mathematical Transformation of Growth and Form – I Transferring the Wave-Particle Duality From Physics to Biology and Proposing Wave Interaction as a Key Determinant in Biological Structure” by B.E. Hagan and B. L. Reid, Medical Hypotheses, 6, 559-609, 1980
I met Brian Hagan some years ago while attending a birthday celebration for a good friend of mine, Felix Guttman of Macquarie University, in Sydney, Australia. I became aware very quickly that Brian was an extraordinary individual. In a subsequent conversation with him it became apparent that he was every bit at home in five dimensions as we normal mortals are in three (I even remember a curious habit he had of rolling his eyes towards the top of his head when discussing multi-dimensional space)! Brian was a surgeon of some renown in Sydney and I remember him remarking that he practiced medicine to support his real avocation – mathematics. I recently attempted to contact him on the web and learned that he had died in 2007.
I commend this paper, that I believe will turn out to be seminal, to anyone who thinks. It lucidly portrays the process of Fourier transformation. I humbly acknowledge that it started me on this what has been this lengthy study of the eye and vision.
In this context, a quote from the paper (p.581):
“The two views of matter, wave or particle, are thus not really divorced, but rather, are inseparably connected through the Fourier transforming process. They are merely different aspects, in the true sense of the word, of the same reality. We will later mention the proposition that the human eye can make these Fourier transformations and so, probably, can the brain.”
Hagan proceeds to reference Karl Pribram (Pribram et al, The Holographic Hypothesis of Memory Structure Brain Function and Perception”)
”Many difficulties are resolved by focusing on a single fact that everyone agrees to: when a diffracting object is placed in the front focal plane of the optical apparatus (pupil, and converging lens), a Fourier transform exactly describes the optical “image” at the back focal plane within the eye…. Thus the optical apparatus (especially the lens) operates a phase adjuster integrating interference patterns among waveforms (due to diffraction) into an optical image… taking this anchor of agreement as a starting point allows the concept of a retinal image to be separated into an “optical image” or “flow” and a “retinal process”. From the beginning, clear cut differences can be readily identified in the organization of optic array, optical flow, and retinal process”
The bold emphasis in the forgoing noting “phase adjustment” is precisely the capability that I attribute to the fundamental light interaction structures of the retina.
There is nothing new under the sun!
