I'm not sure what your question is. I'm not saying that we don't see 
mental pictures, I'm saying that the pictures are not the things being 
transmitted and received in the brain. Much like in a TV, there are no 
pictures being send around the circuitry, there are electrons in wires.

The pictures are higher-level constructs.
