me and a friend of mine had a brain-related discussion that we hope you can help us out with.
I argued, since I can visually "compose" a scene from my imagination, and answer color- and geometry-related questions about it, the visual center must necessarily hold a "rendered" version of that scene, i.e. in some preprocessed format but still containing the actual information needed to theoretically read it out and render it on a computer screen without accessing the memory.
He argued, that there's no point in actually composing the image since the visual center can process associations from the brain just fine, so it's enough to just hand the visual center the associations and let it analyze them on-demand - i.e. imagination is a hub of associations rather than a buffer of pseudo-image data.
So I guess the crucial question here is:
on "seeing", a scene is decomposed into objects, which are stored separately. Does this step happen before, in, or after the stage that handles imagination?
Thanks for your replies.
