The human is not reacting to light.
Indirectly he is.
No.
The receptor, a complex combination of reactive material, many transduction processes, in a particular type of cell grandly named rod or cone cell is processing then signaling via release of transmitter substance, the detection of EM energy of a particular suite of frequencies.
It is doing this at the same time other rods or cones in the retina are signaling frequencies to which come from the same or similar sources upon which the eye is focused to which they are sensitive as well.
So it is never a cell responding. It is a bound population of cells covered by the range of boundary contrast signals accompanying them which is included in the stimulus to which the retinal cells are responding.
Along with location, there is information in the population of activity signaling cells on intensity of incoming EM energy from parts of the population of rods and cones currently signaling.
And that molecule does not have any information about light to share.
Since the only information being produced by the cell is EM energy of visible light your claim is patently false.
The cell has no information about light.
There is no need for restatement by receptor cells of what is the source of information a system restricted to exclusively responding to EM visible light energy. There isn't any tell from the cell the receptor is a particular place in the retina since that is obvious throughout the ascending system by it's design to respond to cells from this or that part of the retina. The cell actually reports how much, when, where and in relation to that of other receptor partners in the gross signal transmissions.
The brain has no information about light.
You keep repeating yourself as if the repetition will make it true. It doesn't.
All the information from the visual sensing system is information about light. That is because it is a system designed to respond only to light.
The human mind knows about light though. After centuries of human cultural advancement.
Right, you're wrong again. A baby can distinguish light A from light B as soon as it can be presented those signals.
I have all necessary valid criticism to expose your argument as a fraud.
Fuck. I'm just going to Complete starting from where you left off.
1.
That is how the brain creates the shape
, intensity, shading, movement, and color of of the object(s) viewed.
2. Color is by relation of cells with various opsin configurations being sorted. Remember. Black and white scenes are available before color renditions are available.
3. Shape is determined by neural process sub serving edge detection using relations between positive and negative propagation of signals being passed up tracts.
4.Your knowledge of the function of shape determination and processing is so rudimentary I won't shame you further.
