After reading your footnote here is my intuition about the 2d pixels. Whatever things we experience are stored in our memory. The way to "draw" pixels on our brain is through experiencing( as in observing through our senses). So each of the experience is a pixel according to me. Trying to find lines and shapes in your vector graphics is basically finding patterns in the 2d pixels. Or what I would call learning in our case. What I think about learning that it is a top down approach. Each experience is very very specific. If you take any visual image from your memory, a huge amount of context is attached to it. The way we learn is we try to find patterns in these experiences and this commonality we save as a concept. Eg, we learn the concept of addition by seeing that when i get "2" "apples" from someone and if I had "3" "apples" already than I have "5" "apples". I have quoted these because in your childhood you will observer that whatever is in the quotes can very. You can have oranges instead of apples in the quote, or any other number other than 2 and 3. So by observing this you learn that if I get two numbers i can 'add' them. You need to already have an understanding of 'numbers' though. This understanding of 'numbers' or 'addition' is the pattern that you have found, we call it a concept. So, according to me, 2d pixels are your experiences. and concepts or notions are the shapes in the vector graphics. IMO Why you cannot convey your intuitions can be attributed to the fact that we have words associated with well known concepts. You learn words by associating them with the concepts you have learned. But many concepts do not have words associated with them. Also The concept might made up of complicated combination of small concepts that you find difficult to break down in simpler language. (I am also not a neuroscientist, but I have worked on the development of a neurology research s/w for few months.)
