Are these specialized cells especially designed to amplify and detect ambient electric and magnetic fields that are able to be sensed by the eye and the brain?
In a recent paper there was a description of the way endogenous fields were generated within a colony of cells. In this recent report a central cell was assumed to be fertilized and was able to polarize the other cells within a cell colony. This caused an electrostatic field to slowly begin to rotate by polarizing the proteins within the cell membranes of cells in the colony. Thus a range of fields over the electromagnetic spectrum evolved and appears to reflect the timing of the cell cycle.
In this present case, it may be that the folds within the plasma membrane of the rods and cones of the retina are designed to magnify and specify both the colour of the light entering the eye, and the motion of objects seen by the eye. There is a need for cell-cell communication between photoreceptor cells across the retina so as to specify the location of colour and movement across the retina.
In the human brain there are seen to be ‘folds’ within the brain. Birds also have a folded structure of the brain. Is this to create more cell-cell communications?
Yes, this kind of process is called "Self-Organization" and has a cosmic dimension. Do you know Erich Jantsch's book?

I think that T. Raptis is a specialist on this field:

Ask him!
Often the notion can be read that the cortex of the brain is
folded because this increases the area. But why would area
be an advantage? Access to the shores of liquor?
Volume provides space for cells.
An explanation could be that evolution has had no time
yet to develop a genetic program for arrangement
of cells in 3D. The cortex is a skin, and it was
easier for nature to modify a genetic switch to
increase the area than to create a 3D design.
Here are studies on sulci and gyri:

Interesting concepts! Folds provide more surface area and hence must be helping in some way.
Hi Jaya, All
Instead of 'surface area' try cell membrane and hence cell-cell communications. It seems this particular ability of human brains can 'connect the dots' more effectively than other creatures; Jerry nailed it; the surface activity equates to more neural pathways, more mutual 'wiring'.
I think it goes both ways too. If a person has too many 'interconnections' this might induce a 'brainstorm' or in other words, a TIA (temporary ischemic attack) or worse; this might be emotional perhaps, or intellectual , or even physiological in origin?
The potentials induced might be too big for the system to handle efficiently. Do we go into overload? I am aware that TIAs induce 'optical effects' within our optic nerves.
How do dreams become visual experience? Is there a two-way switch in the brain that alters the direction of flow of optical signals?
True, too many questions arising :)) since I am a microbiologist, I can relate this to a concept called Quorum Sensing, in micro organisms!
Wikipedia "Many species of bacteria use quorum sensing to coordinate gene expression according to the density of their local population."
This could be a field effect initially and then maybe the genes take over. See a recent paper by Daniel FelsArticle Endogenous physical regulation of population density in the ...
Dear Alfredo Pereira Junior
That's a great book about self-organization; I am slowly reading through it. You may be interested in 'Gravitational Structure of the Universe', one of the headings on the home page at the web site http://www.unifiedphysics.com/
The intricate folding will provide the more surface to the cells and these compact arrangement help them in their organisation and coordination during the physiological process.
The folding of the cell can be compared to the compact organisation of a vast nucleotide s in to a tiny chromosomes. (Nucleosome model ).
Quorum sensing is observed in the sporeformers especially in case of bacillus species .
