When We Visualize Something, Does Our Brain Create One Image, or Two, as in One for Each Eye?
gpt
the brain embodies dozens of images of whatever you are viewing.

you have two eyes; in each eye a light image is absorbed by the retina, where it is transformed into a neural image that is transmitted to the thalamus, where the neural image is segregated into several layers, alternating between the different source eyes.

from the thalamus the neural image is sent to primary visual cortex ("V1") where stuff is still more-or-less segregated into left- and right-eye images, i.e. neurons in V1 tend to get most of their input from either one eye or the other. V1 then sends its neural image to other visual areas like V2 or MT, where new neural images are established, except that now they are merged - each neuron in post-V1 areas gets input from *both* eyes.

after V1 (and V2, and V3, and MT, and FEF, and etc), the number of distinct visual areas - and the neural images they embody - multiplies.   there are dozens of these images, which you might think of as representing distinct aspects of your visual experience (some areas embody more of the motion aspect; some more of the depthful aspect; some more of the color; etc). something like a third of the surface of the human cortex is occupied by these visual maps.

but then, it all *feels* like a single image, doesn't it? hmm...
