What is this ?
The question asked by yourself is an emergence of consciousness (attention).
Your mind order now to your brain
to search all visual files stored in
the past in order to find if they have
similar visual property in common with
this image.
Consciousness will be
in fact no more than the
behavior of a vast assembly
of nerve cells and their
associated molecules
(hypothesis in materialism).
"We expect that, at any moment in time, consciousness will correspond to a particular type of activity in a transicent set of neurons that are a fraction of a much layer of potential candidates."
The questions at the neural level then become:
* Where are these neurons in the brain?
* Are they of any particular neuronal type?
* What is special(if anything) about their connections?
* What is special(if anything) about the way they are firing?
(Koch and F.Crick)
* Towards a science of consciousness

* The visual pathway from the retina
to the primary visual cortex.

(From The Astonishing Hypothesis by F.Crick)
* * The lens focuses the image of the visual field onto
a thin sheet of cell, the retina at the back of the eye.
In one of its layers are located the four kinds of photoreceptors
that respond to the photons of the incoming light.
one type: rod cell - - -The rods, of which there are over 100 million in each eye
responding mainly in dim light.
three type: cone cell - - - The cones, of which there are about 7 million,
are active in bright light. Each type respond to a
different range of wavelength of the incoming light.
Because of this we are able to see colors.
