The Living State And Vision
September 12th, 2005 | No Comments »As opposed to the traditional view where a tacit assumption is that information about the vision process can be elicited from such types of measurements as microspectrophotometry of dead retinal sections, it is a fundamental tenet of this model that the retina be in the living state for visible light interaction to function! Only in the living state can the required sub-optical wavelength separations between adjacent receptor outer segments be maintained. The living state is therefore associated with spatial order in the sub-optical wavelength region. Land’s color vision measurements were made externally using living subjects… and living retinas… and from such measurements he correctly deduced the details of the vision process.
