ABSTRACT
Up until this point the discussion of the mechanism of perception has been presented exclusively in perceptual modeling terms. However, eventually the perceptual model has to relate back to neurophysiology. How can the volumetric spatial world of phenomenal experience, whose boundaries appear so regular and spherical, possibly map to the irregular wrinkled two-dimensional surface of the cerebral cortex? Unless we can at least form some kind of mental image of the spatial relation between the nouminal brain and the phenomenal world, the perceptual model remains detached from our knowledge of the world, like a disconnected image hanging in space. I propose to make the connection between the two worlds of reality by elaborating the perceptual model developed so far, to show how the unity of perceptual experience can be resolved with the segregation of cortical architecture observed neurophysiologically, how a regular spherical percept of the spatial world of experience can be encoded in the convoluted slab of the cortical tissue, and how this convoluted space relates to the double mental image presented in chapter 1. This is done from both perspectives: from the inner perceptual world looking out at the objective physical world, and from the outer physical world looking in to the perceptual world.
